Since the late 20th century, the legal status of targeted killing has become a subject of contention within and between various nations. Historically, at least since the mid-eighteenth century, Western thinking has generally considered the use of assassination as a tool of statecraft to be illegal.[5] Some academics, military personnel and officials[6] describe targeted killing as legitimate within the context of self-defense, when employed against terrorists or combatants engaged in asymmetrical warfare. They argue that unmanned combat aerial vehicles (drones) are more humane and more accurate than manned vehicles.[7][8]
