Robo-Wars: The Regulation of Robotic Weapons by Alex Leveringhaus and Gilles Giac (2014).
This policy paper summarises different types of military robots and outlines the relevant technological features of robotic weapons. It provides an overview of the ongoing debates as to whether the use of robotic weapons is legal and ethical. It then assesses current proposals for the regulation of robotic weapons. Finally, the paper makes recommendations to states, manufacturers and the military on how to develop a suitable regulatory framework for robotic weapons.
This article describes the new strategic discourse of network-centric warfare that has come to dominate US operational doctrines and concepts as well as strategic thinking. It also describes 11th September as a network attack. The state of exception becomes the rule via the confluence of geopolitical with biopolitical power and the strategic logic of network-centric thinking, and with it the problematization of security goes hyperbolic in the form of `The Terror'.
