Russian President Vladimir Putin greets Turkish counterpart Recep Tayyip Erdoğan, Moscow, January 24, 2019 (AP)

In light of Turkey’s purchase of S-400 anti-aircraft missile systems from Russia, defying the US and risking sanctions, I chatted with Voice of Islam Radio for 25 minutes on Tuesday to evaluate the changing relationships.

While noting the significance of the S-400 deal, I suggested that it is rash to say Turkey is breaking with Washington and NATO.

We discuss the possibilities through a look at the region and far beyond, from China to Iran to Europe, and at the personal politics of Turkish President Recep Tayyip Erdoğan.
