Whilst Russia is a country-mile from doing a Yugoslavia IMO, it does beg the question what would the likes of NATO, the EU and China do if it were to descend into civil war, with its various bits vying for control over its natural resources and nukes? If it came to some sort of sphere-of-influence carve-up, China could do quite well with the resource-rich eastern territories, Europe being left with all the lunatic-fringe territories west of the Urals...
