Roughly two weeks ago, ISIS captured the ancient Syrian town of Palmyra, sparking concerns that the violent extremist group would destroy the antiquities there. What is the significance of Palmyra? Although the ruins evidently remain intact so far, are fears of its destruction by ISIS nonetheless warranted? And how does the political-military operation there fit into ISIS's broader plans for the region? Dr. Andy Terrill joined Dr. John R. Deni to discuss these questions and more. Released 5 June 2015.
