You forgot the amber nectar Scotty, which is the UK's biggest export apparently.
But really- what do you mean "is it workable?"
This is what happens after 300 years of negative propaganda. Nobody has any doubts but ourselves (which I suppose is quite healthy in a perverse sort of way...
What have Denmark, Finland, Norway, Ireland, Sweden, Netherlands, New Zealand, Belgium, etc, etc, etc got that we haven't?
The fact is, whatever you think of the SNP (and I don't have much of a regard for the party and its people, compared to the 70s), Labour have got into a knot and are losing the intellectual argument against independence, or 'divorce' or 'separation' as they call it. When Blair was forced into devolution by the will of the Scottish people (and even then tried a referendum which it was hoped would fail), Scottish Labour were forced to spout about how the SNP would try to 'wreck the parliament'.
What a dim idea that was. If the parliament was seen to work, obviously Scots would want more of it.
So George Robertson's perception of devolution as something to 'kill nationalism stone dead' was completely wrong.
The only reason Labour want to hold on to Scotland is, they'll never win an election in England without us. The only reason the British establishment want to hang on to Scotland is a strategic one, ie the Americans would have nowhere to keep their missiles and control the North Atlantic (and don't forget all the Scots who have been happy to sign up for the British forces, out of proportion to their population). So if independence comes closer, look for the CIA getting involved and bumping off a few of our top people.
Whatever happened to Willie Macrae I wonder?
