There's a running joke that my state (Texas) should secede from the U.S. and frankly it's the most capable state to do so, but I always point out to people that it would be a Brexit situation of having to renegotiate all our trade, but that seems better than being a Tax-donor state (we send more money to the Federal government then we get back). It's really just a meh situation as the U.S. continues to slowly fall from its hegemony, but as 2016 pointed out, all a rival country has to do is promote some sectarian facebook pages and Americans start fighting each other and burning down towns (lul).
