In the 1970s and 1980s, it was commonly assumed that terrorist use of weapons of mass destruction (WMD) would be counterproductive because such an act would be widely condemned. “Terrorists want a lot of people watching, not a lot of people dead,” Brian Jenkins (1975:15) opined. Jenkins's premise was based on the assumption that terrorist behavior is normative, and that if they exceeded certain constraints and employed WMD they would completely alienate themselves from the public and possibly provoke swift and harsh retaliation. This assumption does seem to apply to certain secular terrorist groups (Alexander, 1981). If a separatist organization such as the Provisional Irish Republic Army (PIRA) or the Basque Fatherland and Liberty (Euzkadi Ta Askatasuna—ETA), for example, were to use WMD, these groups would likely isolate their constituency and undermine sources of funding and political support.
When the assumptions about terrorist groups not using WMD were made in the 1970s and 1980s, most of the terrorist groups making headlines were groups with political or nationalist-separatist agenda. Those groups, with some exceptions, such as the Japanese Red Army (JRA—Rengo Sekigun), had reason not to sabotage their ethnic bases of popular support or other domestic or foreign sympathizers of their cause by using WMD. Trends in terrorism over the past three decades, however, have contradicted the conventional thinking that terrorists are averse to using WMD (Amos, 1985). It has become increasingly evident that the assumption does not apply to religious terrorist groups or millenarian cults (see Glossary). Indeed, since at least the early 1970s analysts, including (somewhat contradictorily) Jenkins, have predicted that the first groups to employ a weapon of mass destruction would be religious sects with a millenarian, messianic, or apocalyptic mindset.
When the conventional terrorist groups and individuals of the early 1970s are compared with terrorists of the early 1990s, a trend can be seen: the emergence of religious fundamentalist and new religious groups espousing the rhetoric of mass-destruction terrorism. In the 1990s, groups motivated by religious imperatives, such as Aum Shinrikyo, Hizballah, and al-Qaida, have grown and proliferated. These groups have a different attitude toward violence—one that is extranormative and seeks to maximize violence against the perceived enemy, essentially anyone who is not a fundamentalist Muslim or an Aum Shinrikyo member. Their outlook is one that divides the world simplistically into “them” and “us.” With its sarin attack on the Tokyo subway system on March 20, 1995, the doomsday cult ...
