"Even critics must acknowledge that the security arrangements developed after World War II, largely dependent upon nuclear weapons, were successful in giving us a Europe that has been free for fifty years from the major warfare that twice afflicted the continent in the first half of this century. Under the protection of nuclear deterrence, Europe has pursued a policy of economic and political integration that has put to rest age-old antagonisms and centuries of conflict between countries such as France and Germany. Nuclear deterrence also helped to hold off a Communist Soviet Union until the internal contradictions of that regime brought it down. In summary, "morality" must be judged in part by its effects, and if judged by these results, nuclear deterrence was a highly moral and responsible national security policy."
