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?
That’s exactly the problem : you need to fix your country before you can join again. That’s how democracy works.
The brexit is a tragedy, and I feel for those who didn’t want to leave the EU. But it’s done. Maybe your kids will be able to see the return of the GB into the EU.
