In his book Ender's Game, Orson Scott Card envisioned a not-so-distant future where intergalactic war is waged and won by child soldiers. It doesn't take a genius to see the parallels between this, and the US military's move towards UAVs and combat robots that are controlled by soldiers who are hundreds or thousands of miles away from the battlefront -- and there's no reason why the US military couldn't use children to control these weapons of death.
