How about, "a comparison of the number of Afghani children who have been killed by the Taliban and Al-Queda"(you can include those used as human shields), "to the number killed by U.S. and NATO forces," would be the basis for some meaningful discussion.
I still do not believe that the deaths of children by U.S. and NATO forces are unintentional when war is an intentional act. There is no moral high ground when children die as the result of the actions of adults. To claim some kind of moral high ground is to deny any responsibility.
Its creepy to think that some people think they are not accountable for their actions. Who do you think you are? Is this because God chose you to carry out his wicked will? Listen carefully. I think you may be confusing God for Satan.
