the decision to elevate the taliban and do a deal with them during the trump administration. was that a mistake? were they given too much control for them to be saying anything is a red line? should america be listening to the taliban? >> you know, they are a notable enemy. they have done extremely well and you have to respect your enemy. that's one of the fundamental principles of being a military person. you've got to talk to your enemy. it took a long, long time. we had opportunities earlier to do that, we didn't take them. finally the window opened and we had the opportunity to sit down and talk with them and start hashing out an agreement. so this is how these wars have to end. insurgencies are just horrifying. they're devastating. and the human cost and the emotional cost, but you've got to start talking sometime. >> i got you with the talk. but bringing them to camp david, elevating them that way, allowing them to dictate terms and then to continue honoring an agreement even after they didn't, was that a mistake?
