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?
The EU didn’t exist at all back then. Today, the EU can make such a demand of a new joiner, say for instance the United Kingdom, because it’s the entire EU vs UK. In 1992, it was Voltron coming together, and they needed that left leg lion to keep him upright.
