It often seems like a lot of Americans who were always told their country is the best are waking up to the fact that it was mostly lies but still have that "USA best" thing buried down in their subconsciousness from all the propaganda so they start to think the exact opposite is true.

Also explains tankies. "We were told USSR were the bad guys, we were lied to, therefore USSR must have been a paradise."
How do you explain people jumping out of windows then, smartass?
