Amanpour: Adm. William McRaven (Ret.), Elizabeth Becker and Michio Kaku

Three U.S. presidents have tried and failed to end the war in Afghanistan, and President Biden says he refuses to be the fourth. By September, he will withdraw thousands of U.S. troops from the country and NATO is likely to follow.
