At the conclusion of World War II, Gen. Henry H. “Hap” Arnold made a prediction: “We have just won a war with a lot of heroes flying around in planes. The next war may be fought by airplanes with no men in them at all. … It will be different from anything the world has ever seen.”
His timing wasn’t exact, but he was prescient. Drones, or unmanned aerial vehicles, weren’t used in the next war, but they have been deployed extensively in the global struggle against terrorism and extremist ideologies. And now we have to be careful they’re not used against U.S. interests by terrorists who modify civilian drones.
