Cyber and Drone Attacks May Change Warfare More Than the Machine Gun

From state-sponsored cyber attacks to autonomous robotic weapons, twenty-first century war is increasingly disembodied. Our wars are being fought in the ether and by machines. And yet our ethics of war are stuck in the pre-digital age.

We're used to thinking of war as a physical phenomenon, as an outbreak of destructive violence that takes place in the physical world. Bullets fly, bombs explode, tanks roll, people collapse. Despite the tremendous changes in the technology of warfare, it remained a contest of human bodies. But as the drone wars have shown, that's no longer true, at least for one side of the battle. Technological asymmetry has always been a feature of warfare, but no nation has ever been able to prosecute a war without any physical risk to its citizens. What might the ability to launch casualty-free wars do to the political barriers that stand between peace and conflict? In today's democracies politicians are obligated to explain, at regular intervals, why a military action requires the blood of a nation's young people. Wars waged by machines might not encounter much skepticism in the public sphere.
