If you thought all United States Air Force drone pilots are pleased with what they’re accomplishing — remotely dropping bombs on the extremist cauldron that is Syria, Iraq, Afghanistan, etc. — then you’d be gravely mistaken.

Because a handful of former drone pilots recently came forward with their displeasure, voicing their verbal protest with the U.S. government’s program through a British newspaper no stranger to controversial issues against American foreign and domestic policy (they were first to break the Snowden revelation back in May of 2013).

This from The Verge:

Four former US Air Force drone pilots have come forward with a blistering critique of the current drone program, first published in The Guardian. In an open letter addressed to President Obama, Secretary of Defense Ashton Carter, and CIA director John Brennan, the pilots argue the civilian casualties and resulting devastation from US drone strikes have radicalized regions where it is used, fueling the rise of ISIS and other terrorist organizations.

“This administration and its predecessors have built a drone program that is one of the most devastating driving forces for terrorism and destabilization around the world,” the letter reads.

According to the four pilots, the damage from the drone program’s isn’t limited to America’s reputation. All four pilots report suffering from post-traumatic stress disorder, and say subsequent medical care and benefits have been inadequate. The letter also references gross mismanagement of the program, citing Chelsea Manning and Edward Snowden as examples that compelled them to speak out. “Silence would violate the very oaths we took to support and defend the Constitution,” the pilots write.

Unfortunately for these former virtual aviators, the program doesn’t seem to be going anywhere. In recent polls, the majority of Americans support it, just like all major candidates in the upcoming presidential race deem it an effective and vital technique of counterterrorism — including, of course, Hillary Clinton, who voiced her approval of drones while secretary of state.
