This weekend, President Trump publicly called off a secret meeting at Camp David with the Taliban and the president of Afghanistan that aimed to end the 18-year war, the longest in U.S. history. The United States and Taliban had appeared close to signing an agreement after holding nine rounds of talks in Doha, but the negotiations took a surprise turn when President Trump suggested a Camp David meeting that included Afghan President Ashraf Ghani, who had not been involved in the previous talks. For more, we go to Kabul to speak with Ali Latifi, a freelance journalist; Kathy Kelly, co-coordinator of Voices for Creative Nonviolence; and Dr. Hakim Young, a medical humanitarian worker. And in Washington, D.C., we speak with Matthew Hoh, a senior fellow with the Center for International Policy.
