Ok, so what does that entail? I don’t think you can just jump on TV and call peace. Ukraine has stated many times that they will not agree to any peace deal without the boarders going back to 2014, russia has stated that will not fly.
Even if you assume its a full on meat grinder for both sides, how does russia win in this situation? They claimed this military operation was to de-milliteraze Ukraine, the opposite has happened. They claimed this military operation was to put a stop to NATO expansion, the opposite has happened. They claimed this military operation was to protect the Donbas people, now they are the group who has suffered the largest casualties in this conflict. They claimed this military operation was to ensure the russian people prosperity and security, the opposite has happened.
