If anybody thought that Daesh's defeat would lead to de-escalation in Syria, they must be seriously disappointed..

President Recep Tayyip Erdoğan insists on U.S. troops withdrawing from Manbij, saying that promises President Barack Obama made to Ankara must be kept. His most recent threat to seek international legal action against Washington's support for the People's Protection Units (YPG) militia in northern Syria shows that Turkey's patience is running out.

Similar to the confusion prevalent among the U.S.'s traditional allies, Ankara is also experiencing some problems concerning the decision-making processes in U.S. politics.

As the number of dead YPG militants increases and Turkish-backed forces advance toward the center of Afrin, there will be a more determined effort to limit and ultimately render Operation Olive Branch unsuccessful

Astriking headline, "America Alone," on the cover of the latest issue of Time illuminated the sad state of U.S. foreign policy in the international system.

Claiming Turkey's Afrin operation harms the U.S. or NATO serve the interests only of countries like Russia and China

Washington needs to understand the legitimate reasons why Turkey launched its anti-terrorism operation against the YPG in northern Syria

Now it's Washington's turn to decide.

If Washington reconsiders its YPG policy, it will understand its irrational expectations of Ankara

Turkey's plan to build a wall on the Syrian border ruins the YPG's plans, and that is why it is trying to do its best to prevent the construction of the wall by killing workers

Operation Olive Branch is a more difficult operation in comparison to Operation Euphrates Shield because both Daesh and the YPG are terrorist organizations, but Daesh seemed to be a more legitimate target for the international community, whereas there is difference of opinion concerning the status of the PYD, even among Turkey's NATO allies

As a NATO ally, the U.S. shouldn't have underestimated Turkey's security concerns and instead, should have understood how serious Ankara is in dealing with YPG terrorists in northern Syria

Effective policy coordination and clarified functions are desperately needed from the democratically elected branches of the U.S. government, especially from Congress and the White House, but chances for improvement on those fronts are grim

The YPG is the Syrian arm of the outlawed PKK that has been fighting against the Turkish state for years, so it is impossible for Ankara to accept any presence of these militants near its borders

Ankara is getting ready for a military operation against the threat of a terror corridor on the Syrian border, dispatching military convoys to southern cities, hitting PKK/PYD targets in Afrin

Once again Daesh is being used as a stick to threaten the Turkish government
