What I heard is the reason for the question is economic, should Scotland go down with the Euro and EU debt, or survive with their Pound Sterling, and cope with the inefficiency of exchange between two financial systems.
There’s also the question of defense. If they do not have the rest of the UK to rely on for defense, what are they going to do? Grab their daggers out of their socks and attack?
In addition, ALL of the UK’s nuclear capability (supplied by the US) is located in Scotland. This is going to have to be moved to England and will be a massive disruption of defense in general, their economy, and international relationships.
Maybe it’s dawning on them that there’s a lot more to this independence stuff than they’d considered. Scotland is the most Socialist part of the UK, and also has a very high Muslim population, and I’d say those two groups probably had a lot to do with the independence movement to begin with.
