I recently became much more pro-total-unification, so let me give you this counterpoint: individually, European nations are no match to the major superpowers, neither economically nor militarily. We'll get gutted by divide-and-conquer approach. In contrast, bound much closer together (particularly with some form of pan-european armed forces), the EU would become a proper global superpower and a counterbalance for the USA and China.

There is not a single example of a multiethnic or culturally diverse empire or state that was successful after the rise of nation-states at the end of the 19th century.

All of them crumbled either peacefully or in bloody wars.

Why do you think such a bureaucratic monster that no one really wants would be an exception?

Maybe we can try it again in the 24th century, when the humans evolve enough, but for now, your best bet for a successful country is either an ethnonational or religion-national state.

You cant really believe any of the EU countries actually want to work together? The EU was only possible with the premise of countries keeping their autonomy. Believe me when I say that us Germans would rather go to war than merge with France, just as an example.
