Terrorist groups have evolved substantially in the two decades since 9/11. While the understanding of terrorism has grown immensely over the past two decades, similar advancements in the understanding of counterterrorism lag. In the Routledge Handbook of U.S. Counterterrorism and Irregular Warfare Operations, a range of contributors place the focus of analytic attention on U.S. counterterrorism efforts and how it has adapted alongside the changes in terrorist activity. In honor of the memory of Ambassador for Counterterrorism Michael Sheehan, who edited the volume, New America has convened a discussion of these topics.

To discuss the changes in counterterrorism and terrorism over the past two decades, New America and the Center on National Security at Fordham Law School welcome four contributors to the volume: Peter Bergen, Liam Collins, Luke Hartig, and Elisabeth Kendall. Peter Bergen is Vice President at New America. Col. (ret.) Liam Collins is Executive Director of the Viola Foundation, a fellow with New America’s International Security Program, former director of the Combating Terrorism Center at West Point, and founding director of the Modern War Institute at West Point. Luke Hartig is a fellow with New America’s International Security program, previously served as Senior Director for Counterterrorism at the National Security Council, and is president of National Journal Research. Elisabeth Kendall is Research Fellow in Arabic & Islam at Oxford University (Pembroke). She is also the chairman of a grass-roots NGO in Yemen and former director of a UK-government sponsored centre aimed at developing Arabic-based research expertise. The discussion will be moderated by Karen J. Greenberg. Greenberg is the Director of the Center for National Security at Fordham Law, a fellow with New America’s International Security program, and author of Subtle Tools: The Dismantling of American Democracy from the War on Terror to Donald Trump.
