If Scotland (not the SNP, which is the mistake made here and elsewhere) votes Yes, independence will kick in long before any relocation of Trident. Immediately, Western Europe's main nuclear deterrent will be located in an independent, non-NATO country. A bargaining chip? Like or loathe Alex Salmond, he's got more political nous than Cameron, Miliband and Clegg put together.
At the moment, I'm voting No. I don't have enough information to vote for such a radical change. But I understand the Yes argument. There is another argument up here that runs like this. One cannot be reasonably asked to make a Yes/No decision lacking the details. Therefore, once they are known there should be a 2nd vote.
