I'm pretty casual with the expression "on tilt" because I occasionally play poker. If I managed to express something more than I meant to, I'm sorry for that.

I agree with you that our relationship with Japan after the war is pretty fascinating --- I think you could say something similar about our relationship with Germany! My takeaway from that is that we Americans should have a lot more humility about our own role in the world, because countries can turn on a dime from one pole to the other.

But one obstacle you'll have to pursuing that conversation in this thread is that a lot of people will read it as an attempt to downplay the disgrace of American concentration camps. Since those camps were very recently cited by American politicians as a rational for registering Muslims, it's a hot-button issue.
