The United States has offered to sell its NATO ally Turkey a $3.5 billion Patriot missile defense system as an incentive for the country not to buy an anti-aircraft missile system from Russia, according to Turkish state media.
Turkey’s defense and foreign affairs ministries are discussing the purchase of U.S. Patriot missiles with officials from a U.S. delegation, according to the reports.
Turkey had planned to purchase an S-400 anti-aircraft missile system from Russia despite warnings from the U.S. and other NATO allies that the system could pose security risks if integrated with Western systems. Turkey signed a deal with Russia in 2017 that was reportedly worth $2.5 billion.
