I’ve spent a lot of time in the Balkans, and one interesting real world equivalent to this domain is that a lot of older ex-Yugoslavians, especially ones that went abroad in the 90s, still identify themselves primarily as Yugoslavians and not as Serbians, Croats, etc. Maybe a bit of it is nostalgia, but I think a similar thing might happen if America broke up into separate countries. You’d still have a sizable amount of people that identify more as Americans than as Californians/New Yorkers/etc.
