Can We Trust Autonomous Weapons?

Nations consider using defense systems that can make their own lethal decisions. Most reasonable people can see the benefits of using fully autonomous systems, particularly to help prevent injuries or death, as is the case with advanced driver assistance systems increasingly found in automobiles. When it comes to autonomous systems that are designed to take life rather than preserve it, there is significantly more debate. Currently, the U.S. and other nations do not have any weapons systems that can operate fully autonomously, which is defined in military parlance as selecting, aiming, and firing at a target without a human being "in the loop," or somehow in control of the weapon system. However, a variety of military weapons systems operate semiautonomously, requiring some human control or input to select or choose targets, but relying on pre-programmed algorithms to execute a strike.
