the concern there. i want to show what you anthony blinken said this morning. >> president biden is intent on avoiding a saigon moment. that is the humiliating exit from vietnam. with the troop surge, are not we already in the midst of a saigon moment? >> no. we're not. remember, this is not saigon. we went to afghanistan 20 years a ago with one mission. that was to attack the people who attacked us on 9/11. >> even the images are evocative of what happened in vietnam. >> let's take a step back. this is manifestly not saigon. >> but look at these pictures. on the left you see the famous picture of the helicopter fleeing the sim in saigon. on the right. another helicopter, another u.s. embassy but that's this morning in kabul.
