The problem is that the vast majority of Americans are totally ignorant of anything that isn't happening within their immediate neighborhood. Sure, most of them have
heard of Canada, Mexico and Cuba, but few could point them out on any map that didn't have flashing neon labels. There are Americans who cannot tell you if Canada is to the north or south of them. More to the point they don't
care about not knowing. Is it surprising that so few Americans know anything about Australia, or even where it is, when they don't care about Australia, or anywhere else outside their immediate vicinity?
