1
00:00:00,714 --> 00:00:03,444
Let me ask you all a question.

2
00:00:04,282 --> 00:00:08,146
How much weapons-grade nuclear
material do you think it would take

3
00:00:08,170 --> 00:00:10,929
to level a city the size of San Francisco?

4
00:00:11,554 --> 00:00:13,586
How many of you think
it would be an amount

5
00:00:13,610 --> 00:00:15,994
about the size of this suitcase?

6
00:00:17,685 --> 00:00:20,851
OK. And how about this minibus?

7
00:00:22,327 --> 00:00:23,480
All right.

8
00:00:23,504 --> 00:00:26,198
Well actually, under
the right circumstances,

9
00:00:26,222 --> 00:00:31,673
an amount of highly enriched uranium
about the size of your morning latte

10
00:00:31,697 --> 00:00:34,615
would be enough to kill 100,000 people

11
00:00:34,639 --> 00:00:35,865
instantly.

12
00:00:36,522 --> 00:00:40,028
Hundreds of thousands of others
would become horribly ill,

13
00:00:40,616 --> 00:00:43,641
and parts of the city
would be uninhabitable for years,

14
00:00:43,665 --> 00:00:45,112
if not for decades.

15
00:00:45,993 --> 00:00:48,556
But you can forget that nuclear latte,

16
00:00:48,580 --> 00:00:54,550
because today's nuclear weapons
are hundreds of times more powerful

17
00:00:54,574 --> 00:00:58,246
even than those we dropped
on Hiroshima and Nagasaki.

18
00:00:58,891 --> 00:01:04,210
And even a limited nuclear war
involving, say, tens of nuclear weapons,

19
00:01:04,234 --> 00:01:08,386
could lead to the end
of all life on the planet.

20
00:01:09,609 --> 00:01:12,883
So it's really important that you know

21
00:01:12,907 --> 00:01:17,988
that right now we have
over 15,000 nuclear weapons

22
00:01:18,012 --> 00:01:20,227
in the hands of nine nations.

23
00:01:20,251 --> 00:01:24,880
And if you live in a city
or near a military facility,

24
00:01:24,904 --> 00:01:27,899
one is likely pointed right at you.

25
00:01:28,523 --> 00:01:31,414
In fact, if you live in any
of the rural areas

26
00:01:31,438 --> 00:01:33,920
where nuclear weapons are stored globally,

27
00:01:33,944 --> 00:01:35,567
one is likely pointed at you.

28
00:01:36,188 --> 00:01:40,670
About 1,800 of these weapons
are on high alert,

29
00:01:40,694 --> 00:01:44,384
which means they can be launched
within 15 minutes

30
00:01:44,408 --> 00:01:46,644
of a presidential command.

31
00:01:48,228 --> 00:01:51,795
So I know this is a bummer of an issue,

32
00:01:51,819 --> 00:01:54,632
and maybe you have that --
what was it? -- psychic fatigue

33
00:01:54,656 --> 00:01:56,721
that we heard about a little bit earlier.

34
00:01:56,745 --> 00:01:59,048
So I'm going to switch gears
for just a second,

35
00:01:59,072 --> 00:02:01,458
and I'm going to talk
about my imaginary friend,

36
00:02:01,482 --> 00:02:04,268
who I like to think of as Jasmine,

37
00:02:04,292 --> 00:02:05,638
just for a moment.

38
00:02:05,662 --> 00:02:08,179
Jasmine, at the age of 25,

39
00:02:08,203 --> 00:02:12,558
is part of a generation that is more
politically and socially engaged

40
00:02:12,582 --> 00:02:14,987
than anything we've seen in 50 years.

41
00:02:15,011 --> 00:02:16,950
She and her friends think of themselves

42
00:02:16,974 --> 00:02:20,223
as change agents
and leaders and activists.

43
00:02:20,247 --> 00:02:23,389
I think of them as Generation Possible.

44
00:02:24,317 --> 00:02:27,398
They regularly protest
about the issues they care about,

45
00:02:27,422 --> 00:02:30,830
but nuclear weapons are not one of them,
which makes sense,

46
00:02:30,854 --> 00:02:35,052
because Jasmine was born in 1991,
at the end of the Cold War.

