That about sum it all. My situation allow me to follow closely similar situation in Belgium and Spain.
Separatist parties mine the emotional level. The reality is that splitting countries with intertwined economies and population for generation is impossible to predict and generally require plenty of good will from one side or the other.
About everything Scotland bets on for its future need happy cooperation from the UK and Europe. From Europe point of view, it lacks the framework to support splitting countries and EU countries are wary enough about their sovereignty that it would be difficult to predict how they would react. On the other hand, for the UK, at the end of the day, that's a little slice of 10% of its population that decided to keep their resources for themselves. 10% of the population deciding what happens to the other 90% is exactly what Scotland is complaining about Westminster and London. On the other hand UKIP and others are fond of that message when applied between the UK and EU.
What a mess.
