That's a strange requirement considering the executive of most EU states is not directly elected by people either. Do you not consider Germany or Italy to be countries?
At least, it's usually the leader of the party the people voted for in the legislative elections.
In the EU there was this Spitzenkandidat idea floating around ten years ago, but it was never enacted in texts and died at the first opportunity (naming Von der Leyen back in 2019 when she wasn't the leader of the PPE), because the heads of members states (particularly the French) weren't willing to give up their designation power.
In practice there isn't even European political parties, the European elections are just national elections represented by national parties and most citizens don't even know the names of the European coalition of parties (PSOE, PPE, Renew, etc…).
My point was that accountable democracy requires direct vote from the people and not via second hand, not that Germany or Italy aren't countries. And if EU wishes to be a country it needs that level of direct accountability which is impossible.
Otherwise if you force it it's gonna be another Yugoslavia or USSR where most people are pissed because they're not being ruled by someone of their own culture that they can directly vote for.
These forced multi-culti nation states under one roof abominations don't work. It's been known since the Tower of Babel yet the elite ruling class think this time it will be different because it worked in the US, a country younger than most universities in Europe.
Theseus' ship? Isn't that "Umvolkung" nonsense again? Philosophy, political sciences, and law have have rummaged about these questions for the last few centuries and have developed some pretty good answers. Of course, they are mostly not simple and all too long and intricate for this forum, but I guess you can pick up any modern book on theory of the state to get your answers.
But I get the distinct notion that you have a certain idea what a country, state, or nation is, considering the conflation with culture, and it is not very embracing of pluralism. I'd wager you'd like Schmidt, maybe Zippelius, but not Böckenförde.
No, I wasn't talking about "Umvolkung", it was a genuine question.
Isn't that "I'll low-key call you a Nazi because you asked a question about a thing that vaguely resembles what Nazis talked about" nonsense again?"
