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?
While that it is definitely true, her reasons would be that it is easier to control and weaken the EU from the inside than from the outside.
