1 00:00:00,280 --> 00:00:02,840 Speaker 1: Brought to you by the reinvented two thousand twelve camera. 2 00:00:03,160 --> 00:00:08,920 Speaker 1: It's ready. Are you get in touch with technology with 3 00:00:09,039 --> 00:00:17,920 Speaker 1: tech Stuff from how stuff works dot com. Hello again, everyone, 4 00:00:17,960 --> 00:00:21,279 Speaker 1: welcome to tech stuff. My name is Chris Polette and 5 00:00:21,360 --> 00:00:24,040 Speaker 1: I am an editor here at how stuff works dot com. 6 00:00:24,079 --> 00:00:26,560 Speaker 1: Sitting across from me, one of my favorite peeps in 7 00:00:26,560 --> 00:00:29,720 Speaker 1: the whole world is senior writer Jonathan Strickland. Is it 8 00:00:30,080 --> 00:00:34,360 Speaker 1: a fast ship. It's the ship that made the Kessel 9 00:00:34,479 --> 00:00:38,680 Speaker 1: run in less than twelve post sex. She's fast enough 10 00:00:38,840 --> 00:00:43,559 Speaker 1: for you, old man. You have to get credit for 11 00:00:43,600 --> 00:00:46,720 Speaker 1: this quote. You actually have to. You can't just name 12 00:00:46,760 --> 00:00:49,240 Speaker 1: the original source. You have to figure out the secondary 13 00:00:49,240 --> 00:00:53,159 Speaker 1: source right well, and to be fair, the secondary source 14 00:00:53,680 --> 00:00:58,120 Speaker 1: paraphrases the primary source. So um, yes, we're going to 15 00:00:58,200 --> 00:01:01,560 Speaker 1: talk today about Star Wars Wars. This comes to us 16 00:01:01,560 --> 00:01:10,479 Speaker 1: courtesy of a little listener mail. This listener mail comes 17 00:01:10,520 --> 00:01:13,480 Speaker 1: from Eric, and Eric says, weeks ago, when Ronald Reagan's 18 00:01:13,480 --> 00:01:16,399 Speaker 1: on birthday came and went, it got me thinking about 19 00:01:16,480 --> 00:01:19,600 Speaker 1: his Star Wars satellite program. I know Star Wars involved 20 00:01:19,600 --> 00:01:22,319 Speaker 1: satellites and it theoretically would be able to kill any 21 00:01:22,400 --> 00:01:25,520 Speaker 1: bad guy. America set its sights on. However, I don't 22 00:01:25,520 --> 00:01:27,200 Speaker 1: know much about how it works. Could you do a 23 00:01:27,240 --> 00:01:30,600 Speaker 1: podcast on it? Thanks? Ps. Could Star Wars be able 24 00:01:30,640 --> 00:01:34,360 Speaker 1: to destroy Room Hilda and the Philosophizer? First of all, Eric, 25 00:01:34,880 --> 00:01:38,119 Speaker 1: it's not an assassination system, it's an anti missile system. 26 00:01:38,160 --> 00:01:41,120 Speaker 1: And second of all, nothing can stop Room Hilda and 27 00:01:41,160 --> 00:01:48,320 Speaker 1: the Philosophizer, So maybe some broad first, So you want 28 00:01:48,360 --> 00:01:50,680 Speaker 1: to talk a little bit about well, I guess before 29 00:01:50,720 --> 00:01:52,920 Speaker 1: we even talk about the Star Wars program, what we 30 00:01:52,960 --> 00:01:56,160 Speaker 1: need to do is take a little trip in the 31 00:01:56,200 --> 00:01:59,040 Speaker 1: way back machine. We haven't done that for a while. Now, 32 00:01:59,760 --> 00:02:03,480 Speaker 1: did uh? Did uh stuff you missed in history class? 33 00:02:03,520 --> 00:02:06,760 Speaker 1: Bring it back? Uh? You know? We actually we have 34 00:02:06,840 --> 00:02:10,360 Speaker 1: a secondary unit. Um. I when we when we did 35 00:02:10,400 --> 00:02:14,519 Speaker 1: the renovation on the the the studio space, I made 36 00:02:14,520 --> 00:02:17,680 Speaker 1: sure that we got a second one just for tech stuff. Okay, 37 00:02:17,680 --> 00:02:20,079 Speaker 1: good because they don't leave it plugged in. Right. Well, 38 00:02:20,080 --> 00:02:22,160 Speaker 1: this one over here, you'll you'll notice it looks kind 39 00:02:22,200 --> 00:02:25,280 Speaker 1: of like okay, so it looks like a third hand 40 00:02:25,520 --> 00:02:28,880 Speaker 1: um police call box. But trust me, it'll it'll work 41 00:02:28,960 --> 00:02:32,920 Speaker 1: just fine. So so let's all right, get in, all right, 42 00:02:32,919 --> 00:02:35,000 Speaker 1: I'm right behind here. Alright, you just budge over just 43 00:02:35,040 --> 00:02:37,240 Speaker 1: a little bit. Unfortunately, this one is not larger on 44 00:02:37,280 --> 00:02:39,480 Speaker 1: the inside than it is on the outside. Let's just 45 00:02:39,520 --> 00:02:43,839 Speaker 1: set this for October four, nineteen fifty seven, and uh, 46 00:02:44,040 --> 00:02:47,320 Speaker 1: push the button, Frank, I can't reach the button. All right, 47 00:02:47,360 --> 00:02:52,359 Speaker 1: I'll push the button, alright, And here we are October four, 48 00:02:52,520 --> 00:02:56,520 Speaker 1: nineteen fifty seven in this what was then the Soviet Union. 49 00:02:56,760 --> 00:03:01,480 Speaker 1: Get out is not roomy in here. Oh sorry, all right, 50 00:03:03,440 --> 00:03:06,799 Speaker 1: that's better. Hey, there's that that tune that's in tetris um. 51 00:03:06,919 --> 00:03:11,240 Speaker 1: So anyway, it's nineteen fifty seven, October four, Soviet Union. 52 00:03:11,280 --> 00:03:15,240 Speaker 1: You know what's about to happen? Does it beep? It does? 53 00:03:15,320 --> 00:03:17,480 Speaker 1: In fact, that's pretty much all it does. There's going 54 00:03:17,520 --> 00:03:21,079 Speaker 1: to be the launch of the Sputnik satellite, the first 55 00:03:21,160 --> 00:03:25,880 Speaker 1: man made satellite launched into Earth orbit deep In fact, 56 00:03:25,960 --> 00:03:28,400 Speaker 1: that is a direct quote. Yes, it's pretty much. All 57 00:03:28,400 --> 00:03:30,760 Speaker 1: it did was orbit the Earth and beep. But here's 58 00:03:30,840 --> 00:03:33,720 Speaker 1: here's the other important thing about sput Nick. It was 59 00:03:33,800 --> 00:03:36,080 Speaker 1: not only was it the first man made satellite, but 60 00:03:36,160 --> 00:03:39,920 Speaker 1: it made America, like the general public of America realized 61 00:03:40,520 --> 00:03:44,000 Speaker 1: that the Russians had developed technology that would not just 62 00:03:44,080 --> 00:03:47,880 Speaker 1: allow them to launch a rocket into space, but theoretically 63 00:03:48,280 --> 00:03:50,920 Speaker 1: launch a rocket from the Soviet Union that could go 64 00:03:51,000 --> 00:03:53,720 Speaker 1: all the way and reach the United States of America 65 00:03:54,520 --> 00:03:58,480 Speaker 1: right now, keeping in mind that this is shortly after 66 00:03:58,960 --> 00:04:01,320 Speaker 1: the end of a Wars, or at least much closer 67 00:04:01,400 --> 00:04:06,120 Speaker 1: than it is now, and people were still very concerned 68 00:04:06,120 --> 00:04:11,200 Speaker 1: about what was dawning as the atomic Age. With the 69 00:04:11,600 --> 00:04:15,240 Speaker 1: dropping of the the atomic bombs on Hiroshima and Nagasaki 70 00:04:15,280 --> 00:04:18,719 Speaker 1: that ended the Second World War, other countries were beginning 71 00:04:18,720 --> 00:04:21,320 Speaker 1: to test those realized that they were terrible weapons, all 72 00:04:21,320 --> 00:04:23,960 Speaker 1: of us in the world, everywhere, and you know, all 73 00:04:24,000 --> 00:04:27,800 Speaker 1: of a sudden it became a concern that other people, 74 00:04:27,920 --> 00:04:33,159 Speaker 1: especially you know, countries that were not necessarily friendly to 75 00:04:33,160 --> 00:04:36,200 Speaker 1: the United States and the Soviet Union had undergone what 76 00:04:36,360 --> 00:04:41,000 Speaker 1: can only be described as political turmoil over the decades 77 00:04:41,040 --> 00:04:44,080 Speaker 1: since World War One. Really, and sorry, I was dancing 78 00:04:44,080 --> 00:04:46,640 Speaker 1: around that. Yeah, but it's well, we have to talk 79 00:04:46,680 --> 00:04:49,160 Speaker 1: about it because the Cold War, that's what Star Wars 80 00:04:49,160 --> 00:04:52,200 Speaker 1: program is all about. Yes, it was so so we 81 00:04:52,279 --> 00:04:56,600 Speaker 1: had these political the strain on on the political relationship 82 00:04:56,640 --> 00:04:59,000 Speaker 1: between the United States of America and the Soviet Union. 