This dissertation investigates how different stakeholders have competed over the interpretation and commemoration of the Aum Affair. The Aum Affair was a series of crimes committed by new religious movement Aum Shinrikyō between 1988 and 1995, which culminated in the gassing of the Tokyo subway system using sarin in March 1995. The Tokyo attack was the largest act of terrorism in post-war Japan. I combine qualitative methods of media analysis, interviews, and participant observation to analyse how different stakeholders have narrated and commemorated the Aum Affair. I propose ‘collective trauma’ as a revised theory of ‘cultural trauma’ to describe an event which is represented as harmful and indelible to collective memory and identity. In contrast to ‘cultural trauma’, which stresses the importance of symbolic representations of traumatic events, ‘collective trauma’ considers other ‘material’ processes – such as establishing facts, collective action, state responses, and litigation – which also contribute to trauma construction. My overarching argument is that various stakeholders – including state authorities, mass media, public intellectuals, victims, and former Aum believers – have constructed the Aum Affair as a collective trauma in multiple and conflicting ways. Many media representations situated Aum as an evil ‘cult’ which ‘brainwashed’ believers and intended to take over Japan through terror. State authorities also responded by treating Aum as a dangerous terrorist group. In some instances, these binary representations of Japan locked in a struggle against an evil force led to municipal governments violating the civil rights of Aum believers. Some individuals such as public intellectuals and former believers have challenged this divisive view by treating Aum as a ‘religion’, not a ‘cult’, and locating the root causes of Aum’s growth in Japanese society. Additionally, victims and former members have pursued divergent goals such as retributive justice, financial reparations, and social reconciliation through their public actions. A key conclusion of this dissertation is that whilst confronting horrific acts of violence may require social construction of collective trauma using cultural codes of good and evil, the entrenchment of these symbolic categories can result in lasting social tension and division.

Although Japan is not a state which would often be associated with terrorist attacks, several extremist and terrorist groups formed in the country in the second half of the 20th century. One of them was the ultraleft terrorist organization called Japanese Red Army, which was founded in the 1960s as a part of the student leftist movement, and the second was Aum Shinrikyo, a religious millenarian organization founded in the economically prosperous 1980s as one of the so-called new new religious groups. Both these groups, circumstances of their establishment and the way they chose targets of their terrorist attacks are the studied subjects of this work. The first part of this study focuses on the theoretical description of terrorism. In the following chapters, I focus on both groups, specifically on two selected terrorist attacks, in which I examine the influence of the following factors on the choice of their targets: ideology, quality of leadership, quantity and quality of members, weapons available and financial base. Concerning the Japanese Red Army, the thesis focuses on the terrorist attack on the Lod airport (1972) and the attack on the U.S. and Swedish Embassy in Kuala Lumpur (1975), regarding Aum Shinrikyo, it is the attack on the Sakamoto family (1989) and the Tokyo subway sarin attack...

The rise of the 21st Century Islamic extremist movement, which was mobilised by the al-Qaeda attacks of and responses to September 11, 2001, heralds a new period in the history of terrorism. The increased frequency and intensity of this type of terrorism affects every nation in the world, not least Australia. Rising to meet the challenges posed by terrorism is the field of terrorism studies, the field which aims at understanding, explaining, and countering terrorism. Despite the importance of the field, it has been beleaguered with criticisms since its inception as a response to the rise of international terrorism. These criticisms specifically aim at the field's lack of objectivity, abstraction, levels of research, and levels of analysis. These criticisms were the impetus behind the adoption of the methodology of this thesis, which offers the distinct ability to understand, explain, and forecast the way in which terrorists interact within covert cells. Through social network analysis, this thesis examines four terrorist cells that have operated in or against Australia. These cells are from the groups Hrvatsko Revolucionarno Bratstvo (Croatian Revolutionary Brotherhood), Aum Shinrikyo (Supreme Truth), Lashkar-e-Taiba (Army of the Pure), and Jemaah Islamiyah (Islamic Community) and operated between 1963 and 2003. Essentially, this methodology attempts to discover, map, and analyse the interaction within the cells during the covert stage of their respective operations. Following this, the results are analysed through the traditional social network analysis frameworks to discover the internal dynamics of the cell and identify the critical nodes (leaders) within the cells. Destabilisation techniques are subsequently employed, targeting these critical nodes to establish the most effective disruption techniques from a counter-terrorism point of view. The major findings of this thesis are: (1) that cells with a focus on efficiency rather than covertness were more successful in completing their objectives (contrary to popular belief); and (2) betweenness centrality (control over the flow of communication) is a critical factor in identifying leaders within terrorist cells. The analysis also offered significant insight into how a Jemaah Islamiyah cell might operate effectively in Australia, as well as the importance of local contacts to terrorist operations and the significance of international counter-terrorism cooperation and coordination.
