All of these talks are completely useless without Kiev agreeing to give up territory as any other outcome will not be acceptable to Putin and Russia is currently dominating on the battlefield. Frankly, I don't know why Putin would accept anything less than an unconditional surrender at this point. I still think the most likely outcome will be a partition of Ukraine with the Lviv/Kiev section being de-militarized and administered by a 3rd party. I originally thought that 3rd party would be Poland but I don't think Putin would agree to that any longer. Every day that goes by gives Kiev less leverage in negotiations. I think actual talks will only start after Putin takes Odessa and Kherson.
