My thoughts exactly, but there is no face saving way for Putin to end this war. Ukraine has made it clear that it will fight until it has recovered all occupied lands, including Crimea, and the US and EU have pledged to support Ukraine for as long as it takes; further, since Putin has clearly demonstrated he has no respect of any treaties or laws, no peace treaty is possible without a guarantor of peace, and there is no possible guarantor but NATO. This means in order to negotiate peace with Ukraine, Putin would have to withdraw completely from Ukraine and drop his objections to Ukraine becoming a member of NATO.
