The Dawning of an Ethical Dilemma: Armed Drones in Warfare


Drones are now a staple of the US military’s war effort in Iraq and Afghanistan. Elsewhere the Chinese and Israeli militaries (among others) are increasing their Unmanned Arial Vehicle (UAV) arsenal. Indeed arsenal is the correct term to employ. Typically consigned to surveillance and radio jamming missions, these once infertile vehicles, now carry lethal payloads of advanced missiles and weaponry. While this increased capacity may seem like the natural technological evolution, many ethical scholars are concerned with this development.

Consider the case for armed drones when it is phrased as such “automated machine for slaughtering 3rd world occupants”.[1] This argument suggests that the prosperity of the west allows the waging of an extremely low risk, low casualty war against a people incapable of offering the slightest resistance to such devices. Is this not merely slaughter rather than ‘war’?

The cost of war is typically measured by the casually count incurred. Kunz notes that “Taking away the human element reduces incentive to avoid war”.[2] As technology advances, and UAVs become the norm, rather than the exception, can we expect a more passé public reaction to conflict situations? Perhaps it is already happening, the anti-war lobby at the unfolding of the Iraq and Afghanistan wars have been muted in recent years. This is likely in response to the minimal number of US casualties experienced due to the employ of around 7,000 UAVs in the two war-zones. The number of causalities speaks volumes about the impact of UAVs on mortality rates; The US casualties for the Iraq war are 4353, while Iraqi deaths are estimated at around 1.4 million.[3]

Perhaps the darkest aspect to the ethical debate is the issue of artificial intelligence error. Writing in the Journal of Applied Philosophy, Robert Sparrow asks “who we should hold responsible when an autonomous weapon system is involved in an atrocity of the sort that would normally be described as a war crime.” Indeed it is difficult to assess who is an innocent, or who is a enemy from thousands of feet above ground. This is brought home whenever one hears news stories of wedding parties been obliterated because the military mistook the large gathering of people for a terrorist gathering.

These ethical concerns seem to be disregarded by governments and militaries. Militaries appreciate the low-casualty benefit of these devices and are developing them further. This week China unveiled its own natively produced UAV.[4] And, ambitiously, the United States Army’s Future Combat Systems Project has undertaken the task to manufacture a ‘robot army’ for deployment by 2012.[5] These developments sit uncomfortably when it appears that there is, generally, very little effort to understanding the ethical implications of these aircraft. One hopes that these concerns will be brought to the forefront of political debate by informed and capable bodies.
