> It's been a long time since I've read it, but I'm guessing the saving lives part of dropping the bomb.
I wasn't baiting an argument about the bombs, but I just don't want to let it slide by. That is with almost certainty a false claim. I know we don't admit in America that we are capable of producing and consuming propaganda, so it's exceptionally difficult to communicate that idea despite what facts & what leadership at the time said that is in the historical record. Something swept under the rug was that there were many senior military leaders who pleaded to not use the bombs on urban, civilian population centers, at the very least. Also contrary to popular belief, the Japanese leadership was actually desperately looking to find a way out of the war. It was over by that point. Hirohito had no way for his empire to survive, and he selfishly did not want to relinquish his role as emperor (he otherwise offered to surrender if he could).
Feynman wasn't a military general at the time and he likely had no way or time available of knowing the full consequences of use of the bomb.
My high school history textbook told me that the bombs saved lives. President Eisenhower said there was no reason to drop them. There are two sides to that story.
