There seems to be a mini cold-war brewing with regards to interpreting the outcomes of the Brexit vote: It's either the EU or the UK that's dissolving. One side must be wrong and it'll pay dearly for its wrong doings. Look, the author is even comparing the EU's dusk to that of the Soviet Union. So much for subtlety.
What about: It's 2025 and the EU and the UK will still exist, still trade with each other?
Britain's Anti-EU stance had a completely broader base than in any other country and for a much, much longer time anyway.
There is another option than either EU or UK dissolving. What about both? N. Ireland could vote to leave the UK and rejoin the rest of Ireland. Scotland could vote to leave the UK and remain in the EU. Meanwhile, Spain, Portugal, France, and the Netherlands could vote to leave the EU like the UK did. Switzerland's participation in EU treaties could get revoked. Belgium and Spain could vote to break apart based on their long-running internal divides. In the end, you might end up with a denuded UK and a denuded EU and a completely different map in Europe.
Scotland, most likely yes. But there will be a huge exodus of business from there to England. Not the other way around.
Also wales, again not going anywhere.
What you and many other commenters need to understand is that the populous/economies of the other countries in the UK are tiny compared to England.
If they were to leave, they would almost certainly get bullied in the EU.
The Scots who think they will be independent whilst being in the EU? I don't think so. They would get slapped down harder than a Red Headed Step Child!
