Both NATO and Russia may claim victory in the end.
Russia goals are to destroy the Uke armed forces and de-nazify Ukraine. Russia is well down a path to achieve those ends
NATO wants to keep Ukraine intact. Ukraine lost Crimea and the two breakaway States years ago. NATO might be able to hang on to present day Ukraine. Present day Ukraine is very unstable mainly due to the remaining NAZI’s within its borders
I think Russia also wants Odessa.
