"Nuclear weapons began to exert an important influence on military policy immediately following World War II, although their capabilities, limitations, and political implications were only vaguely understood. But it seemed clear they they represented destructiveness at a cheap price. This point was important because of the need to replace the armed forces demobilized so thoroughly and wastefully at the end of World War II in the furor to "bring the boys home." To have rebuilt similar forces in the succeeding years would have been costly both in dollars and in political "face." Neither the Truman administration nor the American people were prepared to foot such a bill, particularly that part of the program which would have been a tacit admission of lack of foresight. Under such circumstances, it is not surprising that the idea of relying on nuclear weapons and strategic bombing for national defense had great appeal. Such a military program appeared to offer us a way out of fighting dirty, costly wars with Communist masses on the ground. It was a way to meet manpower with mechanical power. Its apparent cheapness gave rise to the slogan, "More bang for a buck." But this reliance on Massive Retaliation overlooked the fact that atomic bangs could eventually be bought for rubles as well as dollars."
