The EU visionaries want an EU empire from the Atlantic to the Russian border. I assume even they do not wish to push on to the Urals, well inisde Russia’s own territory, though sometimes rhetoric says otherwise. Recent events have shown just how difficult that will be to achieve.
In Scotland some want to split from the UK. The UK is relaxed about it and has agreed it will be settled by a referendum of the Scots. The EU is anything but relaxed, threatening an independent Scotland with no membership of the EU. The EU fears that a Scottish exit from the UK and the EU could create a popular precedent, likely to be followed by Catalonia. If both the UK and Spain were split, parts of the western edge of the EU would crumble. If Scotland left the UK, maybe England would be even keener to vote out of the EU altogether.
Meanwhile, in the east, the EU empire has pushed too far too fast to get the Ukraine into the EU net. Russia has preditably baulked at that, and has responded by seeking to split the Ukraine into a Russian sympathising area and an EU one.
The history of European empires, unions and currency unions is a history of instability and break up. An EU empire from the Atlantic to the Russian border is too big to be realistic. There will be several areas, regions or countries that do not agreee with this drift of policy. We are now seeing the costs of this vision, and the problems posed by the f0rces who disagree with it.
Let us hope the EU wakes up to the reality that a lot of people inside the current EU and its wider sphere of influence do not want to belong to a new European empire, before the actions of those straining to get out causes worse problems .
