Their fighters vanished into the mountainous rural areas, and their leadership fled to Pakistan. In retrospect, it is clear to me that this was a missed opportunity, a time when the US should have sat down with the Taliban to discuss a peace deal. I saw a genuine willingness amongst the rank-and-file of the Taliban to lay down their arms, and resume their lives. But the Americans didn’t want that. From my reporting, it seemed to me and many other Afghans that their motivation was revenge after 9/11.
