I'd love to see a united States of Europe in my lifetime. I don't think it will happen but it's a beautiful dream.
Thinking it would end nationalism is utterly deluded though
Retroarnold . There's this little country called the United States of America, you might want to read up on it.
Especially this. How on earth do you see this working? How do you plan to stop people calling France, France? That's before you even get to the nations that don't even "exist" but still have nationalists. Cornish nationalists, Sicilian nationalists, Cretan nationalists, etc.
