Hank's comments are actually a question, and one that we should always bear in mind. To pretend there wasn't incredibly intense racial animosity involved in our war in the Pacific ignores history. My grandmother, the daughter of two German-speaking, kraut making immigrants, had no love for the "Japs" and wasn't shy about saying as much. The fact that during WWI her own father had been subject to boycott and abuse as a German immigrant didn't seem to phase her. He ultimately trained himself to use an English accent and pretended to be English, though the town knew better ;-) I'm happy the government didn't round my people up. If they had I wouldn't even be here, of course. So looking back on it I can really see how unfair we were to the Japanese. We should have been clear that we were making war on the military junta, not the people as a whole. But we did quite the reverse.
It's something everyone needs to keep in mind during the present wars, as well. It's all too easy to slip into hatred of Muslims in general as the enemy, which is the point I believe Hanks was trying to make.
Sorry for going OT, but I have to defend the fellow typewriter collector. Attacking Tom Hanks is like kicking a puppy ;-)
