What? How do you make that leap? The Taliban were infamous for this type of stuff well before 9/11 or OBL's capture.
Were they infamous for it before 1948?
Interesting, I've not heard that view before. Why wouldn't it have come to this?
IIRC the west intelligence community reported him as a sort of control on the taliban. How or why is a bit of a deep dive, but historically it looks like they were right.
