> I know that hypothetically the whole of the U.K. getting into internal conflicts equal to The Troubles in Northern Ireland (my gut says 5% chance of that) could be utterly devastating to the entire fabric of the nation… but that hasn’t happened yet If I had to guess, I'd say the conflict is much much likelier to come back post-Brexit. Now that we're out of the EU, the "open movement" hack made possible by mutual EU membership no longer works without knock-on effects (customs checks, blah blah). I can't see Boris Johnson falling on the sword to safekeep the peace in NI, so if the push comes to shove, NI is more likely to be left to fend for themselves.
