0:00:01.496,0:00:04.391 So you know when[br]you're doubled over in pain 0:00:04.415,0:00:06.613 and you're wondering, is it your appendix 0:00:06.637,0:00:08.353 or maybe you ate something funny? 0:00:09.472,0:00:13.185 Well, when that happens to me,[br]I call my friend Sasha -- 0:00:13.209,0:00:14.376 Sasha is a doctor -- 0:00:14.400,0:00:17.096 and I say, "Should I rush[br]to the nearest emergency room 0:00:17.120,0:00:18.491 in a panic? 0:00:18.515,0:00:21.813 Or am I OK to relax and just wait it out?" 0:00:21.837,0:00:24.900 Yes, I am that annoying friend. 0:00:27.011,0:00:29.416 But in September 2017, 0:00:29.440,0:00:32.726 friends of mine were suddenly calling me 0:00:32.750,0:00:34.305 for my professional opinion. 0:00:35.868,0:00:37.630 And no, I'm not a doctor, 0:00:37.654,0:00:40.209 but they were asking me[br]questions of life and death. 0:00:41.444,0:00:44.519 So what was going on in September of 2017? 0:00:45.370,0:00:49.806 Well, North Korea was suddenly[br]and scarily all over the news. 0:00:50.752,0:00:52.997 Kim Jong-un had tested missiles 0:00:53.021,0:00:56.943 potentially capable of hitting[br]major US cities, 0:00:56.967,0:01:00.862 and President Trump had responded[br]with tweets of "fire and fury." 0:01:02.097,0:01:06.161 And there was real concern[br]that tensions would escalate 0:01:06.185,0:01:07.661 to a potential war 0:01:07.685,0:01:09.993 or even nuclear weapons use. 0:01:11.067,0:01:13.821 So what my friends[br]were calling and asking was: 0:01:13.845,0:01:17.297 Should they panic or were the OK to relax? 0:01:18.615,0:01:22.813 But really, they were asking me[br]a fundamental question: 0:01:24.440,0:01:26.059 "Am I safe?" 0:01:28.396,0:01:32.872 While I was reassuring them that,[br]no, they didn't need to worry just yet, 0:01:32.896,0:01:35.015 the irony of their question dawned on me. 0:01:36.094,0:01:39.043 What they hadn't really thought about 0:01:39.067,0:01:42.814 is that we've all been living[br]under a much larger cloud for decades -- 0:01:42.838,0:01:44.964 potentially a mushroom cloud -- 0:01:44.988,0:01:46.748 without giving it much thought. 0:01:48.114,0:01:50.194 Now it's not surprising[br]that friends of mine 0:01:50.218,0:01:53.249 and many others like them[br]don't know much about nuclear weapons 0:01:53.273,0:01:54.813 and don't think about them. 0:01:54.837,0:01:57.756 After all, the end of the Cold War, 0:01:57.780,0:02:01.611 the United States and Russia,[br]tension abated, 0:02:01.635,0:02:03.507 we started dismantling nuclear weapons, 0:02:03.531,0:02:06.554 and they started to become[br]a relic of the past. 0:02:07.177,0:02:10.329 Generations didn't have to grow up[br]with the specter of nuclear war 0:02:10.353,0:02:11.558 hanging over their heads. 0:02:13.367,0:02:16.884 And there other reasons people don't like[br]to think about nuclear weapons. 0:02:16.908,0:02:19.358 It's scary, overwhelming. 0:02:19.382,0:02:20.725 I get it. 0:02:20.749,0:02:23.916 Sometimes I wish I could have chosen[br]a cheerier field to study. 0:02:23.940,0:02:24.986 (Laughter) 0:02:25.010,0:02:27.240 Perhaps tax law would[br]have been more uplifting. 0:02:27.264,0:02:28.755 (Laughter) 0:02:30.557,0:02:32.812 But in addition to that, 0:02:32.836,0:02:36.224 people have so many other things[br]to think about in their busy lives, 0:02:36.248,0:02:39.034 and they'd much prefer to think[br]about something over which 0:02:39.058,0:02:41.710 they feel they have[br]some semblance of control, 0:02:41.734,0:02:45.273 and they assume that other people,[br]smarter than they on this topic, 0:02:45.297,0:02:47.726 are working away to keep us all safe. 0:02:49.317,0:02:52.658 And then, there are other reasons[br]people don't talk about this, 0:02:52.682,0:02:55.468 and one is because we, as nuclear experts, 0:02:55.492,0:02:58.863 use a whole lot of convoluted[br]jargon and terminology 0:02:58.887,0:03:00.482 to talk about these issues: 0:03:01.227,0:03:04.834 CVID, ICBM, JCPOA. 