As long as the West supplies Ukraine with weapons, the Russians will eventually be moved out.
If Russia is not moved fully out (because of some kind appeasement), this culture will continue to assume that it "owns" Ukraine. The Russians need a big paradigm shift .
Other powerful nations need the same kick in the ass, but that's another discussion.
Russia is a fragile state that has become more fragile. When it collapses, the war in Ukraine will end.
Expect a several million ethnic Russians in Ukraine to willingly or unwillingly leave for Russia. Crimea and Donbass will no longer be dominated by a pro-Russian political landscape. The west will cast their eyes aside on this exodus.
And China may take over territories in the Russia's far east.
