On August 8, 1945, two days after the bombing, former Republican President Herbert Hoover wrote to a friend that "[t]he use of the atomic bomb, with its indiscriminate killing of women and children, revolts my soul."

Days later, David Lawrence, the conservative owner and editor of U.S. News (now U.S. News & World Report), argued that Japan's surrender had been inevitable without the atomic bomb. He added that justifications of "military necessity" will "never erase from our minds the simple truth that we, of all civilized nations . . . did not hesitate to employ the most destructive weapon of all times indiscriminately against men, women and children."

Just weeks after Japan's surrender, an article published in the conservative magazine Human Events contended that America's atomic destruction of Hiroshima might be morally "more shameful" and "more degrading" than Japan's "indefensible and infamous act of aggression" at Pearl Harbor.

Such scathing criticism on the part of leading American conservatives continued well after 1945. A 1947 editorial in the Chicago Tribune, at the time a leading conservative voice, claimed that President Truman and his advisers were guilty of "crimes against humanity" for "the utterly unnecessary killing of uncounted Japanese."

In 1948, Henry Luce, the conservative owner of Time, Life, and Fortune, stated that "[i]f, instead of our doctrine of 'unconditional surrender,' we had all along made our conditions clear, I have little doubt that the war with Japan would have ended soon without the bomb explosion which so jarred the Christian conscience."

A steady drumbeat of conservative criticism continued throughout the 1950s. A 1958 editorial in William F. Buckley, Jr.'s National Review took former President Truman to task for his then-current explanation of why he had decided to drop an atomic bomb on the city of Hiroshima. The editors asked the question that "ought to haunt Harry Truman: 'Was it really necessary?'" Could a demonstration of the bomb and an ultimatum have ended the war? The editors challenged Truman to provide a satisfactory answer. Six weeks later the magazine published an article harshly critical of Truman's atomic bomb decision.

Two years later, David Lawrence informed his magazine's readers that it was "not too late to confess our guilt and to ask God and all the world to forgive our error" of having used atomic weapons against civilians. As a 1959 National Review article matter-of-factly stated: "The indefensibility of the atomic bombing of Hiroshima is becoming a part of the national conservative creed."

My, how "conservatism" has changed in the last 50 years! The same people who once correctly understood Abraham Lincoln; opposed the Civil Rights Act of 1964, Social Security, Medicare, and the whole "social safety net"; decried excessive regulation, spending, and deficits; and demanded realism in foreign policy now stand for precisely the opposite. Why shouldn't their views on the Bomb have changed, too?
