Osama Bin Laden chose Afganistan because he thought he could win there, he thinks he did the winning against the USSR and the US doesn't have the advantage of short supply lines.
Doesn't matter we have to root out the Al Queida no matter how remote they are , as long as their intent is to attack Americans we make ourselves safer by killing them.
I understand that a lot of Afgans do not even know what this fight is about , they do not know what happened on 9-11-2001 and don't know why we are angry, when they are told that we are trying to stamp out Islam they beleive it. As far as this we need Psy ops a lot more than we need bullets. Note the Talib quoted at the head of this thread , does he even know that Americas gates were already attacked? Has he any idea that Osama Bin Laden invited us to this party?
