We had no other choice.
It was either drop the bombs, kill a few thousand people or not drop the bomb, the war lingers on and more people die than the bombs killed. WW2 had to stop and this made it happen. Neither country could afford any more warring on the other, this was a costly expense. True we killed innocent people, but if we didn't more would have died at the hands of the Japanese and of the Americans. The bombs not only made sense, they saved lives. Despite taking some.
