To those who read my post and misconstrued it. What I stated was that it is agreed that without the bombs Japan would not have surrendered. I should have stated unconditionally, but that is historical fact that before the bombs use the US threatened them with complete destruction if they refused to surrender unconditionally. That threat was ignored. The use of the nukes lead to a fast surrender that stopped the war in it's tracks and created the nuclear deterrent we have in place now. Which it could easily be argued, prevented a likely war between the US and the Soviet Union at the time.
Was the decision to use the bombs right, I have no idea, nor did I make a claim about that ethical decision. I think this article outlines the overall problem from both sides pretty well. http://www.ushistory.org/us/51g.asp
As for:
"Less than a hundred thousands"
@Flum, the initial studies done do suggest the deaths of hundreds of thousands. Further studies suggested numbers ranging from 1-4 million american deaths and 5-10 million Japanese before the end of the war. Throw in some other facts like the Japanese commanders had issued the threat that any invasion/blockade of Japan would lead to the massacre of 100,000 POW's, and near all of them were returned alive after the use of the bombs. Then the claim that this was a clear cut case of the bombs being wrong is a bit harder to say. Throw in the added facts that the Japanese had been fighting to the last man and women and even committing suicide instead of surrendering, and suddenly conventional warfare doesn't seem all that likely to have lead to a low death toll.
Again, no idea if the bombs were right. Nobody can know that for sure. But on the same note, nobody can know they were wrong for sure either. Claiming otherwise like you are doing, is just playing make believe. Which is why I refrained from making a judgement and stuck with the fact that prior to the bombs surrender had been refused despite staggering Japanese defeats and after a surrender quickly ended the war.
