I think the Russians want to be rid of Galicia. Once Lemberg and its hinterlands are gone, the whole thing becomes much more manageable.
The (really, really) big question in all of this is, once it becomes clear that Ukraine in its present form is finished, is Germany going to cooperate in rearranging the pieces on the board between the Oder and the Dnieper?
Lemberg was never really Polish (Lwow only lasted a few years). Maybe it can become an EU protectorate? That really depends on whether or not Putin is done once the Ukraine thing is over, or whether he wants the Baltics, too.
If he's content for Estonia and Latvia to be in the EU, he'll probably be fine with Galicia being in the EU as well.
Russia is quite content to divide Ukraine. It would rather keep it under its thumb but barring that it takes the spoils in NovoRossiya.
The West can figure out how to prop up a bankrupt Kiev and Lvov.
And with winter fast approaching, the real fun is just beginning.

In his books (which you can find for free, don’t send the guy money) he talks of letting that sliver of Russia on the Baltic to Germany.
I fear that Dugin’s works will be remembered as the warning no one wanted to see.
Lwow had been part of Poland for centuries.
