My point is that we stopped the war. How much longer do you think it would have gone on and at what price? How many more Japanese Dead? How many more Americans? Chinese? Korean? Islanders? Until there is a parallel universe, we can't know. War is hell of course. But, we probably differ on what constitutes a war crime. And, no fair retroactively applying definitions that have relatively recently been invented to things that happened 70 years ago. It was a different time. We are different people. While there have always and will always be "moral laws" (at least one hopes)  'international law' was a fledgling concept.. I hope nothing like it ever happens again.

Interesting article from the Atlantic about "what if?"
