The most enduring lesson of the Cuban missile crisis is that, in a world with nuclear weapons, a classic military victory is an illusion. Communism was not defeated militarily; it was defeated economically, culturally, and ideologically. Khrushchev’s successors were unable to provide their own people with a basic level of material prosperity and spiritual fulfillment. They lost the war of ideas. In the end, as I have argued in Down with Big Brother: The Fall of the Soviet Empire, communism defeated itself.
