I’m surprised with all the sturm und drang of the brexit vote reaction in Scotland, it seems like everybody has missed entirely the easiest way for Scotland to rejoin the EU without a messy period of independence. It could apply for admission to the nation of Ireland based on their common historical roots.
The likelihood of this actually happening given the political stars of today is approximately zero. What I find interesting is the reason why the idea is so far out there that it wouldn’t even be brought up. If an independent Scotland has difficulty making a go of it, why is a Scotland tied to the English and out of the EU superior than a Scotland tied to the Irish and inside the EU?
