Well who’s balls are on the line? I assume the people that bought them or invested in them. The way I see this Ukraine situation, is Europe and the western part of Ukraine is broke. (because of imports, and too many gov’t jobs with benefits and pensions)
Eastern Ukraine is probably a wealthy area, and Europe wants to absorb it to help with expenses. The Russians in eastern Ukraine probably know better, and don’t want to be married to a Europe with too much baggage. 🙂
And naturally, why would Russia want to lose a wealthy productive area, and or lose that port they historically owned in Crimea where they have bases? Re defaults? The good thing about them is the currency value drops in value, making imports too expensive, domestic production grows, and exporting excess production easier.
