Russia would be fighting against many independence movements and people across the country would riot. The orthodox church and probably all mosques would condemn the decision and Chechnya would go mad.
I would be happy. Wanna know if I need to pay some extra money/taxes to get a decent pension or sit and relax and travel more around the globe knowing that I will drop dead before having to face "old-age proverty".
What if Scotland, Northern Ireland and Ireland decide to form a "Celtic Union" = form an independent state?
