available in afghanistan, or they certainly haven't been used. there's that. but that has to be a key concern going forward. you know, i have to look at some of the evidence of what has happened on the ground here as well. the taliban have said that they wouldn't let afghans go through. their method of letting people get access to the airport has been hugely arbitrary and has contributed to the massive tail backs and the mess and the gathering of people. they have a huge level of responsibility here. they've come to power in this extraordinary way, essentially because they didn't tell the truth when they told us that they would negotiate with the afghan government. that's why that happened. they promised us that they will keep the united states and other countries safe by making sure that oal qaeda and other groups cannot use their territory. they said the same thing to russia, the same thing to china, that these groups cannot use their territory to attack beyond the borders, to attack the united states and others.
