There are multiple problems to the rest of the world 'sorting out' Afghanistan.
Thr Taliban is a cult. They didn't reason themselves into their views, so can't be reasoned out of them.
Their astounding brutality means the chances of internal.rebel-group suppprt for external intervention are small.
They aren't susceptible to international political pressure, because they simply don't care what we think of them (see 'cult' above).
Economic and cultural sanctions are ineffective against a country with little international trade to damage. By contrast, South Africa had a lot of goods to sell, and a rich, internationalist political class who wanted to buy foreign goods and consume wider culture. They cared that they couldn't sell their fruit or have global pop stars tour. The Taliban don't want any part of the decadent west, and have little to sell but opium (whch they disapprove of, so it's not exactly a government-level trade). But we should still have refused to play their cricket team. Just because the effect is minimal doesn't mean we shouldn't bother.
Which leaves military intervention. And that's never worked against Afghanistan. Not now, not in the 19th century (if you're not familiar with the First and Second Anglo-Afghan wars, have a read). A modern military force does not do well against dedicated and well-armed guerrillas, with no military legal code, operating in inaccessible terrain (see also Vietnam). And if we do manage to invade, we're back to the problem that got us here in the first place - if the West holds Afghanistan, Russia undermines us; if Russia holds it, we undermine them. Whoever has it is not only fighting the Afghans (see, again, right back to the First Anglo-Afghan war). And these days Pakistan, India and China would probably also get involved.
That doesn't leave a lot of options.
One thing we could do is a simple, automatic asylum process for any woman who gets out. And ensure they get further than Pakistan. I'm not sure how much can be done to assist them to the border, but the second they set foot across they should be protected. We can lobby our government, and they can lobby the governments of the surrounding countries, for that.
