The Japanese that I have met are *unfailingly* polite and *unfailingly* courteous. Refreshing.
And fearless.
The one story about WWII I ever got out of one of my Grand Uncles was of holding his M1 Garand with rags on the fore-end because his barrel was so hot, it was burning through the wood. He had a *deep* respect for the Japanese. As I do.
Unit 731 was an atrocity. Nanking was an atrocity. Ever read "Fly Boys"? One particularly sadistic Jap Colonel would cut the living organs out of pilots and eat them raw, before their dying eyes. Horrible. Good read.
