Neither side is winning, both are losing. The win for either side is different. Jomini of the West says it best: https://pbs.twimg.com/media/FZM0k5OWAAE2wml.jpgMy main worry us that if further attacks of this nature continue with the Ukrainians receiving intel and other forms of assistance from their NATO backers; the Russians might take things to a new level. How they perceive things and how things are perceived by their opponents can differ greatly.
If we look at the popular narrative: it's of a demoralised Russian army which has suffered tremendous losses being on its last legs in the face of stiff enemy resistance; massive Western support and a Russia hard hit by sanctions. I question widely held narrative. People routinely claim-- with justification - that Russia can't win but I'm asking if the Ukrainians can win and what a win will really look like.
