In April 2016, a search for “drone warfare” on Google returned almost 550,000 results, while Amazon.com listed 205 book titles. The proliferation of scholarly and popular writings on the topic directly reflects the explosive growth of unmanned aerial vehicles (UAVs) over the last two decades. And there is much more to come, as we are still very much in the midst of the military robotics revolution. Some defense analysts go so far as to argue that Predator, the first and most famous high-tech, remotely operated UAV in the United States (US) armada, “may someday be to drone warfare what the V-2 was to long-range ballistic missiles: a crude, but important, first step in a new era of warfare” (Weinberger, 2014).
