Torture creates enemies and radicalizes people
Among the most notable victims of torture was Sayeed Qutb, the founding father of modern political jihadism. His 1964 book, “Milestones,” describes a journey towards radicalization that included rape and torture, sometimes with dogs, in an Egyptian prison. He left jail burning with the determination to wage transnational jihad to destroy these regimes and their backers, calling for war against all those who used these methods against Muslims
“Milestones” remains one of the Arab world’s most influential books. Indeed, it was the lodestar of Al Qaeda leaders like Ayman Al-Zawahiri (who was also tortured in Egyptian jails) and the late Osama Bin Laden.
In other words, it was torture which drove the founder of modern jihad to terrorism in the first place.
The article goes on to list a variety of other, very important people, radicalized by torture.
I mean, if I were thrown in prison, tortured and raped, and got out, you can damn well bet when I got out I’d want the order that did that to me destroyed.
I will note also that drone warfare/assassination warfare does the same thing. It is very rare that assassination programs do anything but bring more radical leaders to the fore. The only prominent exception I can think of is the probable assassination of Arafat.
