Yet they didn't surrender after we destroyed their navy, they didn't surrender after Germany fell, and they didn't surrender after we took their outer Islands and threatened invasion. Instead they fought to the last man with whatever they had, ontinued Kamikaze attacks and prepared school children for invasion. Sounds like a very reasonable enemy to me. Yet you say there was no reason for an invasion, even though Japan had made no meaningful strides towards surrendering even after it was clear to anyone that they had lost the war.

I guess we should of stopped beating up on poor ol' Japan by that point, and hoped they learned their lesson. Hell, even after the second bomb destroyed Nagasaki, the Japanese militarist faction refused to surrender and Emperor Showa had to break up the deadlock.

So I don't see where you get the idea that there wouldn't have been an invasion, and a deadly one at that if we hadn't dropped the atomic bomb.
