Brilliant Iranian interviewer Kaveh Taghvai's questions on the subject are inspired in this debate - more of a discussion - between J. Michael Springmann, a former US diplomat, and Michael Lane, the founder of American Institute for Foreign Policy, both from Washington. The two guests and the interviewer all have an unusually deep grasp of the drivers of turmoil in the region and of the foreign players involved. We get some very interesting new perspectives and interpretations of the latest moves around Syria. For instance, Turkey's position is often hard to fathom. We know it wants to take land from the north of Syria, whilst pretending to be maintaining safe zones. We know it wants to drive the Kurds back, but the usefulness of the refugee camps for Turkey as a military buffer may not have occurred to everyone.
