Ok radical. I served 9 years in the military and no one I worked with was evil. Service members honestly believed they were doing good in the world and many felt some of the wars they were forced to participate in were unjust. Life is way more nuanced.

Generally, it was the intended targets of those drones who decided to hide among children. Meaning, usually, in areas with children nearby.

The rate at which children are harmed by drones is largely a consequence of strategies outside of American control once you posit that the targets are targeted justly.

I am not saying that stupid mistakes and civilian death don't happen.
