There are too many risks – human error, technical flaws, negligence, cyber attacks, and more – to believe that these weapons will never be used. Nor is there good reason to believe that adequate fail-safe mechanisms are in place.
人为错误、技术缺陷、粗心大意、网络攻击等等等等，核武器有太多的风险无法排除。相信这些武器永远不会被使用是一种错误。而且也没有理由认为建立了充分的故障安全机制。1945年后的核武器史——无论在古巴导弹危机之前还是之后—— 随处可见侥幸逃脱的例子。