47
00:02:35,076 --> 00:02:38,182
So she didn't grow up hearing a lot
about nuclear weapons.

48
00:02:38,206 --> 00:02:41,789
She never had to duck and cover
under her desk at school.

49
00:02:41,813 --> 00:02:46,104
For Jasmine, a fallout shelter
is an app in the Android store.

50
00:02:46,128 --> 00:02:48,823
Nuclear weapons help win games.

51
00:02:48,847 --> 00:02:51,281
And that is really a shame,

52
00:02:51,305 --> 00:02:54,579
because right now, we need
Generation Possible

53
00:02:54,603 --> 00:02:58,894
to help us make some really important
decisions about nuclear weapons.

54
00:02:59,545 --> 00:03:05,981
For instance, will we further reduce
our nuclear arsenals globally,

55
00:03:06,005 --> 00:03:08,921
or will we spend billions,

56
00:03:08,945 --> 00:03:11,168
maybe a trillion dollars,

57
00:03:11,192 --> 00:03:14,514
to modernize them so they last
throughout the 21st century,

58
00:03:14,538 --> 00:03:17,837
so that by the time Jasmine is my age,
she's talking to her children

59
00:03:17,861 --> 00:03:19,792
and maybe even her grandchildren

60
00:03:19,816 --> 00:03:22,447
about the threat of nuclear holocaust?

61
00:03:23,098 --> 00:03:26,004
And if you're paying any attention
at all to cyberthreats,

62
00:03:26,028 --> 00:03:29,995
or, for instance, if you've read
about the Stuxnet virus

63
00:03:30,019 --> 00:03:33,884
or, for God's sake, if you've ever
had an email account or a Yahoo account

64
00:03:33,908 --> 00:03:35,956
or a phone hacked,

65
00:03:35,980 --> 00:03:40,132
you can imagine the whole new world
of hurt that could be triggered

66
00:03:40,156 --> 00:03:43,321
by modernization in a period
of cyberwarfare.

67
00:03:43,944 --> 00:03:46,161
Now, if you're paying
attention to the money,

68
00:03:46,185 --> 00:03:49,246
a trillion dollars could go a long way

69
00:03:49,270 --> 00:03:52,113
to feeding and educating
and employing people,

70
00:03:52,137 --> 00:03:55,872
all of which could reduce the threat
of nuclear war to begin with.

71
00:03:56,691 --> 00:03:57,845
So --

72
00:03:57,869 --> 00:04:00,891
(Applause)

73
00:04:00,915 --> 00:04:03,368
This is really crucial right now,

74
00:04:03,392 --> 00:04:06,179
because nuclear weapons --
they're vulnerable.

75
00:04:07,274 --> 00:04:08,861
We have solid evidence

76
00:04:08,885 --> 00:04:11,775
that terrorists are trying
to get ahold of them.

77
00:04:12,551 --> 00:04:13,872
Just this last spring,

78
00:04:13,896 --> 00:04:18,602
when four retirees
and two taxi drivers were arrested

79
00:04:18,626 --> 00:04:20,225
in the Republic of Georgia

80
00:04:20,249 --> 00:04:23,974
for trying to sell nuclear materials
for 200 million dollars,

81
00:04:23,998 --> 00:04:27,766
they demonstrated that the black market
for this stuff is alive and well.

82
00:04:28,111 --> 00:04:29,372
And it's really important,

83
00:04:29,396 --> 00:04:33,193
because there have been
dozens of accidents

84
00:04:33,217 --> 00:04:34,498
involving nuclear weapons,

85
00:04:34,522 --> 00:04:37,563
and I bet most of us have never heard
anything about them.

86
00:04:37,587 --> 00:04:39,129
Just here in the United States,

87
00:04:39,153 --> 00:04:42,651
we've dropped nuclear weapons
on the Carolinas twice.

