THE SPREAD OF MILITARY DRONE TECHNOLOGY: “This does not constitute an arms race, at least not in usual ‘competitive driver’ sense of the term. Countries are acquiring drones not because other countries are acquiring them, but because they are concluding that irrespective of how other countries behave, drones are a cheaper, more efficient, more useful alternative to manned aircraft. There is an independent incentive to acquire drones that is independent of any competitive strategic pressures; countries would do this in any case.”
