No Korean took part in Pearl Harbor. It's the CCP and the Communists who want the Americans to think of their allies as enemies.
Assuming that you're an American (but I think you're just a troll, or have a different agenda), how would you feel if a Korean wouldn't forgive you for selling Korea to Japan? Although I'm not a Korean citizen, I read a lot of the history and I can read Korean. The fact is, the US and Japan were friends when Japan occupied Korea. The US' wrong decisions played a part in Korea becoming Japanese territory, and later Korea becoming divided.