83 00:04:59,000 --> 00:05:03,960 Speaker 1: They had dia trically opposing political philosophies, right, and now 84 00:05:04,040 --> 00:05:07,680 Speaker 1: these very very potent weapons which going from needing to 85 00:05:07,720 --> 00:05:11,280 Speaker 1: be dropped as bombs from planes to being equipped on 86 00:05:11,360 --> 00:05:15,479 Speaker 1: top of missile warheads. We're talking about longer and longer ranges. 87 00:05:15,760 --> 00:05:18,320 Speaker 1: What parts of the world can you hit with a 88 00:05:18,400 --> 00:05:22,039 Speaker 1: rocket of this type? And then suddenly there is a 89 00:05:22,120 --> 00:05:25,680 Speaker 1: thing in space that is beeping? But what does that mean? 90 00:05:25,720 --> 00:05:27,560 Speaker 1: Does that mean that you can hit anywhere in the 91 00:05:27,640 --> 00:05:30,600 Speaker 1: world if you launch the rocket from the right, you know, 92 00:05:30,640 --> 00:05:35,080 Speaker 1: at the right altitude and attitude and apogee right, yeah, yeah, exactly, 93 00:05:35,120 --> 00:05:38,279 Speaker 1: instead of having to send a bunch of aircraft to 94 00:05:38,360 --> 00:05:42,159 Speaker 1: fly over a target space and drop bombs, you know, 95 00:05:42,320 --> 00:05:46,320 Speaker 1: those aircraft could be intercepted and could be shot down. Um, 96 00:05:46,800 --> 00:05:50,200 Speaker 1: you could, uh, there were things that you could do 97 00:05:50,279 --> 00:05:53,360 Speaker 1: in that case. The thought of a missile being launched 98 00:05:53,400 --> 00:05:56,080 Speaker 1: across the world and then hitting your nation was much 99 00:05:56,120 --> 00:05:59,320 Speaker 1: more frightening because what could you do against that. Well, 100 00:05:59,360 --> 00:06:02,520 Speaker 1: that's what sort of propelled the whole idea of the 101 00:06:02,520 --> 00:06:05,880 Speaker 1: Strategy Strategic Defense Initiative or star Wars program. Well, let's 102 00:06:05,920 --> 00:06:07,760 Speaker 1: let's get back into the machine and get back to 103 00:06:07,800 --> 00:06:11,520 Speaker 1: modern day. Seriously, we have to cutphobic all right, well, 104 00:06:11,600 --> 00:06:14,440 Speaker 1: let's look just held deeply and get in all right, 105 00:06:17,000 --> 00:06:23,120 Speaker 1: shut up, we got to move this lever because okay, 106 00:06:20,080 --> 00:06:27,320 Speaker 1: great and we're back all right, let me just get 107 00:06:27,360 --> 00:06:31,280 Speaker 1: out of here. Okay, now somebody else can have that one. 108 00:06:31,320 --> 00:06:33,880 Speaker 1: The studio seems nice and room he now, doesn't it. 109 00:06:34,520 --> 00:06:36,760 Speaker 1: All right, So now that we're back in the present day, 110 00:06:36,760 --> 00:06:38,839 Speaker 1: we can talk a little bit about what happened after 111 00:06:38,880 --> 00:06:41,240 Speaker 1: the spot Nick launch. You essentially had a lot of 112 00:06:41,279 --> 00:06:45,640 Speaker 1: research and development poured into these these long range missile programs. Eventually, 113 00:06:45,760 --> 00:06:48,920 Speaker 1: the the intercontinental Ballistic missile or i C b M 114 00:06:49,040 --> 00:06:54,680 Speaker 1: became a product of this. So this began what was 115 00:06:55,240 --> 00:07:01,200 Speaker 1: a philosophy that was called later mutual assured destruction. Is 116 00:07:01,240 --> 00:07:07,120 Speaker 1: it a Is it any coincidence that the initials spell mad? Well, 117 00:07:07,400 --> 00:07:09,760 Speaker 1: you had to be mad to follow it, right, So 118 00:07:10,080 --> 00:07:13,440 Speaker 1: the idea of being that you, whoever has the most weapons, 119 00:07:13,840 --> 00:07:16,080 Speaker 1: gets to scare off everyone else from attacking you because 120 00:07:16,080 --> 00:07:18,160 Speaker 1: we have more than you. Yeah, the idea being that 121 00:07:18,160 --> 00:07:21,720 Speaker 1: that really the idea came down to each each side 122 00:07:21,840 --> 00:07:26,720 Speaker 1: of this opposing philosophy, this this cold war so called 123 00:07:26,760 --> 00:07:31,480 Speaker 1: because there weren't outright hostilities breaking out, uh that you 124 00:07:31,560 --> 00:07:34,400 Speaker 1: had to have enough weapons to ensure that you could 125 00:07:34,400 --> 00:07:36,920 Speaker 1: destroy your enemy, and both sides had it, and the 126 00:07:36,960 --> 00:07:40,520 Speaker 1: idea being that with both sides having these weapons, there'd 127 00:07:40,520 --> 00:07:43,000 Speaker 1: be it would be crazy to actually launch an attack, 128 00:07:43,040 --> 00:07:47,040 Speaker 1: because you would know that you would also be attacked 129 00:07:47,120 --> 00:07:49,960 Speaker 1: and that you would suffer just as your enemy suffered. 130 00:07:50,720 --> 00:07:53,280 Speaker 1: So that was the mutual assured destruction, the idea that 131 00:07:53,480 --> 00:07:56,040 Speaker 1: it's so dangerous to launch an attack, no one would 132 00:07:56,160 --> 00:07:59,920 Speaker 1: dare do so. Problem is that that relies on human 133 00:08:00,160 --> 00:08:03,320 Speaker 1: acting in a rational way, and that of course it's 134 00:08:03,320 --> 00:08:05,440 Speaker 1: not always the case. In fact, this you could argue 135 00:08:06,040 --> 00:08:09,360 Speaker 1: that this was the same philosophy that existed in Europe 136 00:08:09,440 --> 00:08:13,880 Speaker 1: prior to World War One, that European nations were building 137 00:08:13,960 --> 00:08:17,280 Speaker 1: up armed armies and navies. They were really pouring money 138 00:08:17,280 --> 00:08:20,720 Speaker 1: into their armed forces, with the idea being that if 139 00:08:20,800 --> 00:08:23,000 Speaker 1: you had a very strong armed force, no one would 140 00:08:23,000 --> 00:08:27,320 Speaker 1: ever dare attack you. So therefore, just by increasing tensions, 141 00:08:27,440 --> 00:08:31,160 Speaker 1: by by increasing the size of your military, you could 142 00:08:31,200 --> 00:08:34,439 Speaker 1: ensure peace, even though it would be a very tense piece. Unfortunately, 143 00:08:34,440 --> 00:08:37,920 Speaker 1: as World War One proved, that did not work. So 144 00:08:37,960 --> 00:08:42,720 Speaker 1: we tried it again with nuclear weapons um and and 145 00:08:42,760 --> 00:08:45,920 Speaker 1: to some I think just for the sake of clarification, 146 00:08:46,000 --> 00:08:47,640 Speaker 1: right now, I would say it's safe to say that 147 00:08:47,640 --> 00:08:53,040 Speaker 1: that that hasn't gone away. There's still huge nuclear stockpiles 148 00:08:53,840 --> 00:08:57,880 Speaker 1: in the United States and in USA, the former Soviet Union, 149 00:08:58,120 --> 00:09:01,040 Speaker 1: and and many other countries around the world now. And 150 00:09:01,080 --> 00:09:06,000 Speaker 1: even though the Soviet Union itself collapsed, it looks you 151 00:09:06,000 --> 00:09:08,800 Speaker 1: could you could say that the political and the political 152 00:09:08,880 --> 00:09:11,760 Speaker 1: attitude in what in the former Soviet Union is once 153 00:09:11,800 --> 00:09:16,720 Speaker 1: again at least at least somewhat antagonistic towards the United 154 00:09:16,760 --> 00:09:21,080 Speaker 1: States government. Right there, there are political tensions between the 155 00:09:21,160 --> 00:09:24,240 Speaker 1: United States and the countries that were in the former 156 00:09:24,280 --> 00:09:28,520 Speaker 1: Soviet Union. Well, you know, you can see, uh, even 157 00:09:28,520 --> 00:09:32,240 Speaker 1: some of our younger listeners will probably remember the tension, 158 00:09:33,000 --> 00:09:34,960 Speaker 1: uh if you follow the news at all, and I 159 00:09:35,040 --> 00:09:38,640 Speaker 1: recommend that you do. Um, the tension generated from North 160 00:09:38,720 --> 00:09:42,520 Speaker 1: Korea's fairly recent tests in the last two or three 161 00:09:42,600 --> 00:09:45,880 Speaker 1: years where they were testing nuclear weapons and and missile 162 00:09:45,920 --> 00:09:50,160 Speaker 1: technology bo um. And you know, of course this causes 163 00:09:50,160 --> 00:09:54,720 Speaker 1: a lot of tension with South Korea and Japan UM, 164 00:09:54,760 --> 00:09:57,040 Speaker 1: but also for for other countries around the world, even 165 00:09:57,120 --> 00:10:00,520 Speaker 1: even Europe, which you know probably you wouldn't wow. You know, 166 00:10:00,559 --> 00:10:04,560 Speaker 1: they're pretty far away, you know, still it affects these 167 00:10:04,559 --> 00:10:09,839 Speaker 1: things are no longer local conflicts with this technology. So, um, 168 00:10:09,880 --> 00:10:13,680 Speaker 1: you know, the ideas are it hasn't gone away, certainly, right. 