So the UK should become part of the EU again. BUT the EU need to take away some veto rights, namely from France, Italy and even Germany.
For instance, France has been cockblocking a trade agreement with South America, citing "environmental concerns". Fact is it would introduce competition against some of Frances industries - effectively screwing European growth.
Maybe Schengen countries should step in to mediate the situation.
There should at least be a path to a more democratic vote, where each country gets a certain amount of votes to equalise each other out.
So that France can stop our trade deals? No thanks. We'd rather pay for priveliges than do that. So we won't join, and the UK won't come back.
Simple as.
