http://www.reuters.com/article/latestCrisis/idUSWBT011299hello all, I'm in Japan right now, about 4 days ago I visited hiroshima and had a chance to visit ground zero and the peace museum. There's many factors surrounding the decision to drop the bomb and the decision to drop 2 (remember they were a few days apart) and they were both against non-military targets. also let us not forget that the fire bombing of tokyo killed far more than either of the bombings. History is written by the winners and had we lost the war we would have definately been tried for war crimes related to the fire bombings.
several other factors related to the bomb dropping was to force japan to surrender on our conditions not conditions more agreeable to them. Also after the european campaign russia agreed to enter the japanese theatre and we wanted to hasten a surrender so that russia did not have any time to enter and claim anything. Additionally we dropped 2 bombs so that we could prove that it wasn't a one trick show at the time we only had 4 bombs worth of fissible material (if i remember correctly).
The argument that dropping the bombs was much less deadly than a full blooded invasion is very much true, but the japanese already were close to surrender at that point. it would be impossible to say for sure if we would ever have been required to fully invade japan.
anyways that's all i have for now, I got to visit the Toyota plant and it makes so much sense why they are beating american auto manufacturers. Today i'm trying to work out a tour of a japanese facility that does a lot of welding, have a nice day!
