American Troops Leaving Syria 'Raises Concerns Over US Commitment' To Allies

Gen Petraeus said: "It certainly does raise concerns about our level of commitment to the partners, who really did the fighting, and in many cases the dying on the ground, to eliminate the ISIS caliphate and to defeat the Islamic State as an army. "Keep in mind, there are still tens of thousands of Islamic State fighters in groups in north-eastern Syria... very likely trying to establish an insurgent movement as well as to still carry out terrorist attacks."
