Another proof that Brexit is one of the best thing that ever happened to the EU.
We are finally moving forward without the UK blocking any further political integration.
We've also lost a strongly pro-market and pro-trade country
.
I've grown much more supportive of the EU overall (I never supported a Nexit or something like that, but I used to be pretty negative about the EU), so if this causes European armed forces to become more efficient I strongly support it. NATO remains our primary safeguard (and should be expanded), but liberal democracies working together on defence matters is a good thing.
