They are still being evacuated from the country mostly by former American military personnel.
First, not by former American military personnel. An ex-Marine would have no idea how to payoff a Taliban customs official, or buy fuel from a black market dealer. More importantly, the last place you want to be caught is next to former American military. It makes you look like CIA agent, and you will be executed. The Taliban is not that upset with people leaving, but working with the CIA is a big deal.
If you want to get out of Afghanistan, you pay a bribe to the local warlord/crime boss. They will gladly get you out. The Taliban does not want to have to deal with people who do not want to be there.
The Biden administration isn't doing it.
If America tries to help you in Afghanistan, you will be executed. No one wants that type of help. They want help getting out, but not getting out through death.
You have watched too many Rambo-style movies. That is not the way to get out of this situation.
We also have thousands of legal permanent residents trapped in Afghanistan.
Many chose to stay there. They had businesses or family they did not want to abandon. They thought, rightly or wrongly, they could work with the Taliban.
Zablon Simintov was believed to be the last Jewish person in Afghanistan. His family had been in Afghanistan since before Jesus. He refused to leave, even after the Taliban took over, because he did not want to get a divorce from his wife(who was in Israel). The Taliban wanted him out, but did not want to push him out. Finally, they agreed to pay a whole bunch of his neighbors to leave with him. There was no need to hire Rambo.
