"America and the Taliban" examines the 20-year war in Afghanistan

It was August 2021 when the U.S. closed the door on its 20-year war in Afghanistan with a scattershot exit from the country as the Taliban took over. A new three-part documentary from PBS’s Frontline looks at the war from all angles and examines how things went so wrong. The first episode was released this week, with the other two coming later in April. Martin Smith is a long-time Frontline correspondent who covered the war in Afghanistan and is one of the producers of “America and the Taliban.” We talked with Smith about the documentary and the mistakes that were made over two decades in Afghanistan.
