It's not as stupid of an idea as it sounds, and it is part of our history. I don't think they should do it, but people need to understand that the Japanese were pure evil. It's not like "Americans are bad, Japanese didn't deserve it", they deserved it, we saved millions of lives from not having to invade and killing everything that moves on Japan's main island.
No nation of millions is "pure evil." That's the kind of absolutist rhetoric we were fighting against. I'm on record here as supporting the a-bombings, but it is not something to celebrate.
