I am not so sure that the answer to the outright question will be no, I think a lot of people think there is not an alternative for Scotland due to ineffective opposition, some of the things that are happening south of the border are scary!! I think although the Olympics were amazing, the total spend is going to come back and bite Cameron & Co on the backside as the recession hits harder and harder. It has been publicised that the money that has come in from the Olympics is no where near what was envisaged by retailers etc.
I work for the NHS and although there are a lot of things wrong with it, there are a heck of a lot of things right with it and am glad the SNP place it high on their agenda, as down South it remains to be seen whether plans to contract out etc will go ahead which if it does will be the first step in it's demise.
It is such a big decision for our nation and there is a lot more information to be read yet before people can decide. I used to be a life long Labour voter until the last couple of years when I defected to SNP not due to the independence thing but because I believe they have done a lot of good for Scotland and for the Scottish people. I love Scotland and everything it stands for and would hate to see it spiral into something uncontrollable, I am a proud scot and always will be whatever happens.
Interesting that you think the answer to the outright question could be yes. Maybe you and I talk to different people because most of the people I know and have spoken to about independence simply do not want it but would be happy for an alternative option for the very good reason that you state at the end of your post, i.e. the fear that it could all spiral out of control. I said in an earlier post that I greatly admire Salmond as a political leader, even if he is a devious individual at times (what politician isn't?), but that he wasn't going to be around forever and that there is nobody in the SNP, or indeed any of the other parties, who comes anywhere near him, therefore under a weaker series of leaders an independent country could well become uncontrollable.
However the one thing that a lot of people don't seem to realise is the fact that independence could never happen overnight. It would take possibly years for a number of major issues to be sorted out, probably the greatest being the Constitution - will Scotland become a republic or still regard the Queen and her descendents as Head of State? - and the inevitable wrangling could itself lead to independence being strangled at birth.
Equally many Scots who are shouting for independence seem to be unaware that Scotland is in fact already quite an independent country. Thanks to the endeavours of the Scottish Parliament when the terms of the Treaty of Union were being thrashed out in 1706/1707, Scotland was allowed to keep its own Church, its own laws and educational system, and add to that the fact that the present parliament has its own devolved powers, one of those being, as you say, control of the NHS.
Ultimately though the final decision to overturn the Act of Union would have to come from the Parliament of Great Britain, so unless a yes vote was overwhelming, which is extremely unlikely, Westminster could simply refuse to allow this to happen.
