However, this analysis is hasty and inaccurate due to the following reasons:
The withdrawal of the Euphrates Shield forces from the three locations controlled which they captured from PYD less than 3 hours.
administration since 2013 has been repeatedly undermining Turkey’s national security interests by supporting the PYD-YPG in Syria and currently is threatening in retaliation for Ankara’s decision to move ahead with the purchase of a Russian air missile system.
The third portion of Syria’s civil society organizations operate in YPG controlled areas east of the Euphrates River and are directly affiliated with the Marxist Leninist PYD political wing of the YPG.
wants to establish a mechanism to ensure that the PYD-YPG is protected by a small international protection force by creating other safe areas where the PYD can survive.
in regards to the territory held by the YPG-PYD in the west of the Euphrates, as well as the presence of the terrorist organization in the regions east of the Euphrates.
Turkey’s assumption of control over the rest of its border with Syria is not only extremely logical, it is a vital aspect of finally eliminating the PKK/PYD’s ability to operate from Syria soil.
The most important part of the plan for Russia was to facilitate an agreement between the Syrian regime and the PYD to take over the YPG-led areas and to hand them over to the regime by restructuring the YPG element as an integral part of the Syrian military.
While being hesitant to take steps against the Assad regime, Washington has alienated Turkey by supporting PYD, the terrorist organization that operates mainly in Northern Syria.
From a strategic perspective, while Turkey wants to reduce the YPG presence wherever it is located, the US, including Trump’s himself, seems to protect YPG against Turkey’s upcoming military operation and to assure the long-term presence of PYD/YPG’s in Syria.
While Deash was cleaned off from Turkey’s border with the Euphrates Shield operation in 2016, the PYD pocket in Afrin was also cleaned this past year (a deeper evaluation of the Afrin operation and its aftermath can be found here and here).
