and, frank wisner had a many-decades-long career in the foreign service. he was u.s.sador to india d to egypt, among other places, in the 1960s. he worked with the u.s. agency for international development in vietnam. he's currently a foreign affairs adviser to the law firm squire patton boggs. and we thank you all three for being back with us at the "newshour." robert grenier, let me start with you. as we mentioned, you were in southwest asia when 9/11 happened. you were there watching this unfold. looking back, did the u.s. make the right moves at that time? >> i think we did. we often talk about the u.s. invasion of afghanistan. in fact, it really wasn't an invasion at all. we only had a few hundred special forces operators and intelligence officers who were on the ground in afghanistan, very importantly, aided by u.s. close air support. but we came in very much with the idea that we needed to aid anti-taliban afghans to take charge of their own future. we departed from that model very seriously later on, but i think that we started out in the right way. >> woodruf
