I seem to remember a show on the History channel. It stated that even as the emperor was sending the message for surrender, that elements of the Japanese military were attempting a coup to prevent the surrender. This was after the two bombs. A conventional strike by B29’s broke it up. The two nukes were the only way to prevent more blood shed.
Very, VERY interesting! There is so much more to all this than I realized. I learned next to nothing about it in school, but I tried my best to educate myself ~three years ago. But facts and details such as the ones that are popping up all over this thread are hard to come by. What a blessing this has turned out to be!
If you have a chance look into the Japanese secret weapons programs from the war. They were not too far from having a number of jet aircraft which would have turned our bombers into Swiss cheese.
