After months of deliberations, Turkey began to take delivery of the Russian S-400 missile defense system last week.

The Foundation for Political, Economic and Social Research (SETA) last week published a report on international media outlets and their operations in Turkey.

The ups and downs in Turkey-U.S. relations in the last two decades have generated a paradoxical situation for scholars and observers alike.

Ankara's confrontation with Washington on the delivery of the Russian-made S-400 air defense system has been one of Turkey's top foreign policy issues in the last several months.

Pesident Recep Tayyip Erdoğan's bilateral meeting with U.S. President Donald Trump in Osaka, Japan marked a new chapter in the S-400 dispute. A textbook example of leader-to-leader diplomacy, that meeting paved the way for Trump lending support to the Turkish position on Patriot missiles, the Russian air defense system and the F-35 jet fighter program.

The leader-to-leader diplomacy between the U.S. and Turkey at the G20 summit was crucial in defusing the S-400 dispute and turned it into a potential communication tool for bilateral ties

Since the beginning of Trump's presidency, the two leaders have pretty regularly communicated with each other in face-to-face meetings or through phone calls. This has been an important factor in determining bilateral ties in the last two-and-a-half years.

World leaders gathered in Osaka this week for the G20 summit. The summit will witness important side meetings between different heads of states on matters related to critical areas. One of those critical meetings will take place between President Recep Tayyip Erdoğan and U.S. President Donald Trump. Given the looming crisis in the relations between the two countries, various unresolved issues in bilateral relations will be discussed in this meeting.

S-400s are not technical problem but political one, says expert

A few weeks ago, this column detailed how, in the last two decades, U.S. administrations have periodically made war plans and debated conflict scenarios. Both the George W. Bush and Barack Obama administrations did it, and now the Donald Trump administration has come to a similar point of deliberating a military response against Iran.

Pentagon officials continue to maintain the same dysfunctional and hostile policies against Turkey. They are now using Turkey's purchase of the S-400 air defense systems from Russia as a pretext to pressure and threaten Turkey. The Pentagon's recently resigned chief Patrick Shanahan had warned his Turkish counterpart Hulusi Akar about economic sanctions and the abandonment of military cooperation between the two NATO allies.

With the S-400 missile defense system's delivery around the corner, tensions are escalating between Turkey and the United States. The Turks are committed to buying the Russian system despite Washington's threats. The Pentagon's most recent letter to Defense Minister Hulusi Akar, which included a long list of threats, did not change Ankara's mind either.

Relations between the U.S. and Turkey have hit a critical juncture. I don't know how many times it has been written in the last few years that relations are now at a critical point, but today that statement has never been truer.

The United States took its first 'concrete step' to encourage Turkey to rethink its plan to purchase the S-400 missile defense system from Russia. Washington was going to exclude Turkish pilots from the F-35 fighter jet training program, Reuters reported last week.

Turkey has a very busy agenda ahead of itself for the month of June..

Nowadays, it has become commonplace among foreign policy scholars to debate the future of Turkish-American relations.
