we're talking about american citizens, american green card holders, afghan nationals who have helped us, fought alongside our soldiers. they lost over 60,000 soldiers in the 20-year conflict. we've lossed 2500 soldiers in the conflict. as you point out we have american military members right there on the ground right now heroes going to try to save these lives of americans and afghan allies all in harm's way. they are congregating at the gates where they are being let into the airport. thousands of people at various gates around the airport. i don't want to describe which gates people are at. but i will say this. there are taliban checkpoints all around the airport that you have to proceed through just to get to the gates that they are being advised to go to. at times they're being told draw back from the gates, step back. they are told if you want to get out of the country before withdrawal happens you have to go to the gates. there is a tension.