169 00:10:13,720 --> 00:10:16,720 Speaker 1: You still have these political ideologies that are in opposition 170 00:10:16,920 --> 00:10:18,679 Speaker 1: with each other. But then you also have like global 171 00:10:18,720 --> 00:10:22,440 Speaker 1: corporations that span multiple countries, some of which have these 172 00:10:23,120 --> 00:10:28,120 Speaker 1: political ideologies that conflict with the corporation's home country. It's 173 00:10:28,160 --> 00:10:32,120 Speaker 1: main matters much more complicated. It's not just political, it's financial. 174 00:10:32,240 --> 00:10:36,320 Speaker 1: And you know, of course we're all nuclear weapons are nondiscriminatory, right, 175 00:10:36,360 --> 00:10:40,360 Speaker 1: they don't. They don't target just military installations, military personnel. 176 00:10:40,920 --> 00:10:44,480 Speaker 1: This is these are weapons that target enormous areas and 177 00:10:44,559 --> 00:10:48,520 Speaker 1: essentially are going to wipe out massive civilian populations were 178 00:10:48,559 --> 00:10:51,360 Speaker 1: they to be um uh, you know, hit by a 179 00:10:51,440 --> 00:10:56,960 Speaker 1: nuclear attack. So that's kind of what spawned this idea 180 00:10:56,960 --> 00:11:00,760 Speaker 1: of the Strategic Defense initiative. And you have you actually 181 00:11:00,840 --> 00:11:04,680 Speaker 1: looked at the the announcement that kind of unveiled this 182 00:11:04,720 --> 00:11:09,920 Speaker 1: to the world, right, Um, yeah, I. And in doing 183 00:11:09,920 --> 00:11:11,960 Speaker 1: the research for this this you can actually date the 184 00:11:11,960 --> 00:11:17,000 Speaker 1: Strategic Defense Initiative back to a specific date, although really 185 00:11:17,040 --> 00:11:21,000 Speaker 1: the idea goes back farther. But when people picking a 186 00:11:21,000 --> 00:11:24,400 Speaker 1: a significant date in the history of the s D, 187 00:11:24,559 --> 00:11:29,840 Speaker 1: I uh most pick March when President uh Ronald Reagan 188 00:11:30,000 --> 00:11:33,920 Speaker 1: addressed the country on issues of national security. Now, UM, 189 00:11:33,960 --> 00:11:37,560 Speaker 1: a while back, I actually had found a series of 190 00:11:37,600 --> 00:11:42,040 Speaker 1: podcasts on presidents that were being offered by UM, I 191 00:11:42,080 --> 00:11:45,199 Speaker 1: believe PBS. They were free, so I downloaded and watched 192 00:11:45,240 --> 00:11:47,679 Speaker 1: several of them, and I kind of, um, you know, 193 00:11:48,040 --> 00:11:50,920 Speaker 1: Reagan's term two terms were during my lifetime, but I 194 00:11:50,920 --> 00:11:53,280 Speaker 1: don't remember a lot about about him and what he 195 00:11:53,320 --> 00:11:56,000 Speaker 1: was like. And I, from what I understand, he you know, 196 00:11:56,040 --> 00:11:57,760 Speaker 1: although I think a lot of people see him a 197 00:11:57,840 --> 00:12:01,320 Speaker 1: sort of a a militarist in some respects because he 198 00:12:01,360 --> 00:12:03,480 Speaker 1: did he did stress in this message you know, look 199 00:12:03,520 --> 00:12:05,400 Speaker 1: we can't We've got to be tough. We want to 200 00:12:05,440 --> 00:12:08,480 Speaker 1: deter our enemies. But UM, I think he was also 201 00:12:09,320 --> 00:12:11,440 Speaker 1: he he kind of didn't like this stress. From what 202 00:12:11,480 --> 00:12:14,040 Speaker 1: I understand, he the stress that that brings on, because 203 00:12:14,120 --> 00:12:17,480 Speaker 1: it's a stressful environment. You're always wondering if you have 204 00:12:17,600 --> 00:12:21,520 Speaker 1: more weapons than the other people, if your arms cash is, 205 00:12:21,559 --> 00:12:24,079 Speaker 1: if you have more more soldiers and sailors and marines. 206 00:12:24,720 --> 00:12:28,200 Speaker 1: Looking at looking at uh as stressful. Yeah, you start 207 00:12:28,280 --> 00:12:30,920 Speaker 1: looking at statistics like if we were hit by a 208 00:12:30,960 --> 00:12:34,119 Speaker 1: first strike, how many of our weapons would remain operable 209 00:12:34,200 --> 00:12:36,480 Speaker 1: so that we could strike back. I mean, when you're 210 00:12:36,559 --> 00:12:40,000 Speaker 1: looking at that scenario, you're already saying, we've been hit 211 00:12:40,160 --> 00:12:44,520 Speaker 1: and we've lost a massive amount of our infrastructure, our citizens, 212 00:12:45,360 --> 00:12:49,719 Speaker 1: We've taken huge losses. Can we strike back? I mean, 213 00:12:49,720 --> 00:12:51,800 Speaker 1: when you when you have to ask yourself that question, 214 00:12:51,920 --> 00:12:54,400 Speaker 1: that is, I mean, that's a tough question because you're 215 00:12:54,440 --> 00:12:57,840 Speaker 1: already talking about defeat in a way, no one wins 216 00:12:57,880 --> 00:13:02,480 Speaker 1: in that situation, right right, right? So um he uh 217 00:13:02,559 --> 00:13:06,400 Speaker 1: And in this particular speech wasn't particularly long address, um, 218 00:13:06,600 --> 00:13:10,400 Speaker 1: but this was Yeah, it's not very long, and it's 219 00:13:10,440 --> 00:13:13,679 Speaker 1: easy to find, but it's kind of interesting because it 220 00:13:13,679 --> 00:13:17,440 Speaker 1: takes a different tack, if you will. Um basically said, look, 221 00:13:17,480 --> 00:13:20,600 Speaker 1: I want to offer you a different idea, an idea 222 00:13:20,640 --> 00:13:24,120 Speaker 1: that might bring you hope. Rather than trying to destroy 223 00:13:24,240 --> 00:13:28,720 Speaker 1: our enemies outright necessarily, why don't we embark on a 224 00:13:28,800 --> 00:13:33,720 Speaker 1: plan to uh to intercept and destroy these weapons before 225 00:13:33,720 --> 00:13:36,520 Speaker 1: they reach us? And that means we don't necessarily have 226 00:13:36,679 --> 00:13:39,959 Speaker 1: we can we can focus instead on protecting ourselves rather 227 00:13:40,000 --> 00:13:45,080 Speaker 1: than destroying our enemies. Um. Although to be sure, I'm 228 00:13:45,080 --> 00:13:49,040 Speaker 1: sure that he wanted to rely on uh mutually to 229 00:13:49,080 --> 00:13:51,559 Speaker 1: assure destruction to some degree as a defense initiative. And 230 00:13:51,600 --> 00:13:53,440 Speaker 1: I think, you know, frankly, you could argue that it 231 00:13:53,480 --> 00:13:56,720 Speaker 1: does have some value. But you know, he said, look, 232 00:13:56,880 --> 00:13:59,440 Speaker 1: let's instead of doing this, let's do something new and used. 233 00:13:59,480 --> 00:14:01,720 Speaker 1: We've got a lot of technology available to us to 234 00:14:01,800 --> 00:14:06,080 Speaker 1: make sophisticated weapons and defense systems. Let's create a network 235 00:14:06,240 --> 00:14:10,640 Speaker 1: of defenses that will intercept and destroy nuclear weapons before 236 00:14:10,640 --> 00:14:14,280 Speaker 1: they could actually reach us. UM. And you know, he 237 00:14:14,280 --> 00:14:16,199 Speaker 1: doesn't really get into a lot of the details in 238 00:14:16,240 --> 00:14:20,160 Speaker 1: the address, so that that comes later. And although although 239 00:14:20,200 --> 00:14:21,840 Speaker 1: I think it, I think it only took the next 240 00:14:21,920 --> 00:14:24,800 Speaker 1: day before someone called it the star Wars program. Yeah, 241 00:14:24,800 --> 00:14:27,720 Speaker 1: it didn't, because you know, there are a lot of 242 00:14:27,800 --> 00:14:30,040 Speaker 1: pieces to it, and it's a lot of it is 243 00:14:30,080 --> 00:14:34,240 Speaker 1: about you know, weaponizing space espentially essentially, you know, where 244 00:14:34,240 --> 00:14:36,400 Speaker 1: you're saying, let's put stuff in the sky that can 245 00:14:36,400 --> 00:14:40,000 Speaker 1: shoot other stuff out of the sky and um, but 246 00:14:40,080 --> 00:14:42,960 Speaker 1: it's not just about that. There were ground defenses, there 247 00:14:42,960 --> 00:14:46,440 Speaker 1: were airborne defenses, there were space born defenses, all as 248 00:14:46,480 --> 00:14:50,360 Speaker 1: part of this overall network and uh it's not even 249 00:14:50,400 --> 00:14:54,840 Speaker 1: that simple because it's shifted over time to mean different 250 00:14:54,880 --> 00:14:58,520 Speaker 1: things during different presidents and different departments took over parts 251 00:14:58,560 --> 00:15:01,360 Speaker 1: of the of the What was originally all part of 252 00:15:01,360 --> 00:15:04,680 Speaker 1: the Strategic Defense Initiative, some of that broke off and became, 253 00:15:05,240 --> 00:15:09,640 Speaker 1: uh specifically an Air Force initiative, so it was no 254 00:15:09,680 --> 00:15:13,720 Speaker 1: longer part of s d I. It was a different program. 