Just think - if the world took off the shackles and Ukraine no longer cared about the moral high ground […]

My issue with this assumption is that removing moral shackles from one side of the war, the other wouldn’t care so much afterwards either. In practice this would mean that Putin would think of using nuclear weapons far more often than it would be okay. I believe this war has an element that is kind of like a careful dance around the red button that could destroy most of Europe, if not the world.
