Japan said no to surrenduring after the first nuke.The Japanese were merciless warriors. I'm sure they would have dropped as many as they could to effect surrender.
There's nothing different or "special" about America that caused us to drop a second one. The prospect of losing another several hundred thousand of our own men to defeat Japan was reason enough to throw another one. And we would have thrown a third in September or October, I'm sure.
We must never forget that it's easy to Monday morning quarterback decades later. The decisions that were made were made by people who were weary and shocked from 4 years of global warfare brought about mostly by Germany and Japan. It had to end by any means necessary.
War is about ruthless destruction of the enemy. In later wars the US showed the world what dipping a toe in the waters of war does. Korea, Vietnam, on and on we go. Our "police actions" and limited engagements yielded nothing but protracted, unecessary suffering.
Once you're in, you've got to be all-in. The one with the most resources, and will to win, is the one who prevails.
Correction. The soviets DID invade manchuria with millions of men and 5000 tanks. This was a big part of their surrender since they had a 2 front war going on.The Soviet Union also declared war on Japan after the bombs dropped; they were going to invade Japanese occupied Manchuria.
Thanks, I think I'll look it up when I drop by the bookstore.Tom Clancy wrote about a new war with Japan. It was called Debt of Honor
