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.
While the Japanese Army in WW2 was more brutal then Western non-political Armies as they really didn't have Western norms and values about warfare using terms like evil to describe an entire population is decidedly unhelpful.
Concepts that an entire population is evil is a thing of ugly wartime propaganda and its best left there.
