General David H. Petraeus (US Army, Retired) and Vance Serchuk speak with ISW Founder and President Dr. Kimberly Kagan on the dangers of the US deal with the Taliban. They assess what the United States must do in Afghanistan to secure its national interests and prevent another 9/11. The US strategy in Afghanistan has been costly and unsatisfying - but also reasonably successful in preventing another terrorist attack on the homeland. The United States has made a peace deal with the Taliban in order to extricate its forces from Afghanistan, but it will soon lose the means to compel the Taliban to fulfill its part of the bargain. Should the United States pull its military out of Afghanistan anyway? Will the Taliban prevent international terrorists from returning? If so, can the United States counter terrorists in Afghanistan from afar?    General David Petraeus has served as Director of the CIA, Commander of Coalition Forces in Iraq and Afghanistan, and Commander of the US Central Command. He is now Chairman of the KKR Global Institute and a partner at KKR.  He also serves on the Board of Directors at the Institute for the Study of War. Vance Serchuk is the Executive Director of the KKR Global Institute and an adjunct senior fellow at the Center for a New American Security. He previously served as the Foreign Policy Adviser to Senator Joseph Lieberman.