0:03:05.782,0:03:08.909 It's really inaccessible[br]for a lot of people. 0:03:09.678,0:03:13.312 And, in reality, it actually sometimes[br]I think makes us numb 0:03:13.336,0:03:15.614 to what we're really talking about here. 0:03:16.843,0:03:19.494 And what we are really talking about here 0:03:19.518,0:03:20.669 is the fact that, 0:03:20.693,0:03:23.933 while we've made dramatic reductions[br]in the number of nuclear weapons 0:03:23.957,0:03:25.344 since the Cold War, 0:03:25.368,0:03:30.693 right now, there are almost 15,000[br]in the world today. 0:03:31.806,0:03:33.463 15,000. 0:03:35.709,0:03:40.403 The United States and Russia have[br]over 90 percent of these nuclear weapons. 0:03:41.034,0:03:44.422 If you're wondering, these are[br]the countries that have the rest. 0:03:45.303,0:03:47.074 But they have far fewer, 0:03:47.098,0:03:50.272 ranging in the sort of[br]300-ish range and below. 0:03:53.112,0:03:56.678 Adding to this situation is the fact[br]that we have new technologies 0:03:56.702,0:03:59.154 that potentially bring us new challenges. 0:03:59.791,0:04:05.250 Could you imagine, one day,[br]countries like ours and others 0:04:05.274,0:04:09.932 potentially ceding decisions[br]about a nuclear strike to a robot, 0:04:10.688,0:04:12.789 based on algorithms? 0:04:12.813,0:04:15.432 And what data do they use[br]to inform those algorithms? 0:04:16.438,0:04:18.145 This is pretty terrifying. 0:04:19.098,0:04:23.820 So adding to this are terrorism potential, 0:04:23.844,0:04:26.710 cyberattacks, miscalculation,[br]misunderstanding. 0:04:26.734,0:04:30.249 The list of nuclear nightmares[br]tends to grow longer by the day. 0:04:30.273,0:04:33.011 And there are a number[br]of former officials, 0:04:33.035,0:04:34.774 as well as experts, 0:04:34.798,0:04:38.051 who worry that right now,[br]we're in greater danger 0:04:38.075,0:04:41.304 than we were in various points[br]in the Cold War. 0:04:42.759,0:04:44.197 So this is scary. 0:04:44.877,0:04:46.179 What can we do? 0:04:46.958,0:04:48.108 Well, thankfully, 0:04:48.132,0:04:49.298 ["Duck and Cover"] 0:04:49.322,0:04:52.695 we don't have to rely[br]on the advice from the 1950s. 0:04:52.719,0:04:53.727 (Laughter) 0:04:53.751,0:04:55.736 We can take some control, 0:04:55.760,0:04:57.504 and the way we do that 0:04:57.528,0:05:00.759 is by starting to ask[br]some fundamental questions 0:05:00.783,0:05:02.787 about the status quo 0:05:02.811,0:05:05.535 and whether we are happy[br]with the way it is. 0:05:06.529,0:05:08.735 We need to begin asking[br]questions of ourselves 0:05:08.759,0:05:10.503 and of our elected officials, 0:05:10.527,0:05:12.790 and I'd like to share[br]three with you today. 0:05:14.798,0:05:16.996 The first one is, 0:05:17.020,0:05:21.099 "How much nuclear risk[br]are you willing to take or tolerate?" 0:05:22.805,0:05:26.701 Right now, nuclear policy[br]depends on deterrence theory. 0:05:27.336,0:05:29.058 Developed in the 1950s, 0:05:29.082,0:05:31.750 the idea is that one[br]country's nuclear weapons 0:05:31.774,0:05:34.761 prevents another country[br]from using theirs. 0:05:34.785,0:05:38.511 So you nuke me, I nuke you, 0:05:38.535,0:05:39.828 and we both lose. 0:05:40.794,0:05:43.474 So in a way, there's a stalemate. 0:05:43.498,0:05:46.028 No one uses their weapons,[br]and we're all safe. 0:05:47.487,0:05:52.686 But this theory has real questions. 0:05:52.710,0:05:55.511 There are experts[br]who challenge this theory 0:05:55.535,0:05:58.662 and wonder: Does it really work[br]this way in practice? 0:05:59.516,0:06:04.492 It certainly doesn't allow[br]for mistakes or miscalculations. 0:06:05.918,0:06:07.968 Now, I don't know about you, 0:06:07.992,0:06:13.110 but I feel pretty uncomfortable[br]gambling my future survival, 0:06:13.134,0:06:16.659 yours, and our future generations', 0:06:16.683,0:06:19.302 on a theory that is questionable 0:06:20.275,0:06:22.706 and doesn't allow any room for a mistake. 