"What kept war from breaking out, in the fall of 1962, was the irrationality, on both sides, of sheer terror. That is what Churchill had foreseen when he saw hope in an "equality of annihilation." It is what Eisenhower had understood when he ruled out fighting limited nuclear wars: his strategy left no option than an assurance of total destruction, on the assumption that this, rather than trying to orchestrate levels of destruction while a war was going on, would best prevent any war at all from breaking out."
