On the surface, it seems the war against ISIS in Syria is going well. On August 12, the town of Manbij was taken by forces of the Manbij Military Council (MMC) and the Syrian Democratic Forces (SDF).
Then on August 24, the nearby border town of Jarablus was occupied by Turkish tanks and troops. Turkish forces were joined by Syrian fighters claiming allegiance to Islamist and other groups affiliated with the Free Syrian Army (FSA).
In both instances, the US provided air cover. However, there the similarities end.
