U.S. Secretary of State Mike Pompeo said on July 30 the United States was continuing to evaluate how it would respond to Turkey's purchase of Russian S-400 missile defense systems.
"We continue to evaluate how to apply sanctions in order to achieve our end objective," Pompeo said under questioning from Democratic Senator Bob Menendez at a Senate Foreign Relations Committee hearing.
Turkey’s decision to acquire the Russian-made S-400 surface-to-air missile systems has caused a sharply negative reaction from the United States and NATO as a whole. The United States insists that Turkey must give up the Russian air defense systems.Turkey 'tested Russia’s S-400 air defense systems on US-made planes last year'
As Turkey has said that it will not give up the S-400 systems, Washington has excluded Ankara from the US program of developing the fifth-generation F-35 fighter-bomber.
The United States is also threatening Turkey with unilateral sanctions over the purchase of S-400 air defense systems.
