As a European I would say there is a stereotype that Americans are ignorant of world politics, geography and customs. But that is likely just a stereotype. Every nation looks after its' own concerns above and beyond those of other nations. I would say that America is tarnished from its foreign policy of recent decades - the cowboy attitude.
My own experience of Americans on vacations and meeting them in this country (at uni, work etc) has generally been very pleasant. Most are extremely polite, interested and genuinely wish you a good day (something lacking in my part of the world)
There are likely individuals that do ignore or dismiss everything that isn't the USA, just as there are individuals that go the extra mile to change national and international attitudes of, and towards, the US
