All I'm saying is that it makes sense for Ukraine to maximize its territorial gain before the inevitable Russian counterattack. More land = more time. If Russia plans to repeat the same tactic of slowly pushing upwards, regaining Kherson will allow Ukraine to hold off Russia for a few extra months and even if they do re-capture Kherson in the counterattack, it will be a Major Pro-Russian city left in ruins. Throwing lives away is only negative if you do not achieve your strategic objectives, which with the recapture of Kherson, will be a major strategic goal in cutting off the water supply of Crimea.The point is a river of bodies does not work in the Ukraine case. While, actually, in any case, if there is no other work to improve their status. Bodies can do nothing. Only well-organized people, not dead people, can make things done.
Is it possible for Ukraine to restore its military industry to sustain its war? Is there any western country focusing its industry productivity on military equipment while supporting Ukraine? Do you know that the USA is calling for help on military production because they do not have enough artillery shells to supply Ukraine Amy? So do tanks and other armored vehicles? No need to say that the Ukraine Army is dealing considerblely fewer casualties to Russians in nearly every battle, which shows that even with the help of Nato, they still can't beat Russia at its weakest point, as you say, in the current state.
Ukraine can also sustain this level of war, even if you take the maximalist level of Ukrainian losses, they can mobilize millions of men, what's a few hundred thousand in the grand scheme of things? We're decidedly still NOT at WW2 levels of mobilization for either side.
