He remained, under arms, in Afghanistan after his co-jihadists carried out 9-11. He was there in the military service of a regime at war with the USA, because that regime was sheltering the perpetrators of 9-11.
Had I found Sulayman, I would have just shrugged and told the nearest Northern Alliance guy that Sulayman appeared to be yet another Pakistani or Saudi, and let them dispatch him however they saw fit.
Do you think he really knew that? I mean come on. He was THERE, do you really think he was THERE to do the US harm. I dont think so.
He was in the wrong place at the wrong time. Do you really think that he wanted to kill Americans? I just dont buy it. I was studying Afghanistan and the taliban long before 9/11. The majorities of the people are just scrapping by and love their religion. That doesnt make them dispatchable.
