We’ll give the
last word to University of Maryland professor of political economy – and former Legislative Director in the U.S. House of Representatives and the U.S. Senate, and Special Assistant in the Department of State –
Gar Alperovitz:
Though most Americans are unaware of the fact, increasing numbers of historians now recognize the United States did not need to use the atomic bomb to end the war against Japan in 1945. Moreover, this essential judgment was expressed by the vast majority of top American military leaders in all three services in the years after the war ended: Army, Navy and Army Air Force. Nor was this the judgment of “liberals,” as is sometimes thought today. In fact, leading conservatives were far more outspoken in challenging the decision as unjustified and immoral than American liberals in the years following World War II.

Instead [of allowing other options to end the war, such as letting the Soviets attack Japan with ground forces], the United States rushed to use two atomic bombs at almost exactly the time that an August 8 Soviet attack had originally been scheduled: Hiroshima on August 6 and Nagasaki on August 9. The timing itself has obviously raised questions among many historians. The available evidence, though not conclusive, strongly suggests that the atomic bombs may well have been used in part because American leaders “preferred”—as Pulitzer Prize–winning historian Martin Sherwin has put it—to end the war with the bombs rather than the Soviet attack. Impressing the Soviets during the early diplomatic sparring that ultimately became the Cold War also appears likely to have been a significant factor.

The most illuminating perspective, however, comes from top World War II American military leaders. The conventional wisdom that the atomic bomb saved a million lives is so widespread that … most Americans haven’t paused to ponder something rather striking to anyone seriously concerned with the issue: Not only did most top U.S. military leaders think the bombings were unnecessary and unjustified, many were morally offended by what they regarded as the unnecessary destruction of Japanese cities and what were essentially noncombat populations. Moreover, they spoke about it quite openly and publicly.
