Change is horrible and expensive, and you have to find all kinds of new ways to solve your problems. But if the SNP and Labour did win, and we got a de-facto break up of the UK, with the deterrent scrapped and all kinds of Greek-style spending decisions - there would be a rebalance.
In the in/out referendum the rest of the UK did not get a say. I'm sure that in the aftermath of a Scottish highjack, devo max +++ would probably be insisted upon by the English electorate. Think of the benefits:
We could hand back all the "foreign" MPs - like Galloway.
We could let them have the 2 mahoussive carriers; originally future proofed and built large for catapult operations - now excessively large for VSTOL ops.
We could build and base all our own ships and submarines etc etc
But that would be very unfair on the majority of Scots who did NOT vote for the SNP in the referendum.
Surely such decisions are subject to a debate in the House - and an awful lot of jobs rely on the industries threatened.
