"Persistent media attention tends not to differentiate between armed and commercial drones, but rather homogenizes all types, despite the fact that armed drones will be more destabilizing. Though the armed drones acquired by states in the near term likely will not have capabilities equal to those of the United States, their effects will still be destabilizing. States that acquire armed drones will likely use them as probes and for limited attacks in international waters and across borders, against domestic threats, and, potentially, for even more lethal missions, including delivering weapons of mass destruction (WMDs). Although other vehicles, such as trucks and manned civilian aircraft, can also be used to deliver WMDs, the ability of drones to hover and wait for the opportune moment in which they can produce maximum effect confers uniquely lethal capabilities."
