NATO aid and their not allowing Ukraine to negotiate peace is what is prolonging this war. We aren’t arguing for all of Ukraine to become Russian territory, which hasn’t been the position of the Russian Federation either.
We would like a negotiated peace that alllows the Donbas republics to leave Ukraine and join the Russian Federation as they’ve voted to do, and a promise for Ukraine to not become part of NATO. That senario is not the alternative you’re talking about, or what you’re implying we support.
