he premised the case by saying that Trump would do nothing, and with that premise his best case was that Russia and Assad took back all of Syria. He said he thought the likelihood of that was around 1%.

He did not advocate US troops on the ground, but rather thought the Dempsey plan of training a Syrian force of 10,000 for a year, arming them, and backing them with air cover was a credible plan. Basically what we did in Croatia in 1993 / 1994. This plan was abandoned by Obama inexplicably, according to him.
