From my very limited outsider's perspective, Brexit seems very American to me.
Y'all don't like being a part of the EU, paying taxes to them, yadda. So y'all want to leave. And y'all are fortunate enough to be able to leave democratically and peacefully. We had to fight for our independence and pretty much invent Western democracy on the fly, y'all. (Y'all Count: Four.)
Anyways, I'll excuse my very ignorant American ass out of the conversation. Good luck with your big Cabbage Patch Kid PM, or whatever he is.
