In his new book "The Fifth Act: America's End in Afghanistan," combat veteran and acclaimed novelist Elliot Ackerman documents the horrors of America's evacuation from Afghanistan. He talks with Brian Stelter about why he wrote the book; what people need to know about the August 2021 withdrawal; and the media's coverage of war. In "our obsession not to repeat Saigon... we actually created, I think, a far more terrible image and grisly image," he says. Ackerman also shares how the war in Ukraine relates to last year's images from Kabul. He predicts that "America might be done with Afghanistan, Afghanistan is certainly not done with America."To learn more about how CNN protects listener privacy, visit cnn.com/privacyLearn more about your ad choices.
