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?
I doubt u could reunify without mass deportation or genocide of half the population I think the best option is becoming our own country and joining the ru before reuniting. Sure no ones happy at first but it’s the only way to keep the peace.
