Salmond's campaign amounts to this. He wants the Scots to vote for independence, cry freedom and all that. Then, having told the English to get lost, he will the morning after the result pop up demanding negotiations with the remaining bits of the UK. He wants to leave, and then stay. Having scrapped the Union, he will be seeking another union.
The Nationalist assumption is that the snubbed English (more than 90 per cent of RUK) will play along sweetly, perhaps in return for Salmond allowing Trident to remain on Scottish soil, which would drive many anti-nuclear Nats nuts. He also wants a currency union in which he will set about aggressively lowering corporation tax to try and remove jobs from England. What is in it for the English taxpayer? Not much.
It is hard to disagree with Iain Martin's analysis:
