I think some Americans are shocked when they realise there are other countries. I've spoken to American adults who have said to me "why aren't you at work?????? it's 11am!!!!!!" -- when it's actually 5pm where I am, they had no idea that their time wasn't used all over the world.
As for ****ing up countries, "Britain" haven't had the most friendly past but that was a different world back then.
Britain should be the term associated in this thread. It's complicated.
