NATO member Turkey turned to Russia to buy an advanced anti-aircraft missile system, a deal estimated to be worth $2.5 billion that has caused unease among its alliance partners. Turkish newspapers on Sept. 12 quoted President Recep Tayyip Erdogan as saying that Ankara has paid a deposit for the Russian S-400 air defense system. The purchase denies a major deal for Western contractors and will put in place a system that is not compatible with NATO air defenses. Russian media presented the deal, which would also provide Turkey with the technology to produce its own advanced air defenses, as a rebuke to Western governments.
The purchase comes at a time of growing strains between Washington and Ankara as Erdogan cracks down on political opponents and the United States sends arms to Kurdish militias in Syria that Turkey considers terrorists. Complicating matters, the deal may run afoul of U.S. sanctions against Russia. Politico reported on Sept. 14 that Sen. Ben Cardin (D-Md.) wrote to President Donald Trump that the deal would trigger mandatory U.S. sanctions against Turkey under legislation signed into law in August.—TERRY ATLAS