255 00:15:13,800 --> 00:15:17,520 Speaker 1: Um and uh so so yeah, I mean it's it's 256 00:15:17,600 --> 00:15:19,480 Speaker 1: kind of you think about it. How are you going 257 00:15:19,560 --> 00:15:21,840 Speaker 1: to do that? How are you going to stop missiles 258 00:15:21,880 --> 00:15:25,280 Speaker 1: before they even you know, come down and hit the earth. 259 00:15:25,440 --> 00:15:28,200 Speaker 1: And there were a lot of proposals, so it seems 260 00:15:29,000 --> 00:15:33,680 Speaker 1: pardon the not pun but weird pun like thing, uh 261 00:15:33,960 --> 00:15:36,560 Speaker 1: pie in the sky sort of thing. Yeah, um so 262 00:15:36,640 --> 00:15:38,960 Speaker 1: I am thinking of a giant pie stopping missiles. But yeah, 263 00:15:39,440 --> 00:15:41,640 Speaker 1: how are you going to spend money on that's going 264 00:15:41,680 --> 00:15:46,640 Speaker 1: to do this? Yeah, I've lost him so uh so, yeah, 265 00:15:46,680 --> 00:15:48,960 Speaker 1: it was it was supposed to stop i c b 266 00:15:49,240 --> 00:15:54,080 Speaker 1: ms from reaching the United States. Now, part of it was, hey, 267 00:15:54,120 --> 00:15:55,840 Speaker 1: if you can destroy it in space before it even 268 00:15:55,840 --> 00:15:58,360 Speaker 1: reenters the atmosphere, because you know, some i c b 269 00:15:58,560 --> 00:16:02,440 Speaker 1: ms do they reach a low orbit and then at 270 00:16:02,480 --> 00:16:04,360 Speaker 1: their at their peak, they are in a low orbit 271 00:16:04,400 --> 00:16:08,160 Speaker 1: and then they re enter on a trajectory towards their target. Yes, 272 00:16:08,400 --> 00:16:11,720 Speaker 1: that's why they're intercontinental UM. But yes, there are other 273 00:16:11,760 --> 00:16:16,640 Speaker 1: weapons that don't reach that that altitude UM. And it's 274 00:16:16,680 --> 00:16:19,240 Speaker 1: interesting because if you look at the history and the 275 00:16:19,320 --> 00:16:22,880 Speaker 1: various proposals that were all part of s d I, 276 00:16:23,080 --> 00:16:25,400 Speaker 1: you start to realize that they were figuring this out 277 00:16:25,440 --> 00:16:27,560 Speaker 1: as they were going along as well, like there were 278 00:16:27,640 --> 00:16:31,000 Speaker 1: the Originally, a lot of the idea was that, well, 279 00:16:31,040 --> 00:16:32,880 Speaker 1: we can as long as we can shoot down the 280 00:16:32,920 --> 00:16:37,040 Speaker 1: missile or destroy the missile before it before it gets 281 00:16:37,480 --> 00:16:40,600 Speaker 1: uh you know, before it makes contact, then that's acceptable. 282 00:16:40,920 --> 00:16:44,120 Speaker 1: Except for the fact that there was the discovery of hey, uh, 283 00:16:44,160 --> 00:16:49,600 Speaker 1: these these blasts are releasing gig enormous electromagnetic pulses or 284 00:16:49,640 --> 00:16:52,520 Speaker 1: e m p s, and that means that were you 285 00:16:52,600 --> 00:16:56,000 Speaker 1: to detonate a nuclear weapon, even at a fairly high 286 00:16:56,040 --> 00:16:59,480 Speaker 1: altitude over the United States, that e MP could end 287 00:16:59,560 --> 00:17:03,400 Speaker 1: up affecting the electronics on the ground or even in 288 00:17:03,440 --> 00:17:05,280 Speaker 1: the air. So you're talking about all the airplanes that 289 00:17:05,359 --> 00:17:07,879 Speaker 1: maybe in the area, you're talking about all the electronics 290 00:17:07,880 --> 00:17:09,639 Speaker 1: in the area of like the power grid in the area. 291 00:17:09,680 --> 00:17:13,440 Speaker 1: It could create blackouts in over a massive range because 292 00:17:13,480 --> 00:17:16,440 Speaker 1: I mean a big enough EMP could put a load 293 00:17:16,480 --> 00:17:19,960 Speaker 1: not just on that region's power grid, but the neighboring 294 00:17:19,960 --> 00:17:23,879 Speaker 1: regions as well. So, uh, you know, we we did 295 00:17:23,960 --> 00:17:26,359 Speaker 1: an entire podcast about e m p s in the past, 296 00:17:26,400 --> 00:17:27,959 Speaker 1: so if you if you really want to know more 297 00:17:27,960 --> 00:17:30,000 Speaker 1: about them, I recommend you check that out because it 298 00:17:30,080 --> 00:17:33,880 Speaker 1: is it's interesting tactic as well as just a side 299 00:17:33,880 --> 00:17:37,399 Speaker 1: effect of the nuclear war arms program in the first place. 300 00:17:37,840 --> 00:17:41,760 Speaker 1: So that kind of led to discussions about, well, what 301 00:17:41,800 --> 00:17:45,239 Speaker 1: we really need our defense initiatives that would allow us 302 00:17:45,280 --> 00:17:49,040 Speaker 1: to shoot down missiles as as close to when they 303 00:17:49,119 --> 00:17:54,040 Speaker 1: launch as possible and um and to be perfectly clear, 304 00:17:54,080 --> 00:17:56,000 Speaker 1: I mean, if you go to the Department of Defense, 305 00:17:56,359 --> 00:18:00,680 Speaker 1: they have unclassified documents, lots of them, lots of them 306 00:18:00,680 --> 00:18:03,160 Speaker 1: that you can read. And there's one that's uh that's 307 00:18:03,320 --> 00:18:06,440 Speaker 1: a memorandum for the Secretary of Defense that is the 308 00:18:06,520 --> 00:18:10,719 Speaker 1: Space component of US Military Strategy and war Fighting Requirements 309 00:18:10,720 --> 00:18:15,119 Speaker 1: for US Military Space Systems. That document makes it very 310 00:18:15,160 --> 00:18:19,920 Speaker 1: clear they're talking specifically about the Soviets. The term Soviets 311 00:18:19,960 --> 00:18:24,479 Speaker 1: appears multiple times through this document, which is several pages long, 312 00:18:24,560 --> 00:18:28,040 Speaker 1: is written in n so you know there was there 313 00:18:28,040 --> 00:18:30,760 Speaker 1: were no illusions. This was not you know, some sort 314 00:18:30,800 --> 00:18:34,960 Speaker 1: of vague defense system that was meant to protect the 315 00:18:35,000 --> 00:18:38,160 Speaker 1: United States from any attacker. This was something that was 316 00:18:38,359 --> 00:18:42,400 Speaker 1: that was talked about with the Soviets in mind in particular. Um, 317 00:18:42,600 --> 00:18:45,920 Speaker 1: so part of that was talking about you know, we mentioned, 318 00:18:46,040 --> 00:18:47,840 Speaker 1: or you mentioned, Chris, that there were going to be 319 00:18:47,880 --> 00:18:50,399 Speaker 1: ground based systems as well as ones in space and 320 00:18:50,480 --> 00:18:53,600 Speaker 1: in the air. Uh. This this meant that your ground 321 00:18:53,600 --> 00:18:56,680 Speaker 1: based systems were essentially things like radar stations where you 322 00:18:56,680 --> 00:19:00,800 Speaker 1: can detect that missile had had launched, because as missiles 323 00:19:00,840 --> 00:19:02,720 Speaker 1: were going at altitudes that were high enough to be 324 00:19:02,760 --> 00:19:07,920 Speaker 1: detectable by radar. The the space element eventually came to 325 00:19:08,000 --> 00:19:10,440 Speaker 1: the conclusion that there needed to be satellites that would 326 00:19:10,440 --> 00:19:13,040 Speaker 1: be positioned directly over the Soviet Union in order for 327 00:19:13,080 --> 00:19:15,600 Speaker 1: this to be effective, so that we could launch a 328 00:19:15,760 --> 00:19:20,920 Speaker 1: counter measure from space to interfere with the I, C, B, 329 00:19:21,160 --> 00:19:26,560 Speaker 1: M S. And UM, you know, there were several systems 330 00:19:26,560 --> 00:19:29,720 Speaker 1: that we're going to rely on one of your favorite 331 00:19:29,960 --> 00:19:34,920 Speaker 1: technologies lasers. Actually, I would I would argue at