Dexter Filkins covered the American invasion of Afghanistan when he was a reporter for the New York Times, and has continued to report on conflicts in the region for The New Yorker. Filkins’s best-seller from 2008 carried the resonant title “The Forever War.” Thirteen years after the book’s publication, the forever war is over, but its end has been the chaotic worst-case scenario that many feared. Filkins talks with David Remnick about whether it had to go this way, and whether twenty years of war changed America more than it did Afghanistan. Plus, The New Yorker’s puzzles editor puts David Remnick and Naomi Fry through a couple of rounds of the new online quiz, Name Drop.
