  • And what happened was -- when we get in to chapter two of the nuclear threat era, which started back in 1945.
  • 而现实是当我们进入1945年开始的核威胁时期的第二阶段
  • Chapter two starts in 1991.
  • 第二个阶段是从1991年开始的
  • When the Soviet Union broke up,
  • 当苏联解体之后
  • we effectively lost that adversary as a potential attacker of the United States, for the most part.
  • 美国实际上上失去了竞争对手,这个长久以来潜在的袭击者基本不复存在了
  • It's not completely gone. I'm going to come back to that.
  • 但苏联的威胁也不是完全消失了,我一会儿会再提到这一点
  • But from 1991 through the present time, emphasized by the attacks of 2001,
  • 从1991年开始直到现在,尤其是2001年的9.11事件说明
  • the idea of an all-out nuclear war has diminished and the idea of a single event,
  • 全面爆发的核战争的可能性已经逐渐减小,
  • act of nuclear terrorism is what we have instead.
  • 取而代之的是单独的核恐怖袭击活动
  • Although the scenario has changed very considerably,
  • 情况虽然和以前大不一样
  • the fact is that we haven't changed our mental image of what a nuclear war means.
  • 但事实是我们头脑里对于核战争的理解并未改变
  • So I'm going to tell you what the implications of that are in just a second.
  • 我一会儿会说明这意味着什么
  • So, what is a nuclear terror threat?
  • 那么,什么是核恐怖袭击呢?
  • And there's four key ingredients to describing that.
  • 它有四个关键组成部分
  • First thing is that the global nuclear weapons,
  • 第一个是全球范围内核武器
  • in the stockpiles that I showed you in those original maps, happen to be not uniformly secure.
  • 就是我之前给大家看的那张地图所显示的核武器储备,其实并不是全部都处于安全状态
  • And it's particularly not secure in the former Soviet Union, now in Russia.
  • 尤其是那些前苏联所拥有的核武器,现在这些核武器在俄罗斯手中
  • There are many, many sites where warheads are stored
  • 这些核弹头储存在很多地方
  • and, in fact, lots of sites where fissionable materials,
  • 可事实上,这其中又很多地方对于储存,
  • like highly enriched uranium and plutonium, are absolutely not safe.
  • 如高浓缩铀和钚这样的裂变物质而言,并不安全
  • They're available to be bought, stolen, whatever.
  • 这些核弹头可能被贩卖或是被偷窃
  • They're acquirable, let me put it that way.
  • 换句话说,它们可以被其他人得到
  • From 1993 through 2006, the International Atomic Energy Agency documented 175 cases of nuclear theft,
  • 从1993年到2006年,国际原子能机构记录在案的核失窃案件就有175起
  • 18 of which involved highly enriched uranium or plutonium,
  • 其中18起和高浓缩铀和钚有关
  • the key ingredients to make a nuclear weapon.
  • 这些是制造核武器的关键原料
  • The global stockpile of highly enriched uranium is about 1,300, at the low end, to about 2,100 metric tons.
  • 全球的高浓缩铀储备大约为1300吨到2100吨之间
  • More than 100 megatons of this is stored in particularly insecure Russian facilities.
  • 其中至少有100吨储存在非常不安全的俄罗斯的储备设施中
  • How much of that do you think it would take to actually build a 10-kiloton bomb?
  • 大家觉得造一个一万吨级当量的核弹,大约需要多少高浓缩铀呢?
  • Well, you need about 75 pounds of it.
  • 你需要大约75磅高浓缩铀
  • So, what I'd like to show you is what it would take to hold 75 pounds of highly enriched uranium.
  • 所以,我想给大家展示一下,那就是75磅高浓缩铀大约是多少呢?
  • This is not a product placement.
  • 我这可不是在做软广告。
  • It's just -- in fact, if I was Coca Cola, I'd be pretty distressed about this --
  • 这只是...事实上,如果我是可口可乐公司,我一定为此非常郁闷
  • but basically, this is it.
  • 但是基本上,就是这么多
  • This is what you would need to steal or buy out of that 100-metric-ton stockpile
  • 你只要从那100吨没有被安全储存的原料中偷取或者购买这么多就够了
  • that's relatively insecure to create the type of bomb that was used in Hiroshima.
  • 储存设施偷取的高浓缩铀总量,从而制造出一个核弹威力相当于在广岛爆炸的那枚核弹
  • Now you might want to look at plutonium as another fissionable material that you might use in a bomb.
  • 现在你们可能想看看如果是钚,另一种可用于制造核弹的裂变物质
  • That -- you'd need 10 to 13 pounds of plutonium.
  • 你需要10到13磅钚
  • Now, plutonium, 10 to 13 pounds: this.
  • 钚,10到13磅,这是这么多,
  • This is enough plutonium to create a Nagasaki-size atomic weapon.
  • 这些钚足以制造一个威力相当于在长崎爆炸的那枚原子弹
