What's next? Western leaders whine about Putin, Putin ignores them, Crimea becomes independent. Despite all the controversy over the events in Ukraine, they're quite possibly the most tame out of recent events. So far no one has died in the "invasion".
I don't see any possibility of war, especially since a lot of Ukraine's military leaders are defecting or at the very least refusing to follow the new government. Besides if Russia wanted Ukraine that bad they would've invaded long ago... It's not like they've had their military there for hundreds of years...
