Do Non-Lethal Capabilities License to ‘Silence’?

Abstract

Most contemporary conflicts can be characterized as ‘wars or conflicts amongst the people’. International military forces deployed in such conflicts are confronted with complex operational environments where the distinction between combatants and non-combatants is often impossible to make. At the same time, there is a moral requirement imposed on Western coalition forces to perform in a humane manner and to keep casualties to a minimum. Non-lethal weapons are expected to enable military forces to accomplish their mission without having to kill or destroy. The extent to which these weapons meet that promise in real world conditions is the subject of debate. A defence technology assessment of non-lethal weapons is proposed that validates their utility and moral implications by considering the user, the weapon and the target in the context of the deployment situation. It will be illustrated that the technical parameters of the non-lethal weapons are no guarantee that the weapons will perform as intended as the user and target introduce many factors of uncertainty in real world situations. Although such uncertainties undermine the moral acceptability of non-lethal weapons, it is argued that the principle of non-lethality is compliant with the Just War Tradition principle of proportionality. The principles of non-combatant immunity and discrimination need to be re-calibrated given the human-centricity of many military intervention operations.