0:06:24.560,0:06:26.506 It makes me even more uncomfortable 0:06:27.386,0:06:30.244 to be threatening the evaporation 0:06:30.268,0:06:32.799 of millions of people[br]on the other side of the Earth. 0:06:34.267,0:06:37.379 Surely we can do better for ourselves, 0:06:37.403,0:06:40.967 drawing on our ingenuity[br]to solve complex problems, 0:06:40.991,0:06:43.008 as we have in the past. 0:06:43.032,0:06:45.705 After all, this is a man-made, 0:06:45.729,0:06:46.950 human-made -- 0:06:46.974,0:06:49.497 I shouldn't say "man,"[br]because women were involved -- 0:06:49.521,0:06:51.157 a human-made problem. 0:06:52.669,0:06:55.657 We have human solutions[br]that should be possible. 0:06:57.238,0:07:01.038 So, next question: "Who do you think[br]should make nuclear decisions?" 0:07:02.221,0:07:06.834 Right now, in this democracy,[br]in the United States, 0:07:06.858,0:07:08.635 one person 0:07:09.588,0:07:13.040 gets to decide whether or not[br]to launch a nuclear strike. 0:07:14.691,0:07:16.596 They don't have to consult anybody. 0:07:18.108,0:07:19.984 So that's the president. 0:07:20.742,0:07:23.639 He or she can decide -- 0:07:23.663,0:07:25.798 within a very limited amount of time, 0:07:25.822,0:07:29.155 under great pressure, potentially,[br]depending on the scenario, 0:07:30.204,0:07:33.649 maybe based on a miscalculation[br]or a misunderstanding -- 0:07:34.197,0:07:37.046 they can decide the fate[br]of millions of lives: 0:07:37.805,0:07:40.475 yours, mine, our community's. 0:07:42.173,0:07:46.303 And they can do this[br]and launch a nuclear strike, 0:07:46.327,0:07:50.908 potentially setting in motion[br]the annihilation of the human race. 0:07:53.566,0:07:54.716 Wow. 0:07:56.392,0:07:59.494 This doesn't have to be[br]our reality, though, and in fact, 0:07:59.518,0:08:02.838 in a number of other countries[br]that have nuclear weapons, it's not, 0:08:02.862,0:08:05.582 including countries[br]that are not democracies. 0:08:07.595,0:08:09.841 We created this system. We can change it. 0:08:10.690,0:08:13.546 And there's actually a movement[br]underway to do so. 0:08:13.991,0:08:16.810 So this leads me to my third question: 0:08:16.834,0:08:20.602 "What do your elected officials[br]know about nuclear weapons, 0:08:20.626,0:08:24.119 and what types of decisions[br]are they likely to take on your behalf?" 0:08:25.416,0:08:28.606 Well, Congress has[br]a very important role to play 0:08:28.630,0:08:32.900 in oversight of and interrogating[br]US nuclear weapons policy. 0:08:33.397,0:08:35.993 They can decide what to fund,[br]what not to fund, 0:08:36.017,0:08:37.388 and they represent you. 0:08:38.515,0:08:41.524 Now unfortunately,[br]since the end of the Cold War, 0:08:41.548,0:08:45.037 we've seen a real decline[br]in the level of understanding, 0:08:45.061,0:08:47.687 on Capitol Hill, about these issues. 0:08:47.711,0:08:51.759 While we are starting to see[br]some terrific new champions emerge, 0:08:51.783,0:08:54.632 the reality is that the general[br]lack of awareness 0:08:54.656,0:08:56.228 is highly concerning, 0:08:56.252,0:09:00.124 given that these people need to make[br]critically important decisions. 0:09:02.076,0:09:03.227 To make matters worse, 0:09:03.251,0:09:06.979 the political partisanship[br]that currently grips Washington 0:09:07.003,0:09:08.591 also affects this issue. 0:09:09.814,0:09:11.577 This wasn't always the case, though. 0:09:11.601,0:09:14.846 At the end of the Cold War,[br]members from both sides of the aisle 0:09:14.870,0:09:18.997 had a really good understanding about[br]the nuclear challenges we were facing 0:09:19.021,0:09:22.053 and worked together[br]on cooperative programs. 0:09:22.847,0:09:25.982 They recognized[br]that nuclear risk reduction 0:09:26.006,0:09:30.196 was far too important to allow it[br]to succumb to political partisanship. 