I agree in principle as "nations" are a fairly recent development. Perhaps a better term would be "tribalism" as people like to belong and/or identify with a group - call it a tribe for lack of a better term.

Ideally, people would consider supra-national entities (such as the EU) as their tribe, but I wonder how far that will go. Even in a large country such as the USA, it is hard for everyone to identify as belonging to the same USA tribe, what with divisions of North-South, religion, race, etc.
