Meanwhile Corbyn is clinging to his post by using the same changed circumstances to oppose a new referendum while simultaneously saying, "See what happens when you break solidarity?"  Thirty seconds after Boris's airdrop, Brexit Tories call for a vote of no confidence, which every other party is happy to support, and Boris becomes the shortest serving PM in modern times.  The Tories fracture because they can't go on old-boying their way around the fact they despise one another, Labour fractures because it just can't help itself, and the UK spins into US-style gridlock.

Scotland forces a divorce from the not-so-UK, and threatens to build a Great Wall of Haggis if anyone in the South doesn't get the memo.  Scotland then tells a tragically desperate Northern Ireland, "Yeah, thanks, no, we've got our own problems you know."  And Northern Ireland looks south.  Hard Orange resistance, Hard Green retaliation, and Irish Alzheimer's are likely to put some blood in the streets, but since it is now possible to distinguish between the Republic's legal code and Canon Law, the swing voters are more likely to vote for cash than creed.  With a Taoiseach who is something more than a ham sandwich, the Republic could actually unite the island, and Ireland could be a modern version of what it was in the 6th and 7th Centuries: a light in the regional darkness.