least 332 00:19:35,320 --> 00:19:37,000 Speaker 1: I don't know about you, Chris, when I was a 333 00:19:37,080 --> 00:19:41,240 Speaker 1: kid in the eighties, my perception, and granted, remember I 334 00:19:41,280 --> 00:19:43,400 Speaker 1: was a kid, I only I only knew about this 335 00:19:43,480 --> 00:19:46,600 Speaker 1: kind of because adults talked about it, right, But as 336 00:19:46,640 --> 00:19:49,520 Speaker 1: a kid, I always imagined that the Star Wars program 337 00:19:49,560 --> 00:19:53,000 Speaker 1: was all about lasers. I never, I never knew as 338 00:19:53,040 --> 00:19:55,040 Speaker 1: a kid during the time when this was actually happening 339 00:19:55,080 --> 00:19:58,600 Speaker 1: that that was just one of many proposals. But to 340 00:19:58,640 --> 00:20:01,080 Speaker 1: talk about the lasers, the system them that was proposed, 341 00:20:01,080 --> 00:20:05,119 Speaker 1: the initial one with X ray lasers was really really 342 00:20:05,280 --> 00:20:10,920 Speaker 1: kind of interesting, and ultimately people like scientists and and 343 00:20:11,040 --> 00:20:13,840 Speaker 1: military personnel determined that it was not feasible. But the 344 00:20:13,920 --> 00:20:18,160 Speaker 1: idea was that you would launch satellites into orbit position 345 00:20:18,240 --> 00:20:22,119 Speaker 1: them over the Soviet Union. These satellites would actually contain 346 00:20:22,320 --> 00:20:27,160 Speaker 1: a nuclear warhead inside the satellite. The satellite would also 347 00:20:27,240 --> 00:20:30,639 Speaker 1: contain lazing material. You might want to go back and 348 00:20:30,680 --> 00:20:35,040 Speaker 1: listen to our Laser's podcast to hear about lazing material. 349 00:20:35,359 --> 00:20:38,720 Speaker 1: But that the nuclear explosion when you when you detonated 350 00:20:38,760 --> 00:20:42,280 Speaker 1: the warhead would provide the energy that would emit an 351 00:20:42,280 --> 00:20:46,080 Speaker 1: extremely powerful X ray laser using this lazing material, and 352 00:20:46,080 --> 00:20:48,560 Speaker 1: that you would include lots and lots of lasers in 353 00:20:48,600 --> 00:20:51,080 Speaker 1: a in a single satellite, like two dozen of them 354 00:20:51,119 --> 00:20:53,400 Speaker 1: in there, so that they could shoot down multiple targets 355 00:20:54,080 --> 00:20:59,000 Speaker 1: from one detonation. I believe at the time UH the 356 00:20:59,119 --> 00:21:03,000 Speaker 1: United States had estimated that the Soviet Union had lots 357 00:21:03,000 --> 00:21:05,800 Speaker 1: and lots of warheads, but only I think fewer than 358 00:21:05,840 --> 00:21:09,040 Speaker 1: two thousand actual missiles. So the idea was that you 359 00:21:09,040 --> 00:21:12,240 Speaker 1: had to have enough satellites to shoot down the majority 360 00:21:12,320 --> 00:21:15,639 Speaker 1: of those two thousand or so or fewer missiles in 361 00:21:15,760 --> 00:21:20,159 Speaker 1: order to protect the United States. So in order to 362 00:21:20,200 --> 00:21:22,199 Speaker 1: shoot them down, you would have to detonate a nuclear 363 00:21:22,240 --> 00:21:25,080 Speaker 1: warhead within this satellite and have it contained in such 364 00:21:25,080 --> 00:21:30,320 Speaker 1: a way that the energy is then UH directed into 365 00:21:30,480 --> 00:21:33,000 Speaker 1: a lasing medium shoots an X ray laser. The X 366 00:21:33,080 --> 00:21:37,120 Speaker 1: ray laser hits the missile and UH and shoots it down. 367 00:21:38,080 --> 00:21:39,280 Speaker 1: And to do that, of course, you also have to 368 00:21:39,320 --> 00:21:40,840 Speaker 1: have a tracking system. You have to figure out how 369 00:21:40,880 --> 00:21:44,200 Speaker 1: you're gonna track it. Originally I think they were looking 370 00:21:44,280 --> 00:21:47,840 Speaker 1: at um at at radar, but then there was the 371 00:21:47,880 --> 00:21:54,000 Speaker 1: possibility of having of the Soviet Union launching decoys using 372 00:21:54,200 --> 00:21:58,240 Speaker 1: radar reflectors so that the radar would have false readings saying, oh, 373 00:21:58,440 --> 00:22:01,240 Speaker 1: here's a missile over here, and by shooting lots and 374 00:22:01,240 --> 00:22:02,920 Speaker 1: lots of these up in the air all at once, 375 00:22:03,400 --> 00:22:05,320 Speaker 1: it would mean you would waste a lot of your 376 00:22:05,400 --> 00:22:10,920 Speaker 1: your defense initiative shooting down dummies essentially. There was also 377 00:22:10,960 --> 00:22:15,280 Speaker 1: a talk about using UH sensors that would detect heat signatures, 378 00:22:15,600 --> 00:22:17,919 Speaker 1: and you would see the heat signature from a missile 379 00:22:17,960 --> 00:22:20,480 Speaker 1: is going to be much larger than a decoy, So 380 00:22:20,520 --> 00:22:22,919 Speaker 1: then you just aim for the big ones, right, But 381 00:22:23,000 --> 00:22:25,719 Speaker 1: this is not this is a non trivial problem figuring 382 00:22:25,760 --> 00:22:28,160 Speaker 1: out not just how to make the laser work, which 383 00:22:28,200 --> 00:22:30,919 Speaker 1: by the way, no one really ever figured out a 384 00:22:31,040 --> 00:22:34,639 Speaker 1: reliable way of doing that, but figuring out the targeting 385 00:22:34,680 --> 00:22:38,439 Speaker 1: system so that you can look reliably target and shoot 386 00:22:38,480 --> 00:22:41,520 Speaker 1: down these missiles without missing them, because that energy is 387 00:22:41,520 --> 00:22:44,439 Speaker 1: gonna keep on going. If you miss that missile, it's 388 00:22:44,440 --> 00:22:48,280 Speaker 1: going to hit something else. Stupid physics. Yeah, and we're 389 00:22:48,280 --> 00:22:50,840 Speaker 1: talking X ray lasers. I mean this, this is really 390 00:22:51,280 --> 00:22:53,840 Speaker 1: X ray lasers powered by a nuclear explosion. This is 391 00:22:53,920 --> 00:22:57,760 Speaker 1: a very powerful beam of light. And then you have 392 00:22:57,880 --> 00:23:02,120 Speaker 1: you know, the brilliant pebbles. Alliant pebbles, yes, which were 393 00:23:02,160 --> 00:23:07,040 Speaker 1: the UH basically autonomous spacecraft. Yes, you know, just sort 394 00:23:07,040 --> 00:23:09,280 Speaker 1: of coasting around it. They're looking for stuff to shoot 395 00:23:09,280 --> 00:23:12,440 Speaker 1: down or collide with. Yeah, a lot of it was 396 00:23:12,440 --> 00:23:15,320 Speaker 1: was kind of the idea of not necessarily even shooting 397 00:23:15,359 --> 00:23:18,320 Speaker 1: something down, but just putting something in the way of 398 00:23:18,359 --> 00:23:21,119 Speaker 1: the missile so that it would, uh, it would end 399 00:23:21,200 --> 00:23:24,040 Speaker 1: up destroying itself or falling to the Earth, you know, 400 00:23:24,160 --> 00:23:27,560 Speaker 1: something like that, where you're not you're not necessarily trying 401 00:23:27,560 --> 00:23:30,600 Speaker 1: to destroy the missile in mid air. UM. There were 402 00:23:30,680 --> 00:23:34,600 Speaker 1: several missile systems that were proposed where you would actually 403 00:23:34,880 --> 00:23:38,320 Speaker 1: shoot a missile from space to the I, C. B 404 00:23:38,560 --> 00:23:40,680 Speaker 1: M to destroy it, and the idea being that you 405 00:23:40,680 --> 00:23:44,119 Speaker 1: wouldn't need as much fuel for the individual missiles or 406 00:23:44,200 --> 00:23:46,920 Speaker 1: rockets or whatever you want to call them, um in 407 00:23:46,960 --> 00:23:50,920 Speaker 1: the in the satellites that would be housing these weapons systems, 408 00:23:51,000 --> 00:23:53,479 Speaker 1: because they don't have to escape the Earth's gravity. They 409 00:23:53,520 --> 00:23:57,760 Speaker 1: just have to be aimed at the right direction and fired. Uh. 410 00:23:57,800 --> 00:24:00,679 Speaker 1: Some of them were would have tracking ability so that 411 00:24:00,720 --> 00:24:04,119 Speaker 1: they could change direction in midflight. I saw proposals for 412 00:24:04,160 --> 00:24:07,600 Speaker 1: a rail gun system. Railguns, in case you were wondering, 413 00:24:07,760 --> 00:24:13,760 Speaker 1: use electromagnetic energy to propel a a projectile down a pathway, 414 00:24:14,080 --> 00:24:16,080 Speaker 1: so you're actually it's