President Recep Tayyip Erdoğan is in Washington, D.C. today for a highly anticipated meeting with U.S. President Donald Trump. There are many issues on the two leaders' agenda, including Turkey's procurement of the Russian S-400 air defense system, Washington's relationship with the PKK terrorist organization's Syrian branch and the fight against the Gülenist Terror Group (FETÖ).

French President Emmanuel Macron told The Economist last week that NATO was "brain dead." He blamed the alliance's supposed problem on the lack of "coordination... of strategic decision-making between the United States and its NATO allies." Macron added that Turkey's actions were "uncoordinated," warning that NATO failed to monitor the actions of its members.

President Recep Tayyip Erdoğan on Thursday announced his decision to visit Washington. He reached that decision following a phone call with U.S. President Donald Trump, who invited him.

Turkish-American relations are experiencing the heavy burden of Washington's alliance with the People's Protection Units (YPG), as the YPG is the Syrian branch of the PKK terrorist group, which Turkey has been struggling against for the last four decades. This vision will not change any time soon despite Washington's denial of the PKK-YPG connection. There are many other significant obstacles to the normalization of Turkish-American relations but Washington's flirt with the YPG is the most controversial one.

Turkey initiated a large-scale Westernization project immediately after the declaration of the Republic. It had decided to follow the footsteps of the enemy it had fought during World War I and the Independence War. It introduced many political, economic, even social and cultural reforms during the first two decades of the interwar period. In the wake of World War II, the Soviet threat further paved the way for Turkey's alliance with the West.

Last week, anti-Turkey activism in Washington reached new heights. For the last one month, the campaign against Turkey deteriorated the ties between the two countries at the public level. In addition to setting a tone against Turkey in the U.S., it also generated a serious reaction from the Turkish public against the U.S.

The death of the Daesh leader is a significant development in the fight against the terror network. The literature on terror organizations argues that for terror groups utilizing religious discourse and religious framing for collective mobilization, the decapitation, death or imprisonment of leaders is a highly effective intervention.

Much has been written regarding Ankara's negotiations with Russia and the U.S. and the process and potential outcomes of the accords the countries have reached following intense diplomatic activity.

In the last seven decades, since the beginning of the strategic relations between Turkey and the U.S., there have been different tensions and crises between the two countries. Observers and historians of Turkish-American relations have defined some of these crises as "turning points" and "critical junctures" that significantly affected the general trajectory of bilateral ties.
