Was the United States justified when using Atomic weapons on Japan? -

I am doing my history day project on this. My thesis statement is: quot;The United States of America and Harry S. Truman were justified when using the Atomic Bomb against Japanquot; I need primary sources, so I am using President Truman s diary entries. Any other suggestions? Thanks! Also please state your opinion with evidence. Thanks!

hello. the United States used the Atom Bomb, a weapon they were unsure would succeed. They knew how ferocious the Japanese were at ground fighting. (see Guadalcanall, the entire Island hopping they d already done). Operation whatever would been a very bloody event. The ugly success of the Atom Bomb was almost a blessing.

No. (t was an entirely political act to finish the war quickly before the Soviet Union could enter the war against Japan and gain Japanese territory. Deliberately killing thousands of women and children is never justified. The leaders of Japan were already discussing peace moves.

Militarily, yes. Morally, perhaps. Politically to scare Soviets, no.
