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).

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.

Another important meeting in Washington between President Recep Tayyip Erdoğan and U.S. President Donald Trump is expected to be held next week. The state of Turkish-American relations and the crises between the countries make this meeting more critical than any other to date between the two leaders.

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.

The five days of intense diplomacy are here. The first step to determine northern Syria's fate was taken in Ankara, where Turkish President Recep Tayyip Erdoğan hosted U.S. Vice President Mike Pence. By Tuesday evening, a second step must be taken. In his meeting with Russian President Vladimir Putin, Erdoğan will complete the proposed safe zone's main framework.

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.
