I expect them to surrender. Fighting with no hope of resupply and reinforcement is criminally senseless. There is no point in a fight you cannot win.
This splendid little war from Moscow’s point of view is all but over. Whether it expands depends on other developments in the days ahead.
I haven't seen any indication that they want to fight the Russians. At least not the Crimeans, and probably most in eastern Ukraine. They don't want to go with the westerners and become socialist subjects of the Euroweenies.
