After a decade of gradual rapprochement anchored by booming bilateral energy ties and close coordination on combating Kurdish separatists, Iran and Turkey are struggling to maintain a veneer of mutual amity and cooperation.
In recent months, Iran and Turkey have shown growing signs of estrangement. At the heart of their differences lie the Syrian crisis and Ankara’s gradual alignment with the West’s efforts to check Iran’s nuclear ambitions. The two neighbors continue to be bound, however, by a complex and deepening state of energy interdependence, which explains why both sides continue to exercise a measure of self-restraint in their engagements with one another.
A rapidly evolving Kurdish dynamic in northern Syria has also presented a dilemma for Iran and Turkey, which are both deeply concerned with the prospect of Kurdish aspirations for sovereignty.