88
00:04:43,203 --> 00:04:45,529
In one case, one of the bombs,

89
00:04:45,553 --> 00:04:47,725
which fell out of an Air Force plane,

90
00:04:47,749 --> 00:04:48,948
didn't detonate

91
00:04:48,972 --> 00:04:52,085
because the nuclear core
was stored somewhere else on the plane.

92
00:04:52,109 --> 00:04:56,145
In another case, the weapon
did arm when it hit the ground,

93
00:04:56,169 --> 00:05:00,340
and five of the switches designed
to keep it from detonating failed.

94
00:05:00,935 --> 00:05:02,602
Luckily, the sixth one didn't.

95
00:05:03,521 --> 00:05:05,838
But if that's not enough
to get your attention,

96
00:05:06,973 --> 00:05:10,060
there was the 1995 Black Brant incident.

97
00:05:10,655 --> 00:05:12,934
That's when Russian radar technicians saw

98
00:05:12,958 --> 00:05:15,477
what they thought was a US nuclear missile

99
00:05:15,501 --> 00:05:18,148
streaking towards Russian airspace.

100
00:05:18,172 --> 00:05:20,892
It later turned out to be
a Norwegian rocket

101
00:05:20,916 --> 00:05:23,498
collecting data about the northern lights.

102
00:05:23,522 --> 00:05:24,676
But at that time,

103
00:05:24,700 --> 00:05:28,471
Russian President Boris Yeltsin
came within five minutes

104
00:05:28,495 --> 00:05:32,647
of launching a full-scale
retaliatory nuclear attack

105
00:05:32,671 --> 00:05:34,503
against the United States.

106
00:05:36,924 --> 00:05:40,966
So, most of the world's nuclear nations

107
00:05:40,990 --> 00:05:44,455
have committed to getting rid
of these weapons of mass destruction.

108
00:05:45,352 --> 00:05:46,828
But consider this:

109
00:05:47,835 --> 00:05:51,159
the Treaty on the Non-Proliferation
of Nuclear Weapons,

110
00:05:51,183 --> 00:05:54,620
which is the most widely adopted
arms control treaty in history

111
00:05:54,644 --> 00:05:56,787
with 190 signatories,

112
00:05:57,398 --> 00:06:02,692
sets no specific date by which
the world's nuclear-armed nations

113
00:06:02,716 --> 00:06:04,923
will get rid of their nuclear weapons.

114
00:06:05,692 --> 00:06:08,462
Now, when John F. Kennedy
sent a man to the moon

115
00:06:08,486 --> 00:06:11,657
and decided to bring him back,
or decided to do both those things,

116
00:06:11,681 --> 00:06:14,601
he didn't say, "Hey, whenever
you guys get to it."

117
00:06:14,625 --> 00:06:16,632
He gave us a deadline.

118
00:06:16,656 --> 00:06:18,478
He gave us a challenge

119
00:06:18,502 --> 00:06:22,009
that would have been incredible
just a few years earlier.

120
00:06:22,033 --> 00:06:23,535
And with that challenge,

121
00:06:23,559 --> 00:06:26,434
he inspired scientists and marketers,

122
00:06:26,458 --> 00:06:29,128
astronauts and schoolteachers.

123
00:06:29,152 --> 00:06:31,185
He gave us a vision.

124
00:06:31,928 --> 00:06:33,903
But along with that vision,

125
00:06:33,927 --> 00:06:37,471
he also tried to give us -- and most
people don't know this, either --

126
00:06:37,495 --> 00:06:39,479
he tried to give us a partner

127
00:06:39,503 --> 00:06:44,924
in the form of our fiercest
Cold War rival, the Soviet Union.

128
00:06:44,948 --> 00:06:47,982
Because part of Kennedy's vision
for the Apollo program

129
00:06:48,006 --> 00:06:51,793
was that it be a cooperation,
not a competition, with the Soviets.

130
00:06:51,817 --> 00:06:55,370
And apparently, Nikita Khrushchev,
the Soviet Premier, agreed.

131
00:06:56,007 --> 00:06:59,323
But before that cooperation
could be realized,

132
00:06:59,347 --> 00:07:01,018
Kennedy was assassinated,

133
00:07:01,042 --> 00:07:03,391
and that part of the vision was deferred.

