Sure we would. It's like a tooth-gap - and there's also the issue of lacking a respected military in times that are getting a lot more... interesting.
But it feels like the UK needs to do some domestic cleanup before that has a chance of happening. Seems like the UK media and political landscape has gone completely off the rails.
Or just individually leave the UK. I find the thing kind of depressing. It's not even as if the leave voters seem happy. It seems more of a my life's crap - lets destroy this EU membership thing - oh my life's still crap. Apart from Boris - at least he got to be PM and seems fairly cheerful. Perhaps the lies on a bus were worth it.
Or to campaign to leave the UK - which I suspect is a more achievable and sensible option. I'd doubt if the EU would want the UK back anyway.
