Firstly, without question civilians are dying, not lots but to pretend no civilians are involved is stupid, and what muslims there are killing what civilians? I'm fairly sure muslims in Afghanistan aren't killing civilians over there, they are fighting our military, they are a defensive force, we're invading.
We're at the point where some completely and utterly innocent kid, from a farming family whose parents were killing earlier in this "war" was led to hate us because his family was killed as a result of us being there, so has joined up with their forces to fight us. That kids still innocent, he's doing nothing more in his eyes, than our lads did in the world wars to fight off Germany. We're an invading occupying force with no end game, no plan and realistically no reason. We're doing nothing more than breeding hate for us in the population of their country and other countries also. We're increasing the hatred for us and that will lead to a higher number of true fanatics who will commit terrorist actions against us and feel fully justified in doing so.
We aren't fighting the terrorist cells that blew up planes on 9/11, or tried to a few days ago, we're fighting largely innocent people who are angry or misled, the real criminals behind the real terrorist attacks are off hiding, probably completely safe planning more attacks, while we simply provide them with more fanatic followers.
