Could human enhancement turn soldiers into weapons that violate international law?
New technologies reveal ambiguities and hidden assumptions in international humanitarian law.
Science fiction, or actual U.S. military project? Half a world away from the battlefield, a soldier controls his avatar-robot that does the actual fighting on the ground. Another one wears a sticky fabric that enables her to climb a wall like a gecko or spider would. Returning from a traumatic mission, a pilot takes a memory-erasing drug to help ward off post-traumatic stress disorder. Mimicking the physiology of dolphins and sled-dogs, a sailor is able to work his post all week without sleep and only a few meals.
All of these scenarios are real military projects currently in various stages of research. This is the frontlines of the Human Enhancement Revolution -- we now know enough about biology, neuroscience, computing, robotics, and materials to hack the human body, reshaping it in our own image. And defense-related applications are a major driver of science and technology research.
But, as I reported earlier, we also face serious ethical, legal, social, and operational issues in enhancing warfighters. Here, I want to drill down on what the laws of war say about military human enhancements, as we find that other technologies such as robotics and cyberweapons run into serious problems in this area as well.
Should enhancement technologies -- which typically do not directly interact with anyone other than the human subject -- be nevertheless subject to a weapons legal-review? That is, is there a sense in which enhancements could be considered as "weapons" and therefore under the authority of certain laws?
In international humanitarian law (IHL), also known as the laws of war, the primary instruments relevant to human enhancements include: Hague Conventions (1899 and 1907), Geneva Conventions (1949 and Additional Protocols I, II, and III), Biological and Toxin Weapons Convention (1972), Chemical Weapons Convention (1993), and other law. Below, I discuss these agreements and what their implications may be for human enhancement.
