You know, I find all of the westerners who are critically obsessed with Japanese culture quite funny. You get a bunch of people who run around watching import anime (without a clue what they're saying), wearing the most ludicrous tee shirts just because they have kanji characters on them, and constantly talk about how when they "grow up" (snicker) they're going to move to Japan.
And how none of them seem to be aware that the Japanese are not even a tenth as tolerant of foreigners as Americans are. How the Japanese will never accept them. And none of them know that the Japanese laugh at people who are obsessed with their culture, and look on with derision as they spend a fortune trying to suck up a culture they'll never be a part of.
Being proud of the Japanese for their actions in World War 2 isn't something you should be doing. Period. They were friends with the Nazis for a reason, pal: Similar ideals.
Know what they did to Commonwealth POWs? Know what they did to the Chinese in the areas they conquered? Medical testing. They infected them with viruses and diseases, then vivisected them. Live dissection. The Americans let the Japanese war criminals off the hook in exchange for medical data, and then downplayed this fact to avoid a public outcry (The Commonwealth is still waitin' for them to apologize... oh, wait, no, they're too proud to give us that, even after the Americans beat the crap out of them).
There are still WW2 survivors from Japanese death camps - people who were infected with scarlet fever when they were just teenagers. Do you think they were happy with what happened? Do you think the Japanese were "honorable" in their rape and slaughter of the entire region?
The Japanese did hideously evil things during WW2, and the US covered up those hideously evil things (and even did a few experiments of their own to boot. Boom.) I don't blame you for not being proud of the US, but if you're going to be proud of a people for what they did in WW2, be proud of Great Britain. They fought off the Nazis alone while the US didn't want to get involved. They lived in the country and had to go about their lives as civilian targets were being bombed. They survived.
