Really? How would you know that? We were giving Massoud suitcases full of cash, Stingers and all the weaponry we could launder through Pakistan. OBL was not at the top of his list of concerns. He was never interested in fighting in the south, which is why we got hooked up with Karzai in the first place - trying to find a halfway credible opposition force in the south. The Northern Alliance had next-to-nothing to do with Kandahar Province, and knew that - as non-Pashtuns - they stuck out like sore thumbs down there and had no support.
The problem with 'its just a movie' is that you've got hordes of folks, particularly here, running around saying "it is ALL true." Like the dumbasses who really think we should've launched a bunch of cruise missles over Pakistan without telling them, at a time when they were in a nuclear standoff with India.
