I agree with the nuking of those 2 major cities.
During that time many of the adults of Japan were in support of the war AND there were major military factories that needed to be disposed of.
I don't think it was a good Idea because of the children though.
If we hadn't bombed those cities it would have been harder to make Japan surrender or Japan might have won the war, and to be quite honest I'm GLAD that I'm not speaking Japanese because our superiors didn't decide to bomb those cities.
So regardless of who was down there, it was the right decision.
