I like how you think that I have this opinion because I am missing some fact, or whatever - I know about the invasion plans, I am talking about other options ie non-military ones.
The Emperor basically wanted to still be Emperor after the war, which we ensured anyway, had we given such assurances prior, an invasion might not have been necessary at all. The Japanese were already discussing surrender.
Opinion of somebody who was there: "[...] the use of this barbarous weapon at Hiroshima and Nagasaki was of no material assistance in our war against Japan. The Japanese were already defeated and ready to surrender because of the effective sea blockade and the successful bombing with conventional weapons... My own feeling was that in being the first to use it, we had adopted an ethical standard common to the barbarians of the Dark Ages. I was not taught to make wars in that fashion, and that wars cannot be won by destroying women and children. "
And if you think that such use of nuclear weapons would be well considered, note that nukes were practically ready for Vietnam, because apparently Napalm wasn't enough.
