Iran is clearly the lesser evil here and in an ideal scenario they're gonna occupy Afghanistan, reopen education for girls which then (unintentionally) paves the way for women rebelling against theocratic authority like they did in Iran.
Which also proves that the Taliban have a point, I guess, from their perspective. From a pro-human rights perspective however there's something to be said for a (slightly) looser grip creating an opening for dissent.
The Taliban have no point. Not allowing women to receive an education or be treated equally leads to resentment among all women, including Pashtuns. People and women in Iran are rebelling because the boot on their neck isn’t worth it and the regime’s messaging and promises since 2013-4 has been out of wack.
There's clearly a linkage between Iranian women's level of education and the (relative) success of the Woman, Life, Freedom movement in the country, in particular since the leaders of the movement tend to be more educated women. On the other hand, you can't exactly write protest signs with the words "Woman, Life, Freedom" on it when you can't, well, write.
While there may be resentment among Afghan women (again, particularly the more educated ones who had held prominent positions in Afghan society prior to 2021) you won't have any resentment any longer if you succeed in raising a generation which doesn't even know what they should be resented about exactly, because they lack the necessary knowledge to draw such a conclusion in the first place.
It shouldn't be underestimated that, up to certain point, sheer brutality works. When German colonial authorities exterminated all the Herero in present-day Namibia there wasn't any resentment among Herero anymore because there simply weren't that many Herero around anymore. And last year I went to Prague. The fact that barring one exception all the synagogues in the old Jewish quarter have been converted into museums is a testament to the long-term "effectiveness" of Nazi tactics. That should serve as a warning. Totalitarianism works, it it isn't stopped.
