More recently, however, Turkey became far less static and much more complex and unpredictable than many American observers and policymakers appreciate. Turkish foreign policy—in particular toward the Middle East—has endured a broad, historic shift during Prime Minister Erdoðan’s decade-long tenure. This fundamental reorientation of Turkey’s worldview has been difficult to detect, because it has been overshadowed by rapid policy swerves that, on the surface, seem hard to reconcile within a unitary framework. But it is precisely this volatility, combined with Turkey’s importance for the Middle East, that makes understanding the roots of Turkish conduct vital, not only for a realistic U.S. approach toward Turkey but also for U.S. policy toward the entire region.
