Well, there's also the most likely scenario. It's the same one that arguably ended the Soviet union: The war goes on for decades or more, with growing desperation on both sides. The Russian economy bleeds through any loose change under the couch cushions to build more tanks & artillery. Ukrainian resistance sustains a long term insurgency against the occupiers, using essentially the same tactics as the Mujahideen or modern Taliban. The West slowly stops caring as other "breaking news" pushes this down the front page. Years of war bankrupt the central government, and regime change deposes Putin. American and British companies come in and privatize anything left. The country is left in poverty and austerity. And then the same thing more or less happens 30-50 years later...
