The crisis in NATO and a complicated U.S. foreign policy are shaping Ankara-Washington relations, making it hard to predict the future

The NATO Council and Mediterranean Dialogue Partners Meeting took place in Ankara earlier this week, at a time when Turkey and the United States are experiencing tensions over the former's plan to purchase the S-400 missile defense system from Russia and disagreements on Turkish drilling in the Eastern Mediterranean.

The Donald Trump administration continues to use American power crudely every day. Washington not only continues to dismantle the post-World War II liberal order, an American creation, but has also imposed its unilateral national interest on the international arena and its actors.

The Trump administration is using sanctions, mostly economic sanctions, more aggressively compared to earlier administrations. Last summer, Washington imposed national security sanctions on Turkish steel and aluminum due to the detention of pastor Andrew Brunson in Turkey.

In a quest to assure stability in the region, Turkey has to find new, more active, regional partners and maintain its opposition against the unilateral policies of foreign players

'Mission accomplished' is such a catchy phrase that every executive in every field will be happy to use it to mark their achievement. It represents the successful execution and completion of a task: A solemn and proud pronouncement of victory and triumph.

The U.S. announced Monday it will not renew special waivers that allowed eight countries, including Turkey, to import Iranian oil without violating renewed sanctions.

The Trump administration continues to violate the basic principles of the international order established by the U.S. itself after World War II because the system no longer serves its interests. Rising global and regional powers, such as India, Indonesia and especially China, are the main beneficiaries of the continuation of the current system. The U.S. has been pursuing paradoxical policies, especially for the last decade.

Its geographic location as a bridge between East and West and its geopolitical significance made Turkey, particularly Istanbul, attractive for Bond movies. During the Cold War, as one of the most critical cities that absorbed the stress and tension of the rivalry between the Soviet Union and the U.S., the backdrop of Istanbul made the jobs of the producers of the popular culture films easier. This status of Istanbul continued following the end of the Cold War.

With no Daesh-held territories left and McGurk, Votel gone, time for the US to seriously reassess the role of CENTCOM and its policies

Earlier this week, senior Turkish officials visited the U.S. capital to prevent further deterioration of bilateral relations. Treasury and Finance Minister Berat Albayrak, Defense Minister Hulusi Akar, Trade Minister Ruhsar Pekcan and Presidential Spokesman Ibrahim Kalın shared Turkey's perspective with their counterparts.

As tension between Turkey and the U.S. regarding the S-400 air defense systems grows, the expectation is that a creative solution to de-escalate the stress on bilateral ties and find mutually acceptable ways out of this turbulence will be sought.

It is becoming more and more apparent that the relationship with the U.S. will dominate our foreign policy agenda in the upcoming years. This issue is not only limited to the widening rift in bilateral relations over the recent period but essentially related to the changing strategic calculations of Washington and Ankara.

Turkey's decision to purchase Russian S-400 air defense system has become a major sticking point with the U.S. While Turkey attaches great importance to procuring the air defense system, U.S. policymakers, who consider Turkey's decision a complete deviation from its traditional alliance system, have begun to threaten the country.

While many focus nowadays on the S-400/F-35 tensions taking place in Turkish-American relations, another issue, namely Syria, is being discussed at the highest levels among officials from the two countries. For the last eight years, the divergence of policies in regards to the crisis in Syria has become one of the most significant irritants in bilateral relations.

New developments fuel tensions between Washington and Ankara. Despite U.S. President Donald Trump's promises to President Recep Tayyip Erdoğan over the phone, no problem has yet gone away. Quite the contrary, the foreign policy establishment and Congress continue to try and undermine bilateral relations.

Turkish-American relations are strained again ahead of the delivery of S-400 air defense systems from Russia. In their Moscow meeting at the beginning of the week, President Recep Tayyip Erdoğan and Russian President Vladimir Putin confirmed the plan to deliver the first set of S-400 air defense systems to Turkey in early July.
