I believe it is factual to say that the fire bombing of Tokyo prior to dropping the bomb on Heroshima killed significantely more civilians.
Nagasaki of course was a secondary target and was very near not happening at all due to clould cover and low fuel. I am not sure of it's military value. I completely support the bombing versus losing thousands of men if invasion was required. It was total war in Germany and Japan. Difficult to reconcile today until the time that an idiot uses a hydrogen bomb.
Nagasaki was the secondary target as a shipbuilding hub with Mitsubishi weapons factories. The cloud cover over Kokura (a more desirable target) was too bad that day. Also - there was the fact of the hilly terrain around Nagasaki that would increase "blast damage."
I put this up there with things like the death penalty, which I guess we could say this was. Ted Bundy needed to go, yes. But I cringe at the circus atmosphere and celebrating with signs and hoots and cheers, too. I "get" the celebration of "this war is over", but I also suspect that like the Michael Douglas character in "The American President," Truman likely thought to himself, "This is the most unpresidential thing I do."
