The Price for Western Aid is Ceding Russia More of Ukraine
Donetsk and Luhansk is now Russian, and the land around Mariupol is also now Russian. Whether Putin will settle for that at this point depends on his mood
Zelensky will inevitably declare to his people that they have been sold out by the West, that they gave up their nuclear weapons for nothing - that Ukraine will be broken up, and may eventually lose its independence, regardless of how much Ukrainians are willing to fight.
This is in spite of Zelensky's current position that: "There can be no compromise on the sovereignty and territorial integrity of Ukraine and will not be"
Neo-Conservative voices are seemingly fixated on how Putin is losing the war in Ukraine; that Putin underestimated Ukrainian resistance.
