An old controversy
I am no peacenik but I have always been disturbed and skeptical over the A-bombing of Japan by a Democrat President. Japan was already crushed by that time
According to most high-school history texts, the bombing of Hiroshima and Nagasaki were terrible but necessary tragedies. They "ended the war," and while they resulted in the deaths of as many as 250,000, they saved many thousands more. Of course a close examination of the facts reveals that none of this is true: Even the estimate for a full-scale invasion of Japan put the American death toll at only 46,000 (all combatant deaths, not civilians). Moreover, the Japanese government had been trying to surrender – balking only at the unconditionality the US side demanded, as they did not want to see their emperor dethroned and executed. Following the Japanese surrender however, the US government happily allowed the emperor to continue serving as a figurehead.
Even the United States Strategic Bombing Survey declared that,"… certainly prior to 31 December, 1945, and in all probability prior to 1 November, 1945, Japan would have surrendered even if the atomic bombs had not been dropped, even if Russia had not entered the war, and even if no invasion had been planned or contemplated." Indeed, the devastation the US forces had wreaked upon Japan through conventional warfare (the infamous firebombing campaigns left as many as half a million dead) had already helped seal Japan’s defeat. The most generous interpretation possible of the motives for dropping the nuclear bombs on Hiroshima and Nagasaki is that they served as a demonstration to the Soviet Union of US military might.
