Were the US bombings of Hiroshima and Nagasaki justified? Show more Show less
Back to question

Was President Harry Truman justified when he authorised the use of nuclear weapons against Japanese civilians? Did the bombings end the war with fewer deaths than an American invasion of Japan would have resulted in? Or was the bombing of Hiroshima and Nagasaki unimportant to Japanese military leaders when they decided to surrender?

No, the bombings of Hiroshima and Nagasaki were not justified Show more Show less

The bombings of Hiroshima and Nagasaki caused extraordinary damage, without even causing the end of WWII.

Nuclear weapons did not end the War, the USSR did

Soviet intervention in the conflict was much more important in ending the War in the Pacific.

The Argument

At the end of the war Japanese military and civilian leaders considered two strategies to force an acceptable end of the conflict. First, they could ask the Soviet Union, at that point not engaged in the War in the Pacific, to mediate terms of surrender between Japan and the Allies. Second, Japan could fight a final defence of the Home Islands so costly it would force the United States into negotiation. Both of those plans changed drastically when on 9 August the USSR entered the war on the side of the Allies. After quickly sweeping up Japanese units in Manchuria, the Soviets were poised to attack Japan from the North. The USSR entering the war and crushing Japanese forces in Manchuria so swiftly meant both options favoured by Japanese leaders were no longer viable. Japan could not ask the USSR to mediate a surrender if they were a party in the conflict. The military could not fight a two front invasion, particularly given how vulnerable the northern Home Islands were given the concentration on defence against American attack to the South.[1] Soviet intervention in the conflict rally brought an end to the war. Bombing Hiroshima and Nagasaki was not required to end the conflict and so not morally justified.
