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?
Yes, the bombings of Hiroshima and Nagasaki were justified
The bombing of Hiroshima and Nagasaki cost civilian lives. However, ultimately it was for the greater good.
For Truman, the bombing of Hiroshima and Nagasaki was justified
The way WWII played out meant that the bombings were the most effective ways of ending the war, preventing further destruction.
