Actually I heard from my late father the real reason why the Japanese attacked us. In the late 1930s a Japanese ship visiting Pearl Harbor invited some US Marines aboard for a reception. The booze, it seems, flowed freely. The Marines made derogatory remarks about the Japanese, assuming they didn’t understand any English...but they had someone who did. The reason my father knew about the incident was that he was one of the Marines.
Goodness! I hope they didn’t call them Koreans!
I’m surprised, given pre-WWII American-Japanese relations, that any Japanese ship was making a port call at Pearl, or that they would have been allowed to do so. It’s not surprising though, that Marines would have acted the way you say. Relations were very bad between the two countries at that time.
