Personally, I hope for Devo-Max, the Scots get control over everything except foreign and defence policy. The UK has many burdens that require it to have a strong military, particularly a navy, and it is of course well known that Scots provide some of the best in the British army.
If the Falklands were to happen again, would the UK have to fight alone, minus the Scots? The Irish already have a policy of strict neutrality, which basically means they freeload off the security provided by their neighbours. The UK will be struggling to shoulder the burdens protecting this country and the civilised world from what it is plain to see is an increasingly dangerous world. Scotland, for its part, will lose the powerful and influential soft power excercised by the Foreign office, which according to reports I have seen, is second only to the US in influence on the world stage. Independence would be a tragedy for Scotland, and would make life more difficult for us. We would see a diminished UK, and a Scotland that counted for nothing.
If Scotland leaves the union and the Tories decided to pull out of the EU, do you think there will be a USA/UK economic union (beyond what we have now)? Canada/USA/UK have more in common than UK has with the EU. IMO at least.
Blown it again! A Scotland that counts for nothing! Nice, very nice.
Will rUK keep the seat on the UN security council? Will other nations not think that the boil on the arse of Scotland should not have it? Where are the nukes going to be based?
