Still feel terrible that Ukraine fights on their own as far as the human risk in this conflict. They've proven themselves the opposite of a lost cause like the former Afghan government, or further back the Republic of Vietnam, who were governments with little actual support of the population.
If Putin gets on TV and already tells his people that they're fighting the west, how escalatory would it even be if that were simply made to become reality? Or to look at it from a different angle, would the costs of Ukraine losing/having to agree to a stalemate without parts of it's territory also not be an unsustainable peace? I think that Russian aggression would likely reoccur within a decade at most.
I think there's a mismatch in terms of the strategic significance of this conflict (indirectly will define the security situation in Eastern Europe for a decade or longer, implications for global security) and the current commitment of US/NATO resources. I think the deployment of aerial, anti-air, logistics support, intelligence, and any other sort of units short of armor (explicit commitment not to violate Russian territory with ground units and no use of strategic bombers) to support Ukraine should be considered. Even while I know that the actual answer is that none of this will be considered or done.