the same sort of thing like 415 00:24:16,160 --> 00:24:20,520 Speaker 1: UM particle accelerators. Right, with a particle accelerator, for example, 416 00:24:20,560 --> 00:24:25,200 Speaker 1: the large hadron collider, you wanna accelerate a proton beam 417 00:24:25,440 --> 00:24:27,760 Speaker 1: faster and faster and faster around the circle until it 418 00:24:27,800 --> 00:24:30,040 Speaker 1: reaches the right speed where you make it collide with 419 00:24:30,080 --> 00:24:32,520 Speaker 1: another proton being traveling at the same speed but in 420 00:24:32,520 --> 00:24:36,760 Speaker 1: the opposite direction. You do that by using magnetic force, 421 00:24:36,800 --> 00:24:39,919 Speaker 1: because you know, protons are positively charged, so you use 422 00:24:39,960 --> 00:24:42,240 Speaker 1: a negative charge ahead of the proton to pull it, 423 00:24:42,440 --> 00:24:44,800 Speaker 1: or a positive charge behind the proton to push it, 424 00:24:45,280 --> 00:24:48,119 Speaker 1: and you just you increase that frequency until it's moving 425 00:24:48,160 --> 00:24:50,760 Speaker 1: at near the speed of light. Well, the railguns work 426 00:24:50,760 --> 00:24:54,240 Speaker 1: on a similar idea, except you're using a physical projectile 427 00:24:54,960 --> 00:24:59,520 Speaker 1: and you're using electromagnetic energy to to shoot the projectile 428 00:24:59,520 --> 00:25:02,600 Speaker 1: out of the system. The big problem there was that 429 00:25:02,680 --> 00:25:07,840 Speaker 1: even though it was possible to make a railgun UM 430 00:25:07,840 --> 00:25:12,440 Speaker 1: at the time it was, they could only fire infrequently, 431 00:25:12,600 --> 00:25:15,560 Speaker 1: like we're talking like once a day or once every 432 00:25:15,600 --> 00:25:18,720 Speaker 1: couple of weeks, because it just took so much energy 433 00:25:18,760 --> 00:25:21,240 Speaker 1: to generate that and to make it work that you 434 00:25:21,280 --> 00:25:24,440 Speaker 1: couldn't just reload and fire and fire and fire UM. 435 00:25:24,560 --> 00:25:26,160 Speaker 1: So in order for that system to work, it would 436 00:25:26,160 --> 00:25:28,119 Speaker 1: of course have to be able to fire lots of 437 00:25:28,160 --> 00:25:30,840 Speaker 1: times in a in a short time frame. You'd also 438 00:25:30,880 --> 00:25:32,320 Speaker 1: have to figure out, all right, well, what kind of 439 00:25:32,320 --> 00:25:34,320 Speaker 1: projectile are we using. We have to have one that 440 00:25:34,600 --> 00:25:37,240 Speaker 1: if we're shooting it from space, the projectile has to 441 00:25:37,240 --> 00:25:40,440 Speaker 1: be able to survive re entry into the Earth's atmosphere, 442 00:25:40,920 --> 00:25:42,959 Speaker 1: and so that there were a lot of problems with that. 443 00:25:43,040 --> 00:25:47,520 Speaker 1: So we were talking about missile systems, projectile systems, laser systems. 444 00:25:47,680 --> 00:25:51,520 Speaker 1: There were even systems that projects that suggested nets like 445 00:25:51,880 --> 00:25:54,680 Speaker 1: either missiles that would deploy a net that would foul 446 00:25:54,760 --> 00:25:56,679 Speaker 1: and I C B M and cause it to to 447 00:25:56,960 --> 00:26:02,440 Speaker 1: not uh too well to detonate essentially m m um. 448 00:26:02,480 --> 00:26:05,600 Speaker 1: And the more we looked into this, and we being 449 00:26:05,720 --> 00:26:09,200 Speaker 1: scientists and engineers, the more it appeared that, at least 450 00:26:09,320 --> 00:26:13,160 Speaker 1: based on the nineteen eighties technology and even nineteen nineties technology, 451 00:26:13,200 --> 00:26:16,480 Speaker 1: this did span more than a decade um and in fact, 452 00:26:16,600 --> 00:26:18,840 Speaker 1: some of the elements are still in place in the 453 00:26:18,880 --> 00:26:24,600 Speaker 1: in the United States military. Uh. It just became clear 454 00:26:24,760 --> 00:26:27,880 Speaker 1: that there was no easy or feasible or cost effective 455 00:26:27,880 --> 00:26:30,679 Speaker 1: way of deploying this. You know, you eventually had to 456 00:26:30,720 --> 00:26:32,439 Speaker 1: come to the conclusion of does it make sense to 457 00:26:32,480 --> 00:26:36,520 Speaker 1: pour billions and billions of dollars or, as Karl Sagan 458 00:26:36,560 --> 00:26:41,320 Speaker 1: would put it, billions and billions of dollars into a 459 00:26:41,320 --> 00:26:45,080 Speaker 1: program that you might not ever use right right, And 460 00:26:45,480 --> 00:26:48,399 Speaker 1: the it did receive some initial funding from Congress. I 461 00:26:48,400 --> 00:26:51,080 Speaker 1: mean back in the nineteen eighties, people were behind the 462 00:26:51,119 --> 00:26:55,359 Speaker 1: idea and and you know, jumped on the chance to 463 00:26:55,359 --> 00:27:00,240 Speaker 1: to fund this project. But I mean, immediately or seemingly 464 00:27:00,320 --> 00:27:03,520 Speaker 1: immediately out of the gate, there were people criticizing the 465 00:27:03,600 --> 00:27:09,440 Speaker 1: ideas being too expensive, too difficult to pardon upon otherworldly 466 00:27:09,560 --> 00:27:11,680 Speaker 1: It's like, how are we you know, this is foreign 467 00:27:11,760 --> 00:27:14,600 Speaker 1: to us. And it earned you know, it earned the 468 00:27:14,640 --> 00:27:18,600 Speaker 1: program the nickname, you know, Star Wars. It earned Reagan 469 00:27:18,600 --> 00:27:22,000 Speaker 1: the nickname Ronnie Rey gun Well. And and you know, 470 00:27:22,640 --> 00:27:24,760 Speaker 1: not only did it seem like it was unlikely to happen, 471 00:27:24,880 --> 00:27:26,880 Speaker 1: but there were people who are saying, if we did 472 00:27:26,920 --> 00:27:31,639 Speaker 1: have this in place, it would actually potentially lead to 473 00:27:31,800 --> 00:27:36,240 Speaker 1: a nuclear war, because because you would either that either 474 00:27:36,359 --> 00:27:39,320 Speaker 1: the side that has the technology would say, hey, now 475 00:27:39,359 --> 00:27:41,879 Speaker 1: we have the advantage. We can launch an initial attack 476 00:27:41,920 --> 00:27:44,679 Speaker 1: against our enemy, and we have the defenses in place 477 00:27:44,720 --> 00:27:47,600 Speaker 1: to prevent most of their missiles coming over here, So 478 00:27:47,640 --> 00:27:49,600 Speaker 1: we should just wipe them out because we can do 479 00:27:49,680 --> 00:27:52,439 Speaker 1: it now. And then the other side of the argument 480 00:27:52,520 --> 00:27:55,600 Speaker 1: is the the enemy. The Soviets could say, hey, they're 481 00:27:55,640 --> 00:27:58,920 Speaker 1: putting this this defense initiative in place. If we don't 482 00:27:58,960 --> 00:28:01,959 Speaker 1: attack now, we're going to be at a weekend position. 483 00:28:02,000 --> 00:28:05,320 Speaker 1: So we should attack before they get the defense system up. Yes, 484 00:28:05,520 --> 00:28:08,160 Speaker 1: and then you you have your you actually end up 485 00:28:08,320 --> 00:28:13,040 Speaker 1: causing the very event you're trying to prevent. Yes, And 486 00:28:13,080 --> 00:28:16,639 Speaker 1: the Soviets were working on their own version of the system. 