There are all kinds of permutations as to what will happen on May 7th, but the frightening thing is that almost all of them end in Scottish independance.
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.
