Turkey’s President Recep Tayyip Erdogan at long last met face to face with U.S President Joe Biden in the hopes of ironing out longstanding disagreements. Unfortunately for him, a limited meeting on the sidelines of a NATO summit was doomed to be limited in what it could achieve, said Aykan Erdemir, senior director of the Turkey Program at the Foundations for the Defense of Democracies (FDD) in Washington D.C. “The vast structural disagreements in U.S-Turkish relations are too vast to be solved on the sidelines of a NATO summit,” Erdemir told Ahval News in a recent podcast.
