If the US had gone in the way the Brits, French, and I gather some other European nations did in the first hours and days of this mess, they would have been able to take advantage of the chaos and probably gotten a lot of Americans and even some translators out.
Not the Taliban has had time to organize, more to the point the various factions of the Taliban have arrived in town, and it is silly to think the guys sitting in the "Presidential Palace" actually control all the men on the ground.
Men who almost certainly are setting up checkpoints, demanding 2000 dollars in cash, beating Americans who don't/cacan't pay (banks have no money), and slitting the throats of translators.
Now the administration probably is either going to have to walk away and leave between 5 and 30 thousand Americans to their fate or dive right back in with troops, the very thing "Biden" said he had avoided.
