I say let Ukraine split in two !
The Eastern industrialized two-thirds of the country are in the hands of Russian-speaking people, plus Crimea that is Russian (now, while it was once Tatar, Ukrainian in no way) would constitute a Russian-speaking state joining the Russian common market.
And Ukrainian nationalists would stay in the western poor rural part of the country, around Lvov, joining the EU (and NATO of course) that is going to indebt it heavily, forcing it to dismiss civil servants and privatize everything, and to sell everything to the big capital, just like in Greece.