0:09:31.350,0:09:32.548 They created programs 0:09:32.572,0:09:35.895 such as the Nunn-Lugar Cooperative[br]Threat Reduction Program, 0:09:35.919,0:09:38.438 which sought to lock down and eliminate 0:09:38.462,0:09:41.445 vulnerable nuclear material[br]in the former Soviet Union. 0:09:42.828,0:09:46.788 So we need to return to this era[br]of bipartisanship, 0:09:46.812,0:09:49.462 mutual problem-solving 0:09:49.486,0:09:53.407 that's based on understanding[br]and awareness about the challenges we face 0:09:53.431,0:09:55.399 and the real nuclear dangers. 0:09:56.273,0:09:58.103 And that's where you come in. 0:09:58.469,0:10:00.311 Public pressure is important. 0:10:01.018,0:10:04.270 Leaders need a constituent base to act. 0:10:04.294,0:10:06.724 So create that constituent base, 0:10:06.748,0:10:09.713 by asking them some simple questions. 0:10:10.325,0:10:13.831 Ask them, "What do you know[br]about nuclear weapons?" 0:10:13.855,0:10:16.498 "Do you have a nuclear expert[br]on your staff? 0:10:16.522,0:10:19.759 Or, if not, do you know[br]somebody you could refer to 0:10:19.783,0:10:21.989 if you need to make[br]an important decision?" 0:10:22.713,0:10:24.972 Start to find out what they believe 0:10:24.996,0:10:27.798 and whether it aligns[br]with your own views and values. 0:10:28.450,0:10:32.637 Ask them, "How would you choose[br]to spend US national treasure? 0:10:34.266,0:10:36.369 On a new nuclear arms race 0:10:36.393,0:10:38.601 or another national security priority, 0:10:38.625,0:10:42.008 such as cybersecurity or climate change?" 0:10:42.032,0:10:45.959 Ask them, "Are you willing[br]to put aside partisanship 0:10:45.983,0:10:50.904 to address this existential threat[br]that affects my survival 0:10:50.928,0:10:52.643 and your constituents' survival?" 0:10:54.305,0:10:58.940 Now, people will tell you nuclear policy[br]is far too difficult to understand 0:10:58.964,0:11:02.844 and complexed and nuanced[br]for the general public to understand, 0:11:02.868,0:11:04.463 let alone debate. 0:11:04.487,0:11:07.083 After all, this is "national security." 0:11:07.900,0:11:09.391 There needs to be secrets. 0:11:10.677,0:11:12.581 Don't let that put you off. 0:11:12.605,0:11:14.416 We debate all sorts of issues 0:11:14.440,0:11:16.701 that are critically important[br]to our lives -- 0:11:16.725,0:11:19.113 why should nuclear weapons[br]be any different? 0:11:19.137,0:11:22.153 We debate health care,[br]education, the environment. 0:11:22.177,0:11:25.195 Surely congressional oversight, 0:11:25.605,0:11:29.615 civic participation that are[br]such hallmarks of US democracy, 0:11:29.639,0:11:31.590 surely they apply here. 0:11:32.573,0:11:36.922 After all, these are cases of life[br]and death that we're talking about. 0:11:38.021,0:11:40.295 And we won't all agree, 0:11:40.319,0:11:43.993 but whether or not you believe[br]nuclear weapons keep us safe 0:11:44.017,0:11:47.207 or that nuclear weapons are a liability, 0:11:47.231,0:11:52.715 I urge you to put aside[br]partisan, ideological issues 0:11:52.739,0:11:54.695 and listen to each other. 0:11:56.254,0:12:00.643 So I'll tell you now what I didn't have[br]the guts to tell my friends at the time. 0:12:01.483,0:12:03.737 No, you're not safe -- 0:12:04.273,0:12:05.988 not just because of North Korea. 0:12:06.798,0:12:09.616 But there is something[br]you can do about it. 0:12:11.266,0:12:14.743 Demand that your elected representatives 0:12:14.767,0:12:17.774 can give you answers to your questions, 0:12:17.798,0:12:20.465 and answers that you can live with 0:12:20.489,0:12:23.099 and that billions of others[br]can live with too. 0:12:24.644,0:12:25.925 And if they can't, 0:12:25.949,0:12:28.186 stay on them until they can. 0:12:29.284,0:12:31.042 And if that doesn't work, 0:12:31.066,0:12:35.609 find others, who are able[br]to represent your views. 0:12:36.895,0:12:42.338 Because by doing so, we can begin[br]to change the answer to the question 0:12:42.362,0:12:43.512 "Am I safe?" 0:12:45.111,0:12:49.095 (Applause)
