"The Turks and their allies in Saudi Arabia and Qatar would like to rebrand the Jabhat al-Nusra and Ahrar al-Sham, movements, whose beliefs and actions differ little from Isis, as born-again moderates."

This may explain why Isis has responded so little to the US-Turkish agreement that is supposed to deal it a crippling blow."
