In mid-August, a well-connected Syrian activist drove to the border city of Gaziantep in southern Turkey to meet two officers from the CIA. The officers had set up shop in a conference room at a luxury hotel, where representatives from a handful of opposition groups lounged in the lobby, waiting for their turn at an audience.

The activist, who had been a journalist before the conflict, came with three colleagues from Aleppo, the Syrian commercial capital that had recently turned into the main theater of the war. Inside the room, two casually dressed Americans were rolling up maps from the previous meeting. The Americans introduced themselves as CIA officers and said they were there to help with the overthrow of Syria’s authoritarian president, Bashar al-Assad.
