With all due respect...sometimes I do have the sensation that average Americans (pardon my bluntness) don't really give a damn about us Europeans.
That is...about our politics...whether American decisions taken in Washington DC affect us Europeans or not. And how.
And this hurts...because United States of America was -allegedly- founded by Europeans.
Well, yes, America was founded by Europeans - who had reasons for wanting to leave Europe and separate themselves politically from the affairs of that continent. By the same token, America's Founders didn't want America to get involved in European affairs or play favorites among European nations. We wanted to remain neutral, not so much because we didn't give a damn, but more to protect ourselves.
During the 19th century, Europe was going through various wars, turmoil, and discord, while the US was involved in expansionism on our own continent and pushing towards the Pacific Rim. At that time, it wasn't really feasible for the US to get involved in European affairs, and we figured they could handle their own problems anyway.
It wasn't until the World Wars that America started to become more of a major player in European politics, and we tried to stay out at first. I think there's a combination of American chest-thumping pride that "we saved Europe twice," along with an underlying resentment at having been dragged in to two world wars in the first place.
That may be where a lot of feelings towards American exceptionalism come from, since Americans born around or after WW2 have been brought up to believe that America is indispensable to world freedom - the so-called "defender of the free world."
But there are also quite a number of Americans who have clearly grown weary of America in this role. It's been an unnecessary and unfair burden on the US taxpayers to have to feed the military-industrial complex which provides the means for fulfilling our role as world's policeman.
