What? Pre-invasion estimated where over a million in casualty. The Japanese were willing to fight down to the last man/woman. They were arming their civilians with bamboo spears.Are you serious? The Japanese military was obliterated by that point, it was completely unnecessary. All that was needed for Japan to surrender was for us to tell the Emperor he wouldn't be killed, which we did anyway, after the bombings.
The bombings were 100% Truman waving his dick.