134
00:07:04,581 --> 00:07:09,760
But the promise of joint innovation
between these two nuclear superpowers

135
00:07:09,784 --> 00:07:11,656
wasn't totally extinguished.

136
00:07:12,305 --> 00:07:16,198
Because in 1991, which is the year
that Jasmine was born

137
00:07:16,222 --> 00:07:18,708
and the Soviet Union fell,

138
00:07:18,732 --> 00:07:21,505
these two nations engaged in a project

139
00:07:21,529 --> 00:07:24,086
that genuinely does seem incredible today

140
00:07:24,110 --> 00:07:26,156
in the truest sense of that word,

141
00:07:26,812 --> 00:07:31,408
which is that the US sent cash
to the Russians when they needed it most,

142
00:07:31,432 --> 00:07:34,187
to secure loose nuclear materials

143
00:07:34,211 --> 00:07:37,416
and to employ out-of-work
nuclear scientists.

144
00:07:37,440 --> 00:07:44,143
They worked alongside American scientists
to convert weapons-grade uranium

145
00:07:44,167 --> 00:07:48,046
into the type of fuel that can be used
for nuclear power instead.

146
00:07:48,464 --> 00:07:51,473
They called it, "Megatons to Megawatts."

147
00:07:52,202 --> 00:07:55,338
So the result is that for over 20 years,

148
00:07:55,362 --> 00:07:58,169
our two nations had a program

149
00:07:58,193 --> 00:08:02,006
that meant that one in 10 lightbulbs
in the United States

150
00:08:02,030 --> 00:08:06,236
was essentially fueled
by former Russian warheads.

151
00:08:07,530 --> 00:08:11,301
So, together these two nations
did something truly audacious.

152
00:08:11,905 --> 00:08:15,974
But the good news is,
the global community has the chance

153
00:08:15,998 --> 00:08:19,000
to do something just as audacious today.

154
00:08:20,897 --> 00:08:23,424
To get rid of nuclear weapons

155
00:08:23,448 --> 00:08:27,986
and to end the supply of the materials
required to produce them,

156
00:08:28,010 --> 00:08:30,702
some experts tell me would take 30 years.

157
00:08:31,219 --> 00:08:33,686
It would take a renaissance of sorts,

158
00:08:33,710 --> 00:08:36,125
the kinds of innovation that,
for better or worse,

159
00:08:36,149 --> 00:08:40,123
underpinned both the Manhattan Project,
which gave rise to nuclear weapons,

160
00:08:40,147 --> 00:08:42,559
and the Megatons to Megawatts program.

161
00:08:43,019 --> 00:08:45,641
It would take design constraints.

162
00:08:45,665 --> 00:08:48,383
These are fundamental to creativity,

163
00:08:48,407 --> 00:08:52,423
things like a platform
for international collaboration;

164
00:08:52,447 --> 00:08:56,139
a date certain, which is
a forcing mechanism;

165
00:08:56,925 --> 00:09:00,174
and a positive vision
that inspires action.

166
00:09:00,735 --> 00:09:03,198
It would take us to 2045.

167
00:09:04,468 --> 00:09:08,949
Now, 2045 happens to be
the 100th anniversary

168
00:09:08,973 --> 00:09:12,247
of the birth of nuclear weapons
in the New Mexico desert.

169
00:09:13,247 --> 00:09:15,971
But it's also an important date
for another reason.

170
00:09:16,458 --> 00:09:20,321
It's predicted to be the advent
of the singularity,

171
00:09:21,011 --> 00:09:23,407
a new moment in human development,

172
00:09:23,431 --> 00:09:28,551
where the lines between artificial
intelligence and human intelligence blur,

173
00:09:29,106 --> 00:09:33,535
where computing and consciousness
become almost indistinguishable

174
00:09:33,559 --> 00:09:39,191
and advanced technologies help us solve
the 21st century's greatest problems:

175
00:09:39,215 --> 00:09:41,547
hunger, energy, poverty,

176
00:09:42,133 --> 00:09:45,418
ushering in an era of abundance.

