If you care about them so much, maybe you should bend your efforts to reducing their moral culpability and think about the strategic logic of the entire mission, which has now killed 10 times more Afghan civilians than died on 9/11, in a country with 1/10 the population of ours, so as to lower the probability of their being selected as a target.
How much longer is the US going to continue trying to win hearts and minds by throwing the most highly equipped military force on the planet at lightly armed peasants, while ignoring the fact that they probably feel just as pissed off about their friends, family, and selves being blown up as we do about ours, and by now have suffered far more than the original injury we are still attempting to retaliate for?
There are now kids old enough to sign up for the military who were born after 9/11 and for whom the US has always been at war with Afghanistan, and your moral gymnastics serve only to perpetuate that while foreclosing any inquiry they might conduct as citizens rather than soldiers.
