The recent statement by Turkish President Erdogan that Ankara had made an advance payment to Russia for the purchase of two S-400 air defense batteries, combined with Russia’s confirmation of this report, constitutes a significant development that adds to the question marks about Turkey’s future in NATO. This development also strengthens Russia’s standing in the Middle East, because it is another expression of the rapprochement between Moscow and Ankara. However, the Turkish-Russian rapprochement does not by itself reduce the leverage available to the West in its relations with Turkey, above all the defense relations in the context of NATO and the extensive trade between Turkey and the European Union. While many believe that Turkey will remain a NATO member for the foreseeable future, they note at the same time that Turkey is a problematic member of the alliance that is already suffering from quite a few internal tensions.
