Is Iran-Turkey rapprochement sustainable?

A high-level bureaucrat from the Turkish Ministry of Foreign Affairs told Al-Monitor, “The most important matter [between Iran and Turkey] is how to find a common ground in Syria. Turkey no longer calls for the ouster of [Syrian President Bashar] al-Assad. Yet, Tehran is not happy about our presence in northern Syria. Can Tehran play the role of broker between Ankara and Damascus? If Russia allows that, it may be possible. It will depend on how they approach the [Kurdistan Workers Party] PKK, which Turkey considers a terrorist organization and the same as other Kurdish groups in the region such as the YPG [People’s Protection Units].”
