As an American, I don’t find the concept of independence from Great Britain particularly frightening :P While it certainly be best if it can be done peaceably, I somehow have some doubts as to the sincerity of the English in acquiescing to Scottish independence, especially if they are the ones counting the votes.
Let's analyse it. One million Scottish voters, out of a total electorate in the UK of just under 50 million, could basically destroy my country. I live in the United Kingdom of Great Britain and Northern Ireland. If Scotland opts out, the United Kingdom ceases to exist, and there's nothing I can do about it. I don't get a say, I don't get a vote, I don't even get asked my opinion. And this is democracy in action? How would you feel about it if a section of America were to do something like that? Well we know how - there is no Confederacy any more, is there?