177
00:09:46,318 --> 00:09:47,900
And we all get to go to space

178
00:09:47,924 --> 00:09:50,783
on our way to becoming
a multi-planetary species.

179
00:09:52,039 --> 00:09:55,891
Now, the people who really believe
this vision are the first to say

180
00:09:55,915 --> 00:09:58,938
they don't yet know precisely
how we're going to get there.

181
00:09:59,618 --> 00:10:02,410
But the values behind their vision

182
00:10:02,434 --> 00:10:05,765
and the willingness to ask "How might we?"

183
00:10:05,789 --> 00:10:08,290
have inspired a generation of innovators.

184
00:10:08,884 --> 00:10:12,356
They're working backward
from the outcomes they want,

185
00:10:12,380 --> 00:10:16,584
using the creative problem-solving methods
of collaborative design.

186
00:10:16,608 --> 00:10:18,848
They're busting through obstacles.

187
00:10:18,872 --> 00:10:22,586
They're redefining
what we all consider possible.

188
00:10:23,513 --> 00:10:24,721
But here's the thing:

189
00:10:25,706 --> 00:10:29,916
that vision of abundance isn't compatible

190
00:10:29,940 --> 00:10:36,145
with a world that still relies
on a 20th-century nuclear doctrine

191
00:10:36,169 --> 00:10:39,730
called "mutually assured destruction."

192
00:10:40,945 --> 00:10:46,422
It has to be about building
the foundations for the 22nd century.

193
00:10:46,446 --> 00:10:52,252
It has to be about strategies
for mutually assured prosperity

194
00:10:52,276 --> 00:10:56,256
or, at the very least,
mutually assured survival.

195
00:10:57,175 --> 00:11:02,398
Now, every day, I get to meet
people who are real pioneers

196
00:11:02,422 --> 00:11:04,339
in the field of nuclear threats.

197
00:11:04,363 --> 00:11:07,864
As you can see, many of them
are young women,

198
00:11:07,888 --> 00:11:10,464
and they're doing fiercely
interesting stuff,

199
00:11:10,488 --> 00:11:14,991
like Mareena Robinson Snowden here,
who is developing new ways,

200
00:11:15,015 --> 00:11:17,677
better ways, to detect nuclear warheads,

201
00:11:17,701 --> 00:11:19,924
which will help us
overcome a critical hurdle

202
00:11:19,948 --> 00:11:21,882
to international disarmament.

203
00:11:21,906 --> 00:11:24,775
Or Melissa Hanham, who is using
satellite imaging

204
00:11:24,799 --> 00:11:28,904
to make sense of what's going on
around far-flung nuclear sites.

205
00:11:29,358 --> 00:11:32,055
Or we have Beatrice Fihn in Europe,

206
00:11:32,079 --> 00:11:36,352
who has been campaigning
to make nuclear weapons illegal

207
00:11:36,376 --> 00:11:38,060
in international courts of law,

208
00:11:38,084 --> 00:11:40,976
and just won a big victory
at the UN last week.

209
00:11:41,000 --> 00:11:44,178
(Applause)

210
00:11:44,202 --> 00:11:45,416
And yet,

211
00:11:45,942 --> 00:11:47,131
and yet,

212
00:11:47,797 --> 00:11:51,215
with all of our talk in this culture
about moon shots,

213
00:11:51,239 --> 00:11:55,967
too few members of Generation Possible
and those of us who mentor them

214
00:11:55,991 --> 00:11:57,957
are taking on nuclear weapons.

215
00:11:58,524 --> 00:12:00,461
It's as if there's a taboo.

216
00:12:01,898 --> 00:12:06,573
But I remember something Kennedy said
that has really stuck with me,

217
00:12:06,597 --> 00:12:08,355
and that is something to the effect

218
00:12:08,379 --> 00:12:10,521
that humans can be as big as the solutions

219
00:12:10,545 --> 00:12:12,403
to all the problems we've created.

