Turkey is not fully satisfied with the joint operations center set up on the Syrian border in cooperation with the United States. In Turkey's view, the center restricts a comprehensive, all-out operation east of the Euphrates against Kurdish forces that Turkey considers a threat to its national security.
The Turkish-American joint patrols began Sept. 8, yet the depth of the area under patrol does not match Turkey's expectations. The Turkish government led by President Recep Tayyip Erdogan has insisted on a safe zone with a depth of 30-40 kilometers (18-24 miles) while also articulating a new target: to transform the entire east of the Euphrates — from Raqqa to Deir ez-Zor — into a “peace corridor,” and to transfer 3 million refugees from Turkey to the safe zone.
