I'm not jumping for joy either (being currently in the UK, as one of those all-guilty EU migrants), but here's a silver lining.
I've had the privilege to witness the Czech-Slovak divorce in the early 90s. It was scary as hell. It was in fashion those days to start a bloody war wherever communism was falling and there were more than one nation. Freedom this, freedom that, you just feel like you're sitting on a warehouse full of dynamite and no one knows where that one spark might fly in from. Czechoslovakia held a referendum. There were way too many people who voted pro separation, despite being very open about their desire to stay together. They simply agreed to let them go in peace if they feel they want to, rather than ending up in another of the early 90's countless local wars, such as the Balkan conflicts or the break off of Soviet Union. The separation that followed was one of a kind in its hystorical context. More like a civilised divorce, it cost some more money, created some more useless burocracy and paperwork but overall, no end of the world. After no more than 5 years everyone agreed it was stupid and whatever, Czechs like beer and so do Slovaks.
I don't think it really matters now if they're right or wrong. What I appreciate is that all this can be done without blood. It's a privelege that goes unnoticed by many, it seems. Especially these days.
