Admittedly, I don’t know much about Brexit, but from what I have been exposed to, it seems like a decisively economical and political impairment that made travel and business with the rest of Europe more difficult and costly. Since it is so highly criticized as a terrible move, why doesn’t the UK just rejoin the EU?
It would be smart, but their pride forbids it. Besides, when re-joining, they would start off like any other member, not as privileged as they were before thanks to Thatchers blackmailing. And they would have to ditch the pound in favor of the Euro, which would be the most painful thing.
But on the long run, they will have to come back. It is not a question of “if” but just “when” if they want to survive, and the longer they take, the more painful it will be.
