Like any country's thought that they themselves are exceptional: immature.
We were, but a lot of us have begun to think we are Europeans.
It is a sick, foolish, concept. I have seen this among people who are not well traveled, or who travel to places that are self-contained and never see another country.<br />
There is much that we can learn from other first-world nations. What exceptionalism is doing is creating sheeple that work harder, with fewer vacations and no health care, because they do not know any better. The only exceptional thing about America is that we are actually winning THE RACE TO THE BOTTOM.
Unwarranted and delusional.
Religious arrogance and ignorance.
Not a lot a the moment, considering they are so poverty stricken have such low wages and their democratic leaders do diddly squat ...
