Could the mere threat of using an armed drone ever coerce an enemy to change their behavior ‚Äď without attacking them?
Yes, says Stanford political scientist¬†Amy Zegart, who argues in a new¬†research paper¬†that countries that simply possess deadly, armed drones could change an adversary‚Äôs behavior without even striking them. Zegart is the Davies Family Senior Fellow at the¬†Hoover Institution¬†and co-director of Stanford‚Äôs¬†Center for International Security and Cooperation.
‚ÄúArmed drones are likely to offer coercion ‚Äėwindows of opportunity‚Äô in at least one important circumstance: states that have armed drones confronting states that do not,‚ÄĚ she said. ‚ÄúAs wars grow longer and less conclusive, armed drones enable states to sustain combat operations, making threats to ‚Äėstay the course‚Äô more believable.‚ÄĚ
Zegart believes that drone technology is becoming a more effective instrument to change a state‚Äôs behavior than yesteryear‚Äôs more costly option of using ground troops or large-scale military movements in war or conflict.
‚ÄúDrones may be turning deterrence theory on its head,‚ÄĚ said Zegart, referring to the cost-benefit calculation a potential aggressor makes when assessing an attack.
Zegart‚Äôs focus is on¬†next-generation drones, which are essentially unmanned fighter jets and¬†are currently¬†in development. She is not examining the use of existing drones like quadcopters and Reaper and Predator unmanned aerial vehicles.
Foreign military officers surveyed
Zegart‚Äôs research is based on surveys of 259 foreign military officers conducted between 2015 and 2017. Participants were highly experienced foreign military officers who were attending classes at the National Defense University and Naval War College.
A drone is an unmanned aircraft that can be piloted remotely to deliver a lethal payload to a specific target.
Today, Zegart said, many scholars are studying whether drone proliferation across the world could change the future of warfare.
‚ÄúBut even here the focus has been the implications for the¬†use¬†of force, not the¬†threat¬†of force,‚ÄĚ she said.
New drones are more lethal than ever, offering greater speeds, ranges, stealth and agility, according to Zegart. The U.S. is ahead, but not alone, in using drones. Nine countries have already used armed drones in combat, and at least 20 more are developing lethal drone programs ‚Äď including Russia and China.
‚ÄúIt is time for a rethink‚ÄĚ about drones, Zegart said. Technological advances will soon enable drones to function in hostile environments better than ever before.
‚ÄúDrones offer three unique coercion advantages that theorists did not foresee: sustainability in long duration conflicts; certainty of precision punishment, which can change the psychology of adversaries; and changes in the relative costs of war,‚ÄĚ she said.
Threats involving a high cost may be actually less credible than assumed, said Zegart. Her findings challenge the belief of ‚Äúcost signals,‚ÄĚ a military strategy where a country threatens another with a high-cost option, such as ground troops, which is intended to show resolve.
Drones may actually signal a nation‚Äôs resolve more effectively because ‚Äď as a low-cost option ‚Äď they can be part of an enduring offensive campaign against an enemy.
‚ÄúThe advent of armed drones suggests that costly signals may no longer be the best or only path to threat credibility,‚ÄĚ she said. As wars grow longer and less conclusive, a particular country‚Äôs test of resolve becomes ‚Äúmore about sustaining than initiating action.‚ÄĚ
‚ÄúIn situations where a coercing state has armed drones but a target state does not, drones make it possible to implement threats in ways that impose vanishingly low costs on the coercer but disproportionately high costs on the target,‚ÄĚ Zegart said.
Zegart said that throughout history, whenever a new military technology emerges, adversaries have basically faced two choices ‚Äď either concede or innovate to overcome the other side‚Äôs advantage.
‚ÄúThere is no reason to expect drones will be any different. The more that drones are used for combat and coercion, the more likely it will be that others will develop drone countermeasures,‚ÄĚ she said.
New weapons often evolve technologically before ‚Äúgame-changing ideas‚ÄĚ occur about how to use them, Zegart added. This was true of submarines before World War I, tanks after World War I, airplanes (which originally replaced surveillance balloons and were not used to drop bombs until 1911), and nuclear weapons during the Cold War.
‚ÄúWhile physicists in the Manhattan Project developed the first atom bomb in just three years, it took much longer to develop the conceptual underpinnings of deterrence that kept the Cold War cold,‚ÄĚ she said.
Drones raise important questions about the role of machines in decision-making during conflict, Zegart said. For example, much has been debated and written about the ethical and legal issues raised by U.S. drone strikes, the usefulness of drone operations against terrorist groups and whether the Pentagon or CIA should control and operate the drones.
Such questions are likely to grow more ‚Äúnumerous and knotty‚ÄĚ as drones and other technologies evolve, she said.
