we will do everything we can to make sure that is the case. >> everything except use the u.s. military. president biden is intent on avoiding a saigon moment, a reference of course to the hasty and humiliating u.s. evacuation from vietnam. but with this troop surge to air lift americans out of afghanistan, aren't we already in the midst of a saigon moment? >> no we're not. remember, this is not saigon. we went to afghanistan 20 years ago with one mission. and that mission was to deal with the folks who attacked us on 9/11. we have succeeded in that mission. the objective we set bringing those who attacked us to justice, making sure they couldn't attack us again from afghanistan, we've succeeded in that mission. in fact we succeeded a while ago. at the same time, remaining in afghanistan for another one, five, ten years is not in the national interest.
