The number of innocent victims of drone strikes remains "extremely small" and doesn't outweigh the benefits of using drones to take out al Qaeda operatives, former Defense Secretary Robert Gates argued Sunday.
But the former Pentagon chief said a better system of checks and balances could be constructive when the unmanned aerial devices are used to target Americans, aligning himself with lawmakers concerned about unfettered power in the hands of the president.
Gates served under George W. Bush during the beginnings of the drone program and later under President Barack Obama as the use of drones spiked. Recently lawmakers, both Democrats and Republicans, have forcefully questioned the use and oversight of the lethal devices.
