GAYLE TZEMACH LEMMON.

MARTHA RADDATZ (ABC NEWS) (Off-camera) For more now on US troop withdrawal, let's bring in someone who has spent 15 years reporting on Afghanistan, especially the plight of women there. Gayle Tzemach Lemmon, adjunct senior fellow at the Council on Foreign Relations, and author of "The Dressmaker of Khair Khana." Good to see you, Gayle. I have heard general after general, as you have, say, just give us a little more time. Politicians say it, as well. And yet, you cannot call this a successful effort given what's going on with the Taliban. So, when you look at it, why isn't Biden right just pulling out those troops? [ABSTRACT FROM PUBLISHER]
