In September 2002 the President of the United States issued a new National Security Strategy. Under the impact of 9/11 the authors of this NSS argue that the United States needs to pre-emptively attack rogue states that try to develop weapons of mass destruction (WMD) and have links to terrorists who might use these WMDs against the United States or its allies.
