In 2009, not long after his historic election and seven years after the first U.S. drone strike, President Barack Obama accepted the Nobel Peace Prize. Since then, however, deadly U.S. drone strikes have increased sharply, as have doubts about the programs reliability and effectiveness. The latest criticism comes from Drone, a new documentary about the CIAs covert drone war. To help promote the film and inveigh against the agencys drone program ... four former operators - Stephen Lewis, Michael Haas, Cian Westmoreland and Brandon Bryant - appeared at a press conference. Speaking out can lead to veiled threats and prosecution. Which is why for years Bryant was the only drone veteran who openly rebuked the drone war. But his persistence and his appearance in the film, the other three say, inspired them to come forward. On multiple occasions, the men say they complained to their superiors about their concerns to no avail. Drone strikes kill far more civilians than the government admits. These deaths, they argue, wind up helping militant groups recruit new members and hurt the U.S.s long-term security. By distancing soldiers from the battlefield, the operators suggest the people carrying out strikes may become even more desensitized to killing than their counterparts on the front lines. On some occasions, Haas says operators referred to children as fun-sized terrorists or TITS, terrorists in training.
