Sinan Ülgen is a visiting scholar at Carnegie Europe in Brussels, where his research focuses on Turkish foreign policy, nuclear policy, cyberpolicy, and trans-Atlantic relations. Ülgen was in Beirut in mid-December for the annual conference organized by the Carnegie Middle East Center. Diwan caught up with him on the margins of the conference to discuss the fraught relations between the United States and Turkey, Turkey’s future in the Middle East, and what Ankara would consider an acceptable endgame in Syria.
