[Hatredcopter]

Finally a voice of reason here. It's not like America was sitting on a mountain of guns and tanks, just waiting to use them after their Allies got the tar beat out of them for a couple of years. Unfortunately I don't think "facts" work on Tenchu, really. He'll likely just brush them off, claim you didn't understand what he was talking about, and continue hating Americans as a whole based on his own convenient knowledge of history. Anyone who thinks they know anything about World War II without knowing about the atrocities Japan committed in China during that time doesn't actually know anything about World War II. That doesn't exactly directly relate to America's entrance into World War II, but you get the idea.
