So long as nuclear weapons remain, states can justify maintaining a minimum nuclear-deterrent capability. But that can be done without weapons on high alert, and with drastically reduced arsenals in the case of the US and Russia, and, at worst, at current levels for the other nuclear-armed states.
其次是冷战时期的核威慑论已经无关乎当今世界。只要核武器依然存在，各国就可以名正言顺地保留最基本的核威慑力。但做到这点不需要让核武器处在高度戒备状态，美俄两国需要大幅降低核武器库存，而其他有核国家充其量可以保持目前的核武器状况。
