Yeah, I think if they can hold it, it makes a lot of sense.
I would add that I imagine that it’s also a pretty strong psychological strike against the morale of Russian soldiers.
Personally, I’m typically outside the mainstream on the war in Ukraine (I’m more skeptical of the unquestioning supply of aid by the US than most people), but I think that strategically, this makes plenty of sense. And as much as I really hate war or loss of life even by the aggressors, I can’t help but wish to see the kind of progress that forces Russia to end this insane, disgusting folly of an invasion as quickly as possible.
