I think it will end in a ceasefire. The concern the west has with this war is that if Russia were to invade another country and then annex territory from that country it would throw out the rule book and international law would be meaningless, it would mean any nation would be free to take land from any other nation. While yes, other countries have taken land from one another post WW2 it has never been recognised or legitimate. If Ukraine acknowledged the surrender of land in a treaty that would legitimise it.
So I think the west would prefer an end to the war that saw Ukraine de-facto hand over land but to not officially acknowledge it as lost. Though there will probably be stipulations on that ceasefire, like a promise that Ukraine does not join NATO and a limit to the amount of arms that the west can send them. But the conditions of that ceasefire will of course depend on how the war ends and how badly the Ukrainians lose.