487 00:28:16,680 --> 00:28:20,320 Speaker 1: It it escalated tensions in the Cold War because suddenly 488 00:28:20,359 --> 00:28:25,040 Speaker 1: we were embarking on this new project. That UM was 489 00:28:25,160 --> 00:28:28,399 Speaker 1: very scary because all of a sudden, and and Reagan 490 00:28:28,480 --> 00:28:30,480 Speaker 1: was right in that it does take some of the 491 00:28:30,560 --> 00:28:33,440 Speaker 1: sting out of the mutually assured destruction. So all of 492 00:28:33,480 --> 00:28:36,639 Speaker 1: a sudden, they're going, wait a minute, that's what we 493 00:28:36,680 --> 00:28:40,000 Speaker 1: can shoot at them. And then once they neutralize all 494 00:28:40,040 --> 00:28:43,080 Speaker 1: our weapons or most of our weapons, they can shoot back, 495 00:28:43,360 --> 00:28:45,000 Speaker 1: or they can shoot at us before we can even 496 00:28:45,040 --> 00:28:47,000 Speaker 1: shoot at them, and then they shoot all our stuff 497 00:28:47,000 --> 00:28:51,840 Speaker 1: down for us. Yes, So that that escalated tensions just 498 00:28:51,960 --> 00:28:56,520 Speaker 1: that much more. UM. But UH, and and the Soviets 499 00:28:56,520 --> 00:28:59,240 Speaker 1: were working on their own system, which came to light 500 00:28:59,360 --> 00:29:02,000 Speaker 1: years later. But and there were there were scientists and 501 00:29:02,040 --> 00:29:05,120 Speaker 1: engineers who argued even at the beginning that really the 502 00:29:05,160 --> 00:29:08,360 Speaker 1: answer to this was not building an SDI system, but 503 00:29:08,680 --> 00:29:13,240 Speaker 1: using diplomacy to try and and UH in the Cold 504 00:29:13,440 --> 00:29:15,959 Speaker 1: Cold War, and as we know, that eventually did happen, 505 00:29:16,280 --> 00:29:18,120 Speaker 1: although you could argue that we're in a new Cold 506 00:29:18,160 --> 00:29:21,720 Speaker 1: War now UM or at least the beginning stages of one. 507 00:29:22,320 --> 00:29:27,160 Speaker 1: The but the diplomacy was what several people had advocated for. 508 00:29:27,800 --> 00:29:30,520 Speaker 1: And actually that when that started to work, when the 509 00:29:30,560 --> 00:29:33,720 Speaker 1: Cold War began to kind of unravel, that that was 510 00:29:34,040 --> 00:29:37,480 Speaker 1: bad news for the SDI initiative, which, by the way, 511 00:29:37,560 --> 00:29:40,160 Speaker 1: it underwent several name changes. I'm just going to say 512 00:29:40,200 --> 00:29:42,040 Speaker 1: SDI because it's easier. I don't want to cop on 513 00:29:42,480 --> 00:29:45,360 Speaker 1: going back and forth. But it meant that UM, getting 514 00:29:45,400 --> 00:29:48,120 Speaker 1: funding for those programs was more and more difficult because 515 00:29:48,160 --> 00:29:50,400 Speaker 1: there seemed to be less of a need for one. 516 00:29:50,480 --> 00:29:55,280 Speaker 1: You started to have nuclear disarmament disarmament programs, which you 517 00:29:55,320 --> 00:30:00,600 Speaker 1: know that that decreased the need for a space warfare initiative. UH. 518 00:30:00,720 --> 00:30:03,600 Speaker 1: Some of those elements though still got funding and continued 519 00:30:03,640 --> 00:30:07,080 Speaker 1: to UH to be an important part in military strategy. 520 00:30:07,080 --> 00:30:09,720 Speaker 1: I mean a lot of our our spy satellites came 521 00:30:09,760 --> 00:30:13,800 Speaker 1: out of that program, and we've developed sensors and GPS 522 00:30:13,880 --> 00:30:16,880 Speaker 1: systems that were initially in one way or another tied 523 00:30:16,960 --> 00:30:20,800 Speaker 1: into sd I, and we've benefited from those. So not 524 00:30:20,920 --> 00:30:25,800 Speaker 1: everything in s d I was um impossible or are 525 00:30:25,800 --> 00:30:30,520 Speaker 1: are too expensive or unnecessary? Right right, And some of 526 00:30:30,560 --> 00:30:33,880 Speaker 1: it does, you know, have clear application. Now I should 527 00:30:33,880 --> 00:30:36,600 Speaker 1: point out I was curious about the GPS connection, and 528 00:30:36,640 --> 00:30:40,959 Speaker 1: GPS did exist in forms before sd I, so but 529 00:30:41,280 --> 00:30:44,000 Speaker 1: you know, the fact of the matter is the GPS 530 00:30:44,080 --> 00:30:47,440 Speaker 1: system is really very necessary to make something like sd 531 00:30:47,520 --> 00:30:50,320 Speaker 1: I work, you wherever to do that. Also, it spawned 532 00:30:50,360 --> 00:30:55,600 Speaker 1: a game for the Amiga called s d I, which 533 00:30:55,680 --> 00:30:59,240 Speaker 1: is very much about what this would have been about 534 00:30:59,280 --> 00:31:02,560 Speaker 1: if you could just make it happen, also Missile Commander. 535 00:31:05,200 --> 00:31:07,440 Speaker 1: And we should point out that some of this, some 536 00:31:07,520 --> 00:31:10,280 Speaker 1: of the philosophies here have been used in in a 537 00:31:10,400 --> 00:31:16,080 Speaker 1: smaller UH capacity, Like instead of it being a global system, 538 00:31:16,200 --> 00:31:19,000 Speaker 1: there are theater systems. And when I say theater systems, 539 00:31:19,000 --> 00:31:21,040 Speaker 1: I'm talking about the regions in which there is an 540 00:31:21,040 --> 00:31:24,800 Speaker 1: active conflict. So for example, in the initial the first 541 00:31:25,560 --> 00:31:29,360 Speaker 1: the First Gulf War, the first war in Iraq, uh, 542 00:31:29,560 --> 00:31:32,800 Speaker 1: we saw the Patriot system and the Patriot missile system 543 00:31:32,840 --> 00:31:37,440 Speaker 1: that was designed to shoot down incoming missiles anti missile missiles. Yes, 544 00:31:37,720 --> 00:31:41,040 Speaker 1: so that was that was a direct descendant from the 545 00:31:41,120 --> 00:31:44,680 Speaker 1: SDI program. It's just it was a smaller, uh, you know, 546 00:31:44,720 --> 00:31:47,640 Speaker 1: surface to air missile system as opposed to one launched 547 00:31:47,640 --> 00:31:51,920 Speaker 1: from space. But the Patriot system that came direct directly 548 00:31:52,000 --> 00:31:57,080 Speaker 1: out of the SDI initiative. And uh, another thing that 549 00:31:57,080 --> 00:31:58,680 Speaker 1: I wanted to point out is that we're at a 550 00:31:58,760 --> 00:32:00,800 Speaker 1: point now where a lot of the technology that was 551 00:32:00,800 --> 00:32:06,840 Speaker 1: talked about back in is completely feasible and possible now right, 552 00:32:06,880 --> 00:32:10,760 Speaker 1: We've we've technologically advanced to the point where but from 553 00:32:10,760 --> 00:32:14,520 Speaker 1: a hardware perspective, we could achieve many of the things 554 00:32:14,560 --> 00:32:19,200 Speaker 1: that were, um, we're proposed during the initial sd I announcement. 555 00:32:20,120 --> 00:32:23,720 Speaker 1: But there's still some some other problems, not just the 556 00:32:23,760 --> 00:32:28,400 Speaker 1: political problems and the ideological problems, but actual technical problems. 557 00:32:28,640 --> 00:32:31,640 Speaker 1: And I read an article in Time magazine. The article 558 00:32:31,680 --> 00:32:35,320 Speaker 1: was called Computers, Star Wars, and Software. It was written 559 00:32:35,320 --> 00:32:39,080 Speaker 1: in two thousand five, and in it, uh, there was 560 00:32:39,200 --> 00:32:43,400 Speaker 1: a a computer scientist named David Parnass who was a 561 00:32:43,440 --> 00:32:47,120 Speaker 1: part of a committee that worked on There was an 562 00:32:47,120 --> 00:32:51,240 Speaker 1: advisory panel for the this initiative that in time it 563 00:32:51,320 --> 00:32:54,720 Speaker 1: just refers to it as the star Wars program, and 564 00:32:54,880 --> 00:33:00,840 Speaker 1: Partners said that he he resigned from the panel our 565 00:33:00,920 --> 00:33:05,200 Speaker 1: frustration because he felt that the goals they had were 566 00:33:05,280 --> 00:33:08,440 Speaker 1: unachievable and his his perspective was that there was in 567 00:33:08,560 --> 00:33:10,760 Speaker 1: order for this system to work, to have a a 568 00:33:10,920 --> 00:33:15,080 Speaker 1: multi satellite system designed to shoot down missiles incoming missiles 569 00:33:15,600 --> 00:33:18,080 Speaker 1: meant that you would have to have a software program 570 00:33:18,200 --> 00:33:21,200 Speaker 1: so complex it would be the largest and most complex 571 00:33:21,240 --> 00:33:23,240 Speaker 1: program ever written, and you would have to have the 572 00:33:23,280 --> 00:33:26,160 Speaker 1: most advanced computer system in the world to run it, 573 00:33:26,400 --> 00:33:29,320 Speaker 1: because you would have to be able to identify target 574 00:33:29,800 --> 00:33:35,640 Speaker 1: and eliminate so many UH missiles in such a relatively 575 00:33:36,160 --> 00:33:40,280 Speaker 1: small time frame that UH it would be it would 576 00:33:40,280 --> 00:33:43,320 Speaker 1: be incredibly difficult, and it would need to work perfectly 577 00:33:43,400 --> 00:33:45,400 Speaker 1: the first time it was used, because if it didn't, 578 00:33:45,440 --> 00:33:47,600 Speaker 1: you know, how do you test that. You can't really 579 00:33:47,640 --> 00:33:51,720 Speaker 1: test it until it's necessary. And his point is that 580 00:33:51,840 --> 00:33:56,000 Speaker 1: no software program ever works perfectly the first time you 581 