To facilitate a detailed analysis of the various dimensions of terrorism, it would be helpful to do a general threat assessment of terrorism and to discuss the leading global problems both today and in the future that may affect terrorism. Terrorism is currently a lethal, destructive phenomenon with the potential to cause massive casualties. Advances in counter-measures, however, have not progressed at the same pace. Concerns about cyberterrorism and terrorist access to Weapons of Mass Destruction (WMD) are increasing. Accordingly, this paper will examine four key subjects: cyberterrorism, WMD, the media, and legal dimensions of terrorism.
