I don't see the conflict going on for years simply because Ukraine will run out of men to fight it. It NATO decides to send in troops that's WW3 and that definitely won't last very long.
Poland will take a chunk out of the northwest, Russia will take Crimea and the Donbass region of the southeast and what's left will be Ukraine and it will be a rump state under the influence of Russia,...much like Belarus.
I hope you are right.
WW3 seems very likely now. As per the NWO/international bankers, Russia must be destroyed. If our village idiot is told to order nuclear missiles he will do it. Without congressional approval and without warning.
Russia has already had its Bolshevik revolution. It won't allow the one occurring in the U.S.A. to come into Russia without going to war.
