I just found this transcript of a PBS “Nightline” episode. It says that Taliban madrassas teach first, reading, and second, the Koran.
If it’s true, and they can
read, of course that doesn’t mean they do read.
Interestingly, the transcript also says that this type of extremist education is almost entirely underwritten by our good friends the Saudis.https://www.pbs.org/wgbh/pages/frontline/shows/saudi/analyses/madrassas.html
The reason I look this stuff up is that generalist statements, particularly about an enemy or someone treated as an enemy, raises some doubt in me, and an interest to know more.
