The Strength of Weak Terrorist Ties

The current age of technology, mass communication, and globalization makes networks analysis an especially useful tool for understanding cell-based terrorism. Some concepts from traditional networks analysis may be especially relevant. The Strength of Weak Ties hypothesis (SWT) is particularly promising and will be used here to demonstrate the usability of traditional networks analysis for studying modern terrorism. The findings suggest that the strength of weak terrorist ties may improve Al Qaeda's operational capabilities despite the group's decentralization following the U.S.-led military campaign in Afghanistan beginning in 2001.     

Choose Your Weapon: The Impact of Strategic Considerations and Resource Constraints on Terrorist Group Weapon Selection

ABSTRACT

Historians of terrorism note that modern terrorists rely almost exclusively on two weapon types: the gun and the bomb. However, the comparative use of these weapons differs from one terrorist group to the next. We exploit this variation to examine how the tactical decisions of terrorists respond to both strategic aspirations and resource constraints. We argue that a group’s goals (a strategic consideration) and size (a resource constraint) provide a parsimonious explanation for weapon selection. Because firearms inherently expose the shooter to higher risk, are more precise, and must be used if a group aspires to maintain social order, they are unlikely to be used by groups with limited recruits in a campaign of violence. We test this theory using data on over 350 terrorist organizations. Our analysis shows that strategic considerations and resource constraints both impact tactical choices, although groups with the most expansive goals, those which transcend national borders, as well as militias, are two interesting exceptions to our theory. Our research has implications for the use of disaggregated tactical data and in furthering our understanding of the rationality of terrorism.     

Terrorist Incidents in India, 1998–2004: A Quantitative Analysis of Fatality Rates

Using data from the University of Maryland's Global Terrorism Database II, this paper first provides information on the nature of terrorist incidents in India in the period 1998-2004: the Indian states that were worst affected by terrorist incidents and fatalities; the terrorist groups responsible for such incidents and their modus operandi. Next, the paper focuses on the issue of fatalities from terrorist incidents. It inquires into the extent to which the number of fatalities following an incident was influenced by the type of attack (bombings, armed assault, etc.) and the extent to which it was influenced by the type of terrorist group. By examining the number of fatalities resulting from terrorist attacks in India, the paper disentangles the influence on this number of attack type and attack group. Lastly, the paper applies Atkinson's concept of equality-adjusted income to terrorism to arrive at the concept of equality-adjusted deaths from terrorist incidents: in order to avoid spectacular incidents resulting in the loss of a large number of lives—as in New York on September 11, 2001 and in Mumbai 26–29 November 2008—“society” might be prepared to tolerate “low-grade” terrorism which resulted in a larger number of deaths in total but avoided a large number of deaths from a single iconic incident.     

Deadlier in the U.S.? On Lone Wolves,Terrorist Groups,and Attack Lethality

Scholars, politicians, and pundits increasingly suggest lone wolf terrorists are substantial threats, but we know little about how dangerous these actors are—especially relative to other terrorist actors. How deadly are lone actor terrorists? A growing body of empirical research focuses on terrorist organizations, but similar work on lone actors is sparse. Furthermore, attempts to explicitly compare these or other types of terrorist actors are almost non-existent. This article considers theoretical arguments for why lone wolves ought to be especially lethal. However, it presents an argument for why terrorist groups should generally be more lethal. This argument is conditional upon the environment in which actors operate. Lone wolves should only be more deadly in states with especially strong counterterrorism capacity. The article uses data on terrorist attacks in fifteen developed countries, 1970–2010, to compare the lethality of terrorist acts. Around the world, attacks by organizations tend to be far more lethal than attacks by other actors. In the United States, however, lone wolves are generally the more lethal terrorist actors. This is argued to be because the robust counterterrorism capacity makes organized terrorism more difficult to accomplish.     

The Economic Cost of March 11: Measuring the Direct Economic Cost of the Terrorist Attack on March 11, 2004 in Madrid

This article attempts to measure the direct costs that the terrorist attacks of 3/11 had on the economy of the region of Madrid. The evaluation has been made applying conservative criteria, and the results obtained have to be considered as minimum. The result indicates that the terrorist attacks caused a loss of nearly 212 million euros to the regional economy of Madrid, equivalent to 0.16 percent of the regional GDP (0.03 of the national GDP). This confirms that the immediate economic dimension of a terrorist attack such as the one of 3/11—apart from human catastrophic consequences—is relatively low.     

Competing to Kill: Terrorist Organizations Versus Lone Wolf Terrorists

Are organizationally linked suicide attacks deadlier than those launched by lone wolf terrorists? This article elaborates a perpetrator-based distinction among suicide terrorist attacks between organizations and lone wolf terrorists, who operate in the absence of a financially or physically supportive terrorist organization. The expectation is that terrorist organizations would serve as commitment tools that increase the loyalty of suicide bombers to their missions through material and non-material incentives. Findings demonstrate that when terrorist organizations are involved in the planning and execution of suicide terrorist attacks, not only do they increase the lethality of these attacks but they also accentuate the tactical advantages of suicide terrorism. These findings suggest that despite the recent upsurge and concern about lone wolf terrorism, the lethality and security impacts of suicide terrorism continue to be driven by terrorist organizations.     

Political crises,strategic choices,and terrorism: The rise and fall of the Uruguayan Tupamaros

In this article we offer a first attempt at providing a set of universal grading criteria for determining on what basis, and how far, an item of discursive content can be considered “terroristic.” In doing so, we draw loosely on the existing COPINE scale for child abuse images. The scale described in the article is not intended to reflect actual risk of engagement in terrorist violence, nor is it intended to have evidential validity in relation to offenses in certain jurisdictions relating to “terrorist publications.” Rather, by formalising assumptions which seem already to be latent in the literature on terrorist use of the Internet, it aspires to serve as a starting point for a more methodologically coherent approach to relationships between content—particularly online content—and terrorism.
