The relations between Turkey and the U.S. have recently undergone a sudden and unexpected deterioration. With the election of Trump, there was an expectation on the Turkish side that there would be some amelioration in the relations, because during President Obama's last term, there were contradictions due to differences in opinion between Turkey and the U.S. on issues such as on FETO and YPG. However, as the problems emerge, such as Trump's policy of arming the YPG more and more, not taking any steps regarding the FETO issue, the relations are at an impasse. Moreover, the arrest of Turkish citizens who worked in some of the U.S. Official Agencies within that period, some unfair pressures on Turkish citizens in the United States, imprisonment of Pastor Brunson, with the US discomfort on S400 subject the Turkey's rapprochement with countries like Russia and Iran being in search of new alternatives, left even deeper traces in the relationship. Just before 2018, visa suspension led to a trust issue, as it was not even the case during the crisis with Russia.
