At this point both sides have lost the war. Russia won't come out more powerful even if it takes everything it wants to take at this point, and Ukraine is going to be beaten, bloody, and reeling for a decade even if Russia left today. There is no world in which this war has a winner, it's just a matter of deciding what all is lost, and Russia needing /something/ tangible to justify it all. It's horrifying in every possible way the word can be envisioned.
