Although researchers know a great deal about persuasive messages that encourage terrorism, they know far less about persuasive messages that denounce terrorism and little about how these two sides come together. We propose a conceptualization that distinguishes a message’s support for an act from its support for the ideology underlying an act. Our prediction is tested using corpus-linguistic analysis of 250 counter-extremist messages written by Muslims and U.K. officials and a comparison set of 250 Muslim extremist messages. Consistent with our prediction, Muslim extremist and Muslim counter-messages show disagreement on terrorist actions but agreement in ideological aspects, while U.K. officials’ counter-messages show disagreement with both Muslim extremists’ acts and ideology. Our findings suggest that counter-messages should not be viewed as a homogenous group and that being against violent extremism does not necessarily equate to having positive perceptions of Western values.

Popular opinion expresses fear that accessing radical Islamic content and connecting with extremist networks through Internet functionalities causes radicalization and recruitment to commit terrorist acts. Anecdotal evidence has been used to support this assertion. The opinion assumes the Internet creates a new path that drives radicalization and recruitment. Whether computer-mediated communication (CMC) and Internet functionalities cause individuals to radicalize has not been thoroughly studied. This thesis explores whether a correlation can be found to attribute radicalization to radicalizing content and extremist networks accessed through CMC and Internet functionalities. A framework is used to evaluate vulnerabilities identified by the psychological, sociological and social-psychological elements of radicalization against the radicalization process, personal history, and the presence of radicalizing conventional communication and extremist contact. The analysis finds three cases that may support a conclusion that Internet radicalization is possible; however, the importance of root causes and individual vulnerabilities may have a greater impact. Since some circumstances involving CMC may increase the likelihood of radicalization, the fear of Internet radicalization may be reasonable, but the number of incidents validating that fear makes the threat unlikely and appears more like a phantom menace than a real threat.

What causes an individual to take up violence against civilians for the sake of a political, religious, or social goal? Of course, there are many possible answers to this question. But, one view suggests that narratives may play an especially important role in changing the beliefs, attitudes, and intentions that are precursors to terrorism. There are at least three important implications of this position. First, it is necessary to determine what is meant by terrorism and related terms. Establishing the conceptual boundaries of these terms is a prerequisite to understanding the relationships among them and with narrative communication. Second, it must be established empirically that narrative has the persuasive potency that has been attributed to it. Although narrative has been compared to other forms of evidence, the impact of narrative communication (vs. none) on beliefs, attitudes, intentions, or behavior, has not been determined. Finally, it is important to directly assess the content of narratives that are intended to radicalize. A close examination of the content within terrorist narratives is needed to reveal the targets of belief and attitude change. By determining the persuasive efficacy of narratives and exploring the radicalizing potential of a specific set of extremist narratives, this project advances our knowledge of narrative persuasion processes and helps address the problem of terrorism by approaching it from a communication-based perspective. Chapters 1 and 2 are dedicated to the explication of key terms. Chapter 1 explores the notions of terrorism and extremism, two contested concepts within the literature. Terrorism is defined as the use of violence or threat of violence against civilians to achieve ideological goals. Extremism is defined as a psychological state in which an individual rigidly adheres to an ideology that is characterized by behaviors that marginalize other-minded individuals through a variety of means, up and including the use of physical violence. A model is proposed that suggests that extremism is a risk factor for engaging in terrorism. As Chapter 1 explored the psychological origins of terrorism, Chapter 2 investigates the psychological origins of extremism. This chapter argues that extremism results from a process referred to as radicalization. Radicalization is defined as an incremental social and psychological process prompted by and inextricably bound in communication, whereby an individual develops increased commitment to an extremist ideology resulting in the full or partial assimilation of beliefs and attitudes consistent with that ideology. Thus, it is proposed that those who undergo radicalization are at risk for extremism, and in turn, at risk for engaging in terrorism. After demonstrating radicalization to be a contributing factor for engaging in terrorism in Chapter 2, Chapter 3 illustrates the efficacy of one source with which radicalization can be promoted, narratives. In Chapter 3, meta-analytic techniques are employed to demonstrate that narrative communication positively affects beliefs (N = 4,510; r = .20), attitudes (N = 5,861; r = .21), and behavioral intentions (N = 4,218; r = .19), suggesting that extremist narratives have the potential to contribute to fundamental changes in beliefs, attitudes, and intentions in the direction of those promoted by a terrorist group. Given these results, a close examination of a terrorist group’s narratives would illustrate the beliefs, attitudes, and intentions that might be affected by exposure to those narratives. Thus, Chapter 4 features a theme analysis of the narratives of a terrorist organization, The Animal Liberation Front (ALF). This analysis reveals 10 distinct content themes that are geared towards radicalization. Taken together, the findings of Chapter 3’s meta-analysis and Chapter 4’s theme analysis show how the ALF’s narratives work to promote extremism. Chapter 5 summarizes the findings from the previous chapters and discusses the implications of them. Specifically, this chapter briefly details the ways in which this dissertation may inform future research on narrative communication and strategies to mitigate the impact of extremist narratives on the radicalization process.

