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?
Why would it not be in the interest of the EU to make an example? Poland and Hungary were (led by extremist right political parties) playing with the idea of leaving the EU, too. I think it has become mighty quiet on that front now that they have seen how much of a pain it is for the UK to empty a whole magazine into their own feet.
Same for France and Italy. Nobody is making loud noises about leaving the EU anymore.
