I have read ever book I can get my hands on about WWII in both the ETO and the Pacific and I have never seen anything that would indicate that any US service men ever intentinaly targeted civilians. I don't believe that any US fighter pilots ever even saw main land Japan unless they were POW's. And in the ETO the fighter pilots had too many military targets, too little fuel, and too little time to ever harass anything that wasn't military. Keep in mind that every time a fighter pilot pulled his trigger, an camera started running. If you know of something different I would sure like to read it.
I really did not make that up. You can see references to it in books written by pilots in the 357th Fighter Group, and 56th Fighter group.
We had carrier pilots strafing and pounding the crap out of Japan near the end of the war, flying fighters.
It wasn't considered a war crime at that point. How could they?

You need to read more books.