Attacks on computer systems for both criminal and political purposes are on the rise in both the United States and around the world. Foreign terrorist organizations are also developing information technology skills to advance their goals. Looking at the convergence of these two phenomena, many prominent security experts in both government and private industry have rung an alarm bell regarding the potential for acts of cyber-terrorism. However, there is no precise definition of cyber-terrorism under United States law or in practice among cyber-security academicians. The lack of a common starting point is one of the reasons existing law fails to directly address cyberterrorism. This paper furnishes a lexicon of cyber-related malicious activities and argues for a common working definition of cyber-terrorism. This definition can be both incorporated into current counter-terror legislation and used by government agencies to combat cyberterrorism. This paper arrives at that definition by analyzing the various definitions proposed by security experts and those in use by governmental organizations. This paper builds on these definitions to arrive at a new definition that is at once broad enough to cover the potentially unique effects of a weapon of cyber-terrorism, while narrow enough to exclude computer network attacks that are relatively minor in nature. Second, analyzing several recent cyber attacks, this paper finds that, while we have not yet faced a “cyber 9/11,” computer network attacks for political purposes are on the rise and becoming increasing complex. Third, this paper analyzes current law related to both cyber-crimes and terrorism, finding that while these laws are applicable in many instances, they fall short in adequately focusing on the most important factor when addressing cyber-terrorism: prevention. This paper concludes by recommending that cyber-terrorism, as defined in this paper, be incorporated into some of our most frequently used laws to combat terrorism.

The US electricity infrastructure uses Industrial Control Systems (ICS) to oversee its operations. These systems are connected online for better efficiency, making them susceptible to cyberattacks. Current research has extensively addressed ICS vulnerabilities that can be exploited by cybercriminals. Vulnerabilities, however, are only one of the many factors influencing offender decision-making in cyberattacks. Furthermore, numerous conceptions of threats, vulnerabilities, and consequences exist, which further complicate ICS security assessments. This exploratory study therefore has two main goals. First, it seeks to compare industry and hacker perceptions on electricity ICS threats, vulnerabilities, and consequences. Second, it seeks to identify a broader set of factors that influence offender decision-making in ICS cyberattacks.

This study is focused on three topics regarding Geneva Convention III. First, is the process of classifying conflicts either as a Common Article 2 or Common Article 3 armed conflict at the onset of hostilities. Conflict classification is critical to the implementation of the Geneva Conventions in warfare and carries with it vast implications dependent upon that decision. The criterion for this classification is presented and, by using the United States as a case study, evaluated to determine whether this aspect of the conventions remains not only applicable but adequate to states who are a party to the treaty. Determinations of the United States and the legal support backing these decisions are thus investigated.
