Abstract
Since the atomic era began in 1945, there have been three waves of moral criticism directed at American nuclear weapons policies. The first wave, which began around 1957 and ended in 1962 with McNamara’s announcement of Flexible Response, focused on Dulles’s policy of Massive Retaliation. The second wave, which began in the early 70’s and ended in 1974 with Schlesinger’s announcement of Countervailing Response, focused on the Assured Destruction policy developed in McNamara’s later reports to Congress. The third wave began in the 80’s with Weinberger’s remarks about “prevailing” in nuclear conflicts and may or may not end with the next MX vote or next strategic arms agreement.
