S-400 missile system

Turkish Foreign Minister Mevlut Cavusoglu has discussed by telephone with US Secretary of State Mike Pompeo the Russian S-400 missile defence system and the U.S. F-35 fighter jet program, a foreign ministry source said on Saturday.
The source did not say when the conversation took place.

Turkish Foreign Minister Mevlüt Çavuşoğlu and his U.S. counterpart Mike Pompeo had a phone conversation on July 20, in which they discussed the F-35 fighter jet program and S-400 air defense systems issues and
Syria, according to Turkish diplomatic sources.

The US decision to exclude Turkey from an American-led fighter jet program goes against the "spirit of alliance," the Turkish government said Thursday, and called on its NATO ally to reverse the decision.

As Russia starts delivering its S-400 missile systems to Turkey, experts say Ankara's widening rift with the West and NATO can only benefit the strategic interests of the Kremlin.

The United States said on Wednesday that it was removing Turkey from the F-35 fighter jet program, a move that had been long threatened and expected after Ankara began accepting delivery of an advanced Russian missile defense system last week.

President Donald Trump said on July 16 the U.S. will not sell Turkey advanced F-35 fighter jets over Ankara's acquisition of the Russian S-400 anti-air system, bemoaning the fact and blaming his predecessor for the impasse.     

US President Donald Trump said on Tuesday it is "not fair" to either Turkey or the United States that Washington cannot sell Ankara billions of dollars worth of F-35 fighter jets after it bought a Russian air defense system.

President Donald Trump on Tuesday signaled reluctance to punish Turkey over its acquisition of a Russian air defense system, saying it was "not fair" that the United States would now be prohibited from selling Ankara billions of dollars worth of F-35 stealth fighter jets.

US President Donald Trump's nominee to become the next secretary of defense re-stated that Turkey cannot have the F-35 advanced stealth fighter jet and Russia's S-400 air defense system, which Moscow started delivering last week.
