is saying that this august 31st deadline depends on the taliban cooperating. you are saying they will not be able to do it by the 31st. today the taliban is saying no longer, they are no longer going to left afghans leave the country or reach the airport. does that mean the situation on the ground is already shifted? >> i think so. that, that's actually, you know, a very disturbing, to me, it's a breech in faith by the taliban, which is certainly, you know, consistent with their pattern. so, that's a very worrisome development, there's many other ways or other ways, covert are probably of spiriting people out or going out and getting them. that will get increasingly dicey and risky. both for the people that are attempting to rescue as well as the rescuers.
