LeMay’s greatest strength as a commander wasn’t a subtle grasp of the historical, political, or psychological aspects of an enemy.
He was pretty sure he was bombing Hobbits, to be entirely honest.
Perhaps not literal Hobbits, but his understanding of the enemy was a few stereotypes each, if that much. Germans were efficient, dull, and didn't feel pain the way we did. Japanese were crafty, devilish, and didn't feel pain the way we did. Italians were amazing lovers (of people, pizza and pasta) and didn't feel pain the way we did. And Russians ate potatoes covered in Russian dressing, and didn't feel pain the way we did.
