During the invasion of Iraq in 2003, the military conducted only a handful of drone missions. Today, the Pentagon deploys a fleet of 19,000 drones, relying on them for classified missions that once belonged exclusively to Special Forces units or covert operatives on the ground. American drones have been sent to spy on or kill targets in Iran, Iraq, Afghanistan, Pakistan, Yemen, Syria, Somalia and Libya. Drones routinely patrol the Mexican border, and they provided aerial surveillance over Osama bin Laden’s compound in Abbottabad, Pakistan. In his first three years, Obama has unleashed 268 covert drone strikes, five times the total George W. Bush ordered during his eight years in office. All told, drones have been used to kill more than 3,000 people designated as terrorists, including at least four U.S. citizens. In the process, according to human rights groups, they have also claimed the lives of more than 800 civilians. Obama’s drone program, in fact, amounts to the largest unmanned aerial offensive ever conducted in military history; never have so few killed so many by remote control.
