I feel like a protracted proxy war in Ukraine was never really on the table.
What we've seen so far is the US and its allies forcing Russia to pay a "price" for its adventurism. The value of this is both to act as a deterrent against future actions and to strengthen Ukraine's negotiating power when it ultimately surrenders.
I suspect that at a certain point everybody will be satisfied with the level of pain exacted, Ukraine surrenders, and Russia ends up with at least a large chunk of Ukraine.
