I think at this point the play is literally "cut our losses and run" much like Vietnam. We haven't even left entirely yet and the Taliban have made rapid advances and took over several state capitols with relative ease, which is only going to grow their strength even more. It's done, we lost and the only thing further intervention would accomplish would be prolonging the inevitable (the original invasion was also doomed to fail but no one could see that then). The US empire is looking a litte more shaky these days and with a growing rival in China, at some point we needed reduce our military commitments and recognize that the 20 year forever war has been a multi-trillion dollar sunk cost. The troops need to go occupy the south china sea now or some shit.

Especially with covid throwing the economy into danger, I think the US just wants out of the situation with as little consequences as possible. I think this whole thing about "we actually left Afghanistan strong and stable" is just going to be a way to blame the Afghans for losing while we try to claim :mission-accomplished:
