Should Scotland be an independent country?

I see your point, but I'm sure that plenty of Londoners would be quite happy of we could cut ourselves off from the rest of this country and float off somewhere a bit warmer - but that's just not the way it works is it?

No, but I refer to the point I made earlier about 'nations' (not necessarily a state). Or 'peoples', for want of a better term, who come to define themselves in terms of a different language, ethos, history, shared identity and so on. This commonality can sometimes lead people wanting to define their own piece of physical territory (i.e. a state) that is separate and distinct from the larger part of where they are now.

In theory, in time, London could define itself as an independent city state.
But its identity, language, ethos, history and so on, are tied up with England, and unlikely to happen.
Scotland is different, whether you like it or not...
