The concept of a sovereign country has been for the most part deemed obsolete in Europe. Maybe that's a good thing. Only time will tell. However, by nature mankind is very territorial, it will be interesting to see.
If the older countries of Europe are broken up, it would be easier for a centralized regime to govern. Places like Wales, Scotland, Catalonia, and the Basque country would be less populous than the countries from which they would secede and are thus more likely to be submissive to the European Union than Britain or Spain.

Not that many years ago down in Greece, my uncles talked about “the Europeans” and of “going to Europe”. Now my nephews and younger cousins think of themselves as thoroughly European. Greece can still be “tribal”, especially out in the countryside, but the whole “European” thing has really caught on among the educated, professional class. That attitude isn;t a good thing, in my opinion, but the fact is that Greece has really picked Western/Northern Europe’s pocket when it comes to development funds. The Greeks have made out like bandits with EU grants and it really shows, especially in infrastructure improvements and general prosperity.
