I'm seeing a lot of this utopian idea of a Scotland free of the tyranny of the terrible English and I find it faintly ridiculous vision.
On the point you mention quoted above for example; that was a set of decisions undertaken by a government who were nicknamed 'the Scottish Mafia' in some circles due to the amount of Scottish that held the powerful positions in that government. Scottish MPs were a large part of taking us back into Iraq. So while you doubt an independent Scotland would have gone in to Iraq, I say the only thing that would stop you would be a lack of a sizable standing armed forces - it certainly wouldn't be your Scottish MPs.
My point being, MPs are MPs, the are in general self serving egotists who always have one eye on the next election and by their nature plan for the short term so they can keep the power they enjoy. They pander to the electorate that is going to give them a majority (hence the way Tony Blair's Scottish Mafia took Labour away from the socialist left).
Scotland is not going to get some new breed of politician because you're independent, in fact it's odds on that most of your MPs will be the very same arseholes that have sat in this Parliament.
What is quite scary is the current vogue of lowest common denominator politics and again, it is prevalent on both sides of the border. Up there you have Salmond - all chest beating and anti English sentiment while refusing to be drawn on actual answers to policy questions; while down here we have scumbags like Farage - all tweed and bitter down the pub, talking like Jeremy Clarkson and finding some kind of foothold while displaying no substance.
One other thing to think about while dreaming of the brave new tomorrow is that the MPs you already have are already doing what Salmond is claiming will happen in the event of a No vote. They are slicing up and selling off the NHS to foreign investors. Surely they are not the same MPs that will be fair, transparent and lead Scotland into something new and inspiring.
