“The Islamic State of Iraq and al-Sham (ISIS) is the victim of a US-Saudi decision to get rid of the ISIS burden and rehabilitate the Islamic Front as a final substitute for the Free Syrian Army (FSA). The US-Saudi plan aimed at replacing the FSA with the Islamic Front started a few weeks ago with attempts by US Ambassador Robert Ford in Antakya, through meetings with Ahrar al-Sham, Suqour al-Sham and Liwa’ al-Tawhid Brigades, and the most prominent leaders of the Islamic Front, to persuade them to return to the FSA General Staff, whose headquarters and weapons stores near Bab al-Hawa they seized, and to join the political process in Geneva.”
