Read 'Quartered safe out here' G. MacDonald Fraser for a view on how down and out Japan was.Japan was down and out for the count when Little Boy made his entrance.
LeMay had already written to the Joint Chiefs telling them he was going to be out of anything of any worthwhile size to bomb by the end of August and would be down to using his B-29's bombing very small towns and villages. He was already throwing 400 B-29's at a time at towns of 50,000 in July.
Remember, the target cities had been off limits to conventional bombing so they would be good test targets.
You're presumably too young to have been offered the chance. I notice you don't say you wouldn't have either. Which is at least honest.I definitely think I'm better than any nazi. I have never loaded my fellow citizens into a gas chamber, for instance.
