I don’t have any good examples that I know of, but I am very curious. To me though, a rivalry is a rivalry when two or more of people are closely competitive. But is it really a rivalry anymore when someone has more victories over the other? I don’t think so.
France and UK. UK still thinks they’re competing like the old empire days, but France basically just does not care about them/is barely aware of them.
France is all about Germany ever since we got married to Germany with Merkel
