Does Brexit weaken the EU? Thus far, in the form of Ireland and the backstop, it's been handed a massive opportunity to demonstrate how it will stand by all of its members, big or small. Take Sweden as the example - its UKIP equivalent has recently dropped its calls for leaving the EU, short-term at least, while polls in Sweden show that support for membership has strengthened since the start of Brexit. Plus, for eu-enthusiasts, seeing the back of the troublesome semi-detached UK isn't necessarily a bad thing.

I think a lot of people assumed brexit would mean a crisis for the EU. It's not working out that way. The only place with a political crisis is the UK.
