Sy Hersh has a long piece in the London Review of Books detailing the strong evidence indicating that the Turkish government worked with Syrian rebels in a “false flag” operation of the worst sort: staging a chemical weapons attack near Damascus in August 2013. The intent was to throw blame for the attack on the Assad regime, thereby drawing the United States directly into the conflict; the use of chemical weapons against the rebels was a “red line” repeatedly laid down by Barack Obama as the trigger for an American intervention.
