I don’t think they will want to stop at that. NATO would probably support pushing it back all the way. Otherwise the troubles are just going to drag on for decades. I guess this is where resolutions in other wars were found. Push into Crimea and other territories to bring Russia to the negotiating table and then end the war with the pre 2022 border and a UN peace force. I’m drawing comparisons with the Korean War and the 38th parallel from WW2 (the split between where the Japanese surrendered to the USSR and the US). During the Korean war the US and South Korea pushed all the way up to the China/Russia border which then forced them to surrender and negotiate a split of the country at the original WW2 parallel.last thing I read was Russia considers Crimea Russian land, so that’s a delicate one. I think a win for Ukraine is pre 2022 land recaptured
