Probably going to help make their damn rugby team even stronger too!

I don't know if there's a word for it, but pretty much every nation has at least one other nation that it traditionally looks down upon, usually one that to outsiders seems quite similar and which often have in fact strong ties between them. France and England are a classic example, though maybe a little odd in that it's mutual. (I suppose Argentina and Chile are similar in that regard--each thinks the other is categorically beneath them?) Sometimes there's a clear regional hierarchy, like U.S. -> Mexico -> Guatemala even though it's not necessarily obvious to all involved--U.S. has traditionally looked down on Mexico but doesn't have any sense of a hierarchy beyond that, whereas Mexicans might not care less what people in the U.S. think but certainly feel they're better than Guatemalans. Sometimes it's a non-transitive circle. It can be very complex, and it doesn't have to make any sense, though often it's a simple reflection of comparative wealth or prestige. But it's a universally understood phenomenon. There's the famous quote by Jean-Jacques Dessalines, leader of the Haitian Revolution, who circa 1804 called the Polish "the White Negroes of Europe", exempting them from the murderous extirpation of all white-skinned people in the newly independent state. Fast forward to the 21st century and British prejudice against the Polish (and specifically Polish immigrant laborers) is a major impetus for Brexit.

Anyhow, I've learned to be careful about equivocating nations or cultures. Saying something like, "country X seemed just as nice as Y" might rub someone from X or Y the wrong way.

It's all thinly disguised racism, of course. But it does pose an interesting woke paradox: what if all a nation has left is its prejudice against another nation?
