Mission accomplished! Good luck with, well, everything & looking forward to seeing you in back in the Union within 2 generations! Without the prior exemptions & special treatment, naturally.
Most EU countries have an ultra-right wing, nationalist and euroskeptic party in their parliament (I just don't want to say "fascist"). At least three (Italy, Hungary and Poland) have one in government. In France, Mme Le Pen has consistently got to the second round of presidential elections for the last ... three? Four? elections?
Things aren't going well.
You mean might be a new union? I can agree with that. A fragmented Europe is not stable, if the EU dissolves in the next 10 years, it's almost certain there will be some sort of union in the next 2 generations. Whether there'll be another war in Western Europe between now and then is another question altogether.
Leaving was their 'controversy of the day', there are other ones they can use to pent up dissent.
