9/11 changed international relations and U.S. foreign policy. In this video, Ed Husain, Senior Fellow for Middle Eastern Studies at the Council on Foreign Relations, who was previously a member and strategist for radical Islamist organizations in London discusses the impact of the Sept. 11, 2001 terrorist attacks on Islamist extremism as well as global counter-terrorism efforts. "The most important thing that happened after 9/11," says Husain, "is not just the so-called 'War on Terror', but more importantly, the unspoken and often unheard developments within Islamist extremism globally."
