Visitors to the National Air and Space Museum—America’s shrine to the technological leading edge of the military industrial complex—hear a familiar narrative from the tour guides in front of the Enola Gay, the plane that dropped an atomic weapon on the civilians of Hiroshima 70 years ago today. The bomb was dropped, they say, to save the lives of thousands of Americans who would otherwise have been killed in an invasion of the Home Islands. Hiroshima and Nagasaki were largely destroyed and the lives of between 135,000 and 300,000 mostly Japanese women, children, and old people were sacrificed—most young men were away at war—as the result of a terrible but morally just calculus aimed at bringing an intractable war to a close.
This story may assuage the conscience of the air museum visitor, but it is largely myth, fashioned to buttress our memories of the “good” war. By and large, the top generals and admirals who managed World War II knew better. Consider the small and little-noticed plaque hanging in the National Museum of the US Navy that accompanies the replica of “Little Boy,” the weapon used against the people of Hiroshima: In its one paragraph, it makes clear that Truman’s “political advisors” overruled the military in determining the way in which the end of the war in Japan would be approached. Furthermore, contrary to the popular myths around the atomic bomb’s nearly magical power to end the war, the Navy Museum’s explication of the history clearly indicates that “the vast destruction wreaked by the bombings of Hiroshima and Nagasaki and the loss of 135,000 people made little impact on the Japanese military.”
Indeed, it would have been surprising if they had: Despite the terrible concentrated power of atomic weapons, the firebombing of Tokyo earlier in 1945 and the destruction of numerous Japanese cities by conventional bombing had killed far more people. The Navy Museum acknowledges what many historians have long known: It was only with the entry of the Soviet Union’s Red Army into the war two days after the bombing of Hiroshima that the Japanese moved to finally surrender. Japan was used to losing cities to American bombing; what their military leaders feared more was the destruction of the country’s military by an all-out Red Army assault.
The top American military leaders who fought World War II, much to the surprise of many who are not aware of the record, were quite clear that the atomic bomb was unnecessary, that Japan was on the verge of surrender, and—for many—that the destruction of large numbers of civilians was immoral. Most were also conservatives, not liberals. Adm. William Leahy, President Truman’s Chief of Staff, wrote in his 1950 memoir I Was There that “the use of this barbarous weapon at Hiroshima and Nagasaki was of no material assistance in our war against Japan. The Japanese were already defeated and ready to surrender.… in being the first to use it, we…adopted an ethical standard common to the barbarians of the Dark Ages. I was not taught to make war in that fashion, and wars cannot be won by destroying women and children.”
