Of course, these "extremist groups" who "espouse a militant vision of Islam" and are "sympathetic to Al Qaeda," describe the "Islamic State" verbatim. ISIS constitutes NATO's mercenary expeditionary force, ravaging its enemies by proxy from Libya in North Africa to Lebanon and Syria in the Levant, to Iraq and even to the borders of Iran. Its seemingly inexhaustible supply of weapons, cash, and fighters can only be explained by multinational state sponsorship and safe havens provided by NATO ISIS' enemies - primarily Syria, Hezbollah, Iran, and Iraq - cannot strike. DW's report specifically notes how ISIS terrorists regularly flee certain demise in Syria by seeking safe haven in Turkey.
One of NATO's primary goals since as early as 2012, was to use various pretexts to expand such safe havens, or "buffer zones," into Syrian territory itself, protected by NATO military forces from which "rebels" could operate. Had they succeeded, DW camera crews would probably be filming convoys staging in cities like Idlib and Allepo instead of along Turkey's border with Syria.
