Personally, I think the current strategy is to capture Donbass (specifically Donetsk oblast) with newly mobilized men as soon as possible, declare victory, end the S.M.O. and mobilization, and hunker down for a decades-long border war, with natural barrier along Dniper river or fortified defensive positions along the new border. It's more sustainable way for Russia to continue the conflict in the long-term too, rather than endless mobilization and onslaught against Western Ukraine or Kharkiv, which only plays into NATO's strength in endlessly funding a porcupine for decades, with no guarantee that Ukraine would surrender or be conquered. The S.M.O. can largely be a success in achieving it's limited strategic objectives, but mixed results on broader strategic front.
