Since the closing days of the World War II, we have witnessed an evolution of the national nuclear deterrence strategy. From the early days of Massive Retaliation, born of our nuclear monopoly, we have seen the strategy pass through stages of Mutual Assured Destruction, Flexible Response, and a graduated scale of destruction sufficiency. But today’s radically altered geopolitical environment calls for a radically altered deterrent strategy.
