Why has ISIS been so difficult for the United States and it’s allies to defeat? Hassan Hassan, co-author of the New York Times best seller, “ISIS: Inside the Army of Terror” joins us to discuss both the challenges that have been faced in conquering ISIS, as well as the effects that President Trump’s new defense policies in the Middle East will have on stopping the global ISIS threat.

In addition, to being one of the most knowledgeable experts on the history and inner workings of ISIS, Hassan has worked with the Brooking Institute, Carnegie Endowment for International Peace, European Council on Foreign Relations, and the Tahrir Institute for Middle East Policy in Washington DC. He has testified before the Senate Homeland Security and Government Affairs Committee and also the House Foreign Affairs Committee on defeating terrorism in Syria.
