I hope for a small core of countries that further integrates their military, which can then later be joined by other countries. If smaller countries like Belgium, Netherlands, Denmark, Norway, Ireland (+ Scotland after their independence) got together in the near future and instead of each rebuilding (I suspect their armies have all been severely underfunded in the last 2 decades) their army separately, build one stronger new army, then they would all be stronger for it.

The eu as it already exists could use some fundamental rule changes to deal with internal abuse. Orban has been a pseudo dictator for years now, and he just needs 1 other eu country to side with him to shield Hungary from real consequences. So what’s especially needed is more democracy and less veto powers.

Things like education, culture, social welfare, … are imo better done on a regional level and thus should not be fully integrated.

Edit: I added the “fully” because I think it would be good for the eu to set out a standard framework for compatibility and/or minimum standards, but the actual implementation should be left to the regions imo.
