As a Canadian, could it be rebranded to Western Democratic Union (or something), so we can join? Also it might help UK undo its mistake if it didn't have to admit its mistake.
There are at least a half a dozen countries in the EU with 1000 years of history behind them. I wonder how that weight of history blends with what the modern world requires.
I don't think so. Of course it's hard to predict what Europe will look like in 100 years, but I'd like to image the EU more as a service provider for its member states. Maybe the military will be combined and the economy is already very much linked together which will increase. But I don't think the member states will cease to exist as sovereign nations. Europe is far more diverse not only in language but also in culture. That is in my opinion a strong feature of the union as it is a union in diversity.
