The EU will never go anywhere so long as the UK is a member. Britain's consistent policy over centuries has been to play "balance of power" politics to keep the countries on the continent divided and equal in power. The idea of a united, strong Europe is most unwelcome to London. Europe has to figure out how to get the UK out, and how to get the Ukraine and Russia in.

If the UK leaves, the economy collapses. Period.

The Netherlands won't be very far behind UK, and then Finland and the Swedes, I think pretty soon it will just be the ones who are getting the most from the EU budget. All of a sudden they will realise that the money isn't coming in and it will all fail.

Europe has to figure out how to get the UK out, and how to get the Ukraine and Russia in.
To an extent that "Europe" is synonymical with Huntington's "Western civ", admitting anything non-token from "Orthodox civ" [in Huntington's nomenclature] would be suicidal for Europe.
