I voted UK by the way... as of yet, the United States has no chance of breaking up. England and Wales basically just decided not only to say f**k you to Europe.. but also to their own union.
That's certainly not what current Scottish polling suggests, but our Union was probably done in the long-term regardless of the June 23rd result. I actually consider 48% and 16-odd million for Remain to have been a good result for them given how unpopular the EU has been for decades here.
Anyway, Colombia is the correct answer here and would be getting far more votes if the situation there were as well-known as the UK and US situations.
And, fwiw, NI has a next to nil chance of leaving.