00:33:56,080 --> 00:33:58,280 Speaker 1: use it. You have to you know, you run a program, 582 00:33:58,600 --> 00:34:00,280 Speaker 1: you see where it works, where it doesn't work. You 583 00:34:00,320 --> 00:34:03,800 Speaker 1: do quality assurance, You test it, you write down all 584 00:34:03,800 --> 00:34:05,720 Speaker 1: the things that don't work. You go back to the 585 00:34:05,800 --> 00:34:08,760 Speaker 1: drawing board, you start reprogramming it. You run it again, 586 00:34:08,840 --> 00:34:11,120 Speaker 1: see if anything is fixed. Maybe you broke something even 587 00:34:11,160 --> 00:34:14,839 Speaker 1: worse this time. And his point is that you don't 588 00:34:14,840 --> 00:34:18,359 Speaker 1: get that chance with this system. And and if if 589 00:34:18,400 --> 00:34:20,880 Speaker 1: the system is not guaranteed to work perfectly, if it 590 00:34:20,920 --> 00:34:23,359 Speaker 1: has to be this complex, if it requires the most 591 00:34:23,400 --> 00:34:26,640 Speaker 1: advanced computer system in the world, you're talking about costs 592 00:34:27,280 --> 00:34:29,960 Speaker 1: for something not guaranteed to work, and that therefore it 593 00:34:30,080 --> 00:34:33,960 Speaker 1: is not a worthwhile endeavor. You know, you should not 594 00:34:34,080 --> 00:34:36,520 Speaker 1: pour that huge amount of money into something that may 595 00:34:36,520 --> 00:34:39,880 Speaker 1: not ever work, and it may actually escalate things to 596 00:34:39,920 --> 00:34:46,560 Speaker 1: the point where there's a legitimate conflict. It's a it's 597 00:34:46,600 --> 00:34:50,120 Speaker 1: it's funny now it seems much less of a big deal. 598 00:34:50,440 --> 00:34:54,360 Speaker 1: But I remember a lot of stuff going on in 599 00:34:54,360 --> 00:34:58,920 Speaker 1: the news, just constant, constant talk about the Star Wars program, 600 00:34:58,920 --> 00:35:03,600 Speaker 1: and people still mean it now in legislative sessions about 601 00:35:03,800 --> 00:35:06,200 Speaker 1: sort of as a you know, well this didn't work, 602 00:35:06,280 --> 00:35:09,440 Speaker 1: but I think it in the end, or well, I 603 00:35:09,520 --> 00:35:11,880 Speaker 1: doubt you could really say this is the end even 604 00:35:12,200 --> 00:35:13,880 Speaker 1: I mean some of it, some of it did survive, 605 00:35:13,880 --> 00:35:17,440 Speaker 1: and some of it is pretty successful. Um, it's just 606 00:35:17,680 --> 00:35:20,120 Speaker 1: not really in the way that it was originally and 607 00:35:20,440 --> 00:35:24,399 Speaker 1: not as a complete and not as a complete package. Um. 608 00:35:24,440 --> 00:35:27,960 Speaker 1: But you know, if if it serves as a defensive 609 00:35:28,800 --> 00:35:32,799 Speaker 1: deterrent against having other people launch attacks against you, you know, 610 00:35:32,840 --> 00:35:36,839 Speaker 1: it seems like the idea behind that is is valuable. Yeah, 611 00:35:36,880 --> 00:35:40,520 Speaker 1: the the concern now tends to be more toward well, 612 00:35:40,560 --> 00:35:43,480 Speaker 1: first of all, theater operations, so things that are happening 613 00:35:43,520 --> 00:35:46,080 Speaker 1: in the localized areas. You know, it's still worrying about those. 614 00:35:46,480 --> 00:35:48,920 Speaker 1: But also, I mean, we have a whole new world 615 00:35:49,000 --> 00:35:53,239 Speaker 1: now where we're talking about worrying of things like briefcase bombs. Yes, 616 00:35:53,320 --> 00:35:55,319 Speaker 1: where you're talking about you know, you've got these warheads 617 00:35:55,360 --> 00:35:58,160 Speaker 1: that were laying around, some of which were never installed 618 00:35:58,160 --> 00:35:59,960 Speaker 1: in missiles because like I said, they had they had 619 00:36:00,080 --> 00:36:02,359 Speaker 1: more warheads than they had missiles to launch with them. 620 00:36:02,880 --> 00:36:04,960 Speaker 1: And then not all of them are necessarily accounted for. 621 00:36:05,800 --> 00:36:07,560 Speaker 1: And then that so there's a worry that there may 622 00:36:07,600 --> 00:36:10,840 Speaker 1: be warheads out there in the world that could be 623 00:36:11,320 --> 00:36:14,759 Speaker 1: used for terrorist purposes. And uh, and you know that 624 00:36:15,239 --> 00:36:18,279 Speaker 1: no sd I is going to prevent that because we're 625 00:36:18,280 --> 00:36:22,040 Speaker 1: talking about you know, deploying an explosive device, a nuclear 626 00:36:22,120 --> 00:36:26,600 Speaker 1: device without ever launching a missile. Yeah, and an sd 627 00:36:26,640 --> 00:36:31,560 Speaker 1: I isn't going to protect soldiers from I e. D S. 628 00:36:31,719 --> 00:36:35,840 Speaker 1: Improvised explosive devices, you know, things that are much smaller 629 00:36:35,840 --> 00:36:39,759 Speaker 1: in scale, or people who are willing to sacrifice their 630 00:36:39,800 --> 00:36:41,839 Speaker 1: lives for their cause to the point where they will 631 00:36:41,840 --> 00:36:44,560 Speaker 1: walk into a building and blow it up. Um, you 632 00:36:44,560 --> 00:36:47,839 Speaker 1: know you can't. You can't defend against that with something 633 00:36:47,840 --> 00:36:50,640 Speaker 1: like an sd I, and and even sd I at 634 00:36:50,719 --> 00:36:55,360 Speaker 1: it's like like the best case scenario for SDI was 635 00:36:55,440 --> 00:36:58,560 Speaker 1: not all about stopping every single missile. It was about 636 00:36:58,600 --> 00:37:01,840 Speaker 1: stopping most of them, which would mean that no matter 637 00:37:01,920 --> 00:37:04,320 Speaker 1: what I mean, realistically you have to say, no system 638 00:37:04,360 --> 00:37:06,800 Speaker 1: is perfect. You would not be able to stop everything, 639 00:37:07,239 --> 00:37:10,759 Speaker 1: and therefore there would be losses. It was just a 640 00:37:10,840 --> 00:37:14,120 Speaker 1: question of where the loss is going to be mitigated 641 00:37:14,239 --> 00:37:20,400 Speaker 1: enough for the system to be worthwhile. It's it's heavy topic, 642 00:37:21,760 --> 00:37:26,080 Speaker 1: but yeah, I mean, it's definitely an interesting uh program 643 00:37:26,120 --> 00:37:29,880 Speaker 1: that was was put into place, and you can see 644 00:37:29,880 --> 00:37:33,800 Speaker 1: why it was even though ultimately it may have been 645 00:37:34,880 --> 00:37:37,080 Speaker 1: the wrong direction to to move in. I mean, at 646 00:37:37,080 --> 00:37:40,680 Speaker 1: that point, the political pressure and the fear in the 647 00:37:40,760 --> 00:37:42,440 Speaker 1: United States. I mean, I remember as a kid that 648 00:37:42,480 --> 00:37:44,960 Speaker 1: the Soviets were supposed to be the bad guys, you know. 649 00:37:45,040 --> 00:37:47,440 Speaker 1: I mean, even if if no one directly said that. 650 00:37:47,480 --> 00:37:50,800 Speaker 1: I mean, here, here's all I have to say, Wolverines. 651 00:37:52,920 --> 00:37:54,839 Speaker 1: Of course, now people are gonna think that means North 652 00:37:54,920 --> 00:37:58,160 Speaker 1: Korea because the new movie is going to have the 653 00:37:58,200 --> 00:38:01,520 Speaker 1: North Koreans as the bad guy. But yeah, but originally 654 00:38:01,560 --> 00:38:04,480 Speaker 1: there were the Soviets in the original version of that film. 655 00:38:04,800 --> 00:38:06,640 Speaker 1: I'm sure some of you are gonna have to look 656 00:38:06,719 --> 00:38:10,319 Speaker 1: up what that movie is. Yeah, Wolverines. Yeah, that's a 657 00:38:10,400 --> 00:38:13,360 Speaker 1: nice hard one because it's one word, except for the 658 00:38:13,360 --> 00:38:16,359 Speaker 1: fact that's also a very famous one. So yeah. I mean, 659 00:38:16,400 --> 00:38:19,319 Speaker 1: there was a very real concern both in UH, in 660 00:38:19,760 --> 00:38:22,560 Speaker 1: the news and in pop culture that the Soviets were 661 00:38:22,719 --> 00:38:26,720 Speaker 1: up to UH dangerous activities, and it was our duty 662 00:38:26,760 --> 00:38:30,600 Speaker 1: as Americans to make sure we supported every option we 663 00:38:30,680 --> 00:38:34,040 Speaker 1: had to try and head that off. And um, yeah, 664 00:38:34,120 --> 00:38:39,080 Speaker 1: the whole patriotism directed towards supporting military militarism.
