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?
Sure. There’s an application process; supposedly they can apply. It will take years, with a lot of conditions, and none of the previous exemption they had.
