I'm not saying it was a good thing, I'm saying it's what the rest of the world wanted the US to do. After all the accusations of imperialism and global hegemony &etc., the US military finally packed up and left, even though this outcome with the Taliban was fully predictable.

So now what, the US should go back and fix it? Occupy Afghanistan again?

We gave them a whole fucking army?

In this case, pretty much. The Taliban do not negotiate and do not honor agreements made in negotiations. Oh, they'll happily sit down at a table with you and tell you anything you want to hear, and accept any concessions you want to give them, but they won't do what they've said. After the US pulled out and the Taliban took over they super promised that they wouldn't oppress women again:

Zabihullah Mujahid, the Taliban’s longtime spokesman, emerged from the shadows Tuesday in his first-ever public appearance to address those concerns at a news conference.

He promised the Taliban would honor women’s rights within the norms of Islamic law, without elaborating.

And of course, we know what they've actually done:

the Taliban have issued more than eighty edicts targeting the twenty million women and girls who make up just short of 50 percent of Afghanistan’s population. Women and girls face draconian restrictions in public life, namely, on education, employment, access to the justice system, and activities and travel outside the home.

The Taliban traffic women as slaves, just as they did when they were in power before. They are not going to be convinced to suddenly start respecting women according to western ideals about equality through any sort of political pressure. If you want to stop the Taliban's oppression of women, the only option is to remove them from power.
