Re: In hindsight
the EU is a long story starting with In 1951, the Treaty of Paris.
Yes, I'm well aware of it's history, but you're taking my comment out of context.
The ECSC developed into, eventually, a European Community, which worked tolerably well. It was turned into the EU by the treaty of Maastrict in 1993, and that is where everything started to go downhill. The French barely accepted it, the Danes rejected it, and people in the UK didn't get a vote because it would clearly have gone solidly against it. If you're going to argue that Brexit should have been subject to a 2/3 majority than I would say that the kind of constitutional change implied by Maastricht should also have been subject to that, in all of the then-members. It would never have passed, and we wouldn't be in the current situation.
