The president of the think tank Richard Haas chaired the panel of distinguished participants — Stephen Hadley, Prof. Charles Kupchan, Alina Polyakova and Lt. Gen. (Retd) Stephen Twitty. It was a great discussion dominated by the liberal internationalist stream that has so far guided President Biden's national security team, which wants to help Ukraine fight a long war against Russia. 

The striking thing about the discussion was the acknowledgement candidly articulated by an ex-general who had actually fought in wars that there is no way Russia can be defeated in Ukraine, and, therefore, there has to be some clarity as to the stated endgame to "weaken" Russia. The gloomy prognosis was that European unity apropos the war is no longer holding. 

Third, one plausible scenario would be that Russia turns Ukraine into a "frozen conflict" once the current phase of the war reaches the administrative boundaries of Donbass, connects Donbas to Crimea and incorporates Kherson and a "strategic pause and a stalemate in the not-too-distant future" may open the door for diplomacy.
