Another perspective-how Obama created the current dillemma:
"...By now, the negotiations that would lead to the Iran nuclear deal were underway. But Damascus was the close ally of both Russia and Iran, so any American intervention in Syria risked upsetting the new relationship that Obama was attempting to forge with Moscow and Tehran.
This factor is the hidden key to understanding why Team Obama gravitated to the YPG to solve its problems. The group had a long history of cordial relations with the Russians and the Iranians, and, best of all, it had no intention to topple the Assad regime. Every other group that Obama might have used to defeat ISIS had an anti-Assad agenda.
So, no, Trump is not betraying the YPG. He is seeking to restore balance to American foreign policy.
The YPG knew from the beginning that its relationship with Washington was temporary and transactional. It didn’t fight as a favor to the United States. America armed, trained, equipped and funded the YPG. We gave it strong military support, including aerial bombardment, which allowed it to vanquish all foes in its neighborhood. Thanks to this assistance, the power, influence and territorial reach of the group expanded beyond its wildest dreams. In the meantime, America also held Turkey at bay.
The YPG benefitted enormously from the effort, and the Turkish-American relationship suffered in equal measure...."
