We were talking about this in US history during this last summer school...

In my opinion, I think that it was dropped for the reason of speeding up the war. If we had not dropped it, the war would be more costly in American lives and American money.

Basically, Truman saved more American lives, but the Japanese were substituted to make Victory in Pacific.

Though, at this point because of island hopping methods, we did trap the Japanese onto their original homeland... but I'm ONLY guessing that maybe the same amount of lives lost in the bombings would happen in "general" warfare if we didn't.

But I don't think a second bomb was really necessary...

I also think the idea of Pearl Harbor kind of comes in mind with the choice of bombing. The Japanese did a surprise attack with bombs and airforce in Hawaii... so the idea of revenge may come back up?
