The wars in Ukraine and Iran have made clear that the nature of warfare is changing, with drones reshaping the battlefield. But the idea of weapons systems with no people onboard is not a new one. At the end of  World War II, Gen. Henry “Hap” Arnold, commanding general of U.S. Army Air Forces, said, “The next war may be fought by airplanes with no men in them at all.” It took some time, but the U.S. military has at least partially achieved Arnold’s vision.