220
00:12:12,427 --> 00:12:15,661
No problem of human destiny, he said,

221
00:12:15,685 --> 00:12:18,330
is beyond human beings.

222
00:12:19,296 --> 00:12:20,679
I believe that.

223
00:12:21,376 --> 00:12:23,644
And I bet a lot of you here
believe that, too.

224
00:12:24,535 --> 00:12:27,162
And I know Generation
Possible believes it.

225
00:12:28,646 --> 00:12:31,865
So it's time to commit to a date.

226
00:12:33,183 --> 00:12:36,711
Let's end the nuclear weapons chapter

227
00:12:36,735 --> 00:12:39,920
on the 100th anniversary of its inception.

228
00:12:41,119 --> 00:12:45,845
After all, by 2045, we will have held
billions of people hostage

229
00:12:45,869 --> 00:12:48,143
to the threat of nuclear annihilation.

230
00:12:48,167 --> 00:12:50,433
Surely, 100 years will have been enough.

231
00:12:51,512 --> 00:12:55,191
Surely, a century of economic development

232
00:12:55,215 --> 00:12:58,610
and the development of military strategy

233
00:12:58,634 --> 00:13:02,298
will have given us better ways
to manage global conflict.

234
00:13:02,802 --> 00:13:06,933
Surely, if ever there was a global
moon shot worth supporting,

235
00:13:07,759 --> 00:13:08,941
this is it.

236
00:13:09,846 --> 00:13:12,460
Now, in the face of real threats --

237
00:13:12,484 --> 00:13:15,480
for instance, North Korea's recent
nuclear weapons tests,

238
00:13:15,504 --> 00:13:17,784
which fly in the face of sanctions --

239
00:13:17,808 --> 00:13:20,108
reasonable people disagree

240
00:13:20,132 --> 00:13:24,031
about whether we should maintain
some number of nuclear weapons

241
00:13:24,055 --> 00:13:25,582
to deter aggression.

242
00:13:26,550 --> 00:13:29,454
But the question is:
What's the magic number?

243
00:13:30,205 --> 00:13:31,601
Is it a thousand?

244
00:13:32,140 --> 00:13:34,621
Is it a hundred? Ten?

245
00:13:35,246 --> 00:13:36,673
And then we have to ask:

246
00:13:37,395 --> 00:13:39,352
Who should be responsible for them?

247
00:13:40,038 --> 00:13:41,896
I think we can agree, however,

248
00:13:41,920 --> 00:13:45,969
that having 15,000 of them
represents a greater global threat

249
00:13:45,993 --> 00:13:48,374
to Jasmine's generation than a promise.

250
00:13:49,184 --> 00:13:52,342
So it's time we make a promise

251
00:13:52,366 --> 00:13:55,079
of a world in which we've broken
the stranglehold

252
00:13:55,103 --> 00:13:58,601
that nuclear weapons have
on our imaginations;

253
00:13:58,625 --> 00:14:01,237
in which we invest
in the creative solutions

254
00:14:01,261 --> 00:14:04,991
that come from working backward
from the future we desperately want,

255
00:14:05,015 --> 00:14:07,549
rather than plodding forward
from a present

256
00:14:07,573 --> 00:14:11,933
that brings all of the mental models
and biases of the past with it.

257
00:14:12,392 --> 00:14:17,694
It's time we pledge our resources
as leaders across the spectrum

258
00:14:17,718 --> 00:14:20,607
to work on this old problem in new ways,

259
00:14:21,146 --> 00:14:23,231
to ask, "How might we?"

260
00:14:24,001 --> 00:14:26,304
How might we make good on a promise

261
00:14:26,328 --> 00:14:29,905
of greater security
for Jasmine's generation

262
00:14:29,929 --> 00:14:32,894
in a world beyond nuclear weapons?

263
00:14:34,116 --> 00:14:36,869
I truly hope you will join us.

264
00:14:37,782 --> 00:14:38,945
Thank you.

265
00:14:38,969 --> 00:14:42,271
(Applause)

266
00:14:42,295 --> 00:14:43,968
Thank you.

267
00:14:43,992 --> 00:14:46,142
(Applause)
