"U.S.-allied Afghan soldiers fired directly into the truck, killing many of them"

If this happened, then it is probably because those Taliban fighters were hated by the Afghani soldiers for reasons that are not in the film.

We should have killed more Talibans - the Afghanis haven't finished the job.

They should show the films about the way it was in Afghanistan before the Taliban and Al Quada were retaliated against after 9/11.
