I do not understand the reasoning behind making nuclear weapons a moral question.there is no evil weapon only evil uses.What is the difference between droping thousands of conventional weapons on a city or one nuke? You can question the reasoning behind bombing "civilian" targets but it should not metter if it was a nuke or thousands of conventional weapons.I hate to say this but even if the only reason was to intimidate Stalin thats a good enough reason.The Soviet Union was one of the most evil intitutions man has made and anything that could have been tried to reign them in would be a good idea. you can't judge decisions made 65 years ago with our godlike hindsite,even if the japanese were ready to surender if we didn't have a way of knowing why take the chance? all side bombed the hell out of cities throuout the war to judge one of them at the end differently just because it was "a big scary nuke" dosn't make much sence to me.
