FIGHTING TERRORISM: ARE MILITARY MEASURES EFFECTIVE? EMPIRICAL EVIDENCE FROM TURKEY

The present article aims at investigating the causal relationship between defense spending and terrorism in Turkey using the Autoregressive Distributed Lag (ARDL) bounds testing procedure and Granger‐causality analysis. The findings reveal that there exists a unidirectional causality running form terrorist attacks to defense spending as expected, but not vice versa. In the light of this finding it can be inferred that military anti‐terrorism measures alone are not sufficient to prevent terrorism.     

An Integro-Differential Approach To Terrorism Dynamics

This article introduces integro-differential equations as a new technique to study terrorism dynamics. An integro-differential equation is a mathematical expression that contains derivatives of the required function and its integral transforms. The technique is applied to two different dynamic models in terrorism: terrorism and tourism, and terrorist innovations. In the first model the number of tourists that appears in an integral term and also in a derivative term is impacted by the number of terrorists. In the second model the integro-differential equation for terrorist innovations relates them to terrorist attacks. The article shows how to solve, analyze, interpret, and deal with integro-differential equations. Integro-differential equations shed light on aspects of the models ignored when other techniques are used. This is particularly important for the evaluation of current counterterrorist policies, as well as to the formulation of new ones.     

SUICIDE TERRORISM AND THE BACKLASH EFFECT

This paper presents a game‐theoretic model of suicide terrorism containing three agents: the terrorist leader; a targeted government; and potential terrorist supporters. Supporters join the terrorist group if they gain more from their participation than from their economic opportunities. Preemptive measures by the government can result in a backlash that encourages recruitment through new grievances. Suicide attacks can also lead to recruitment. Increases in preemption costs and/or economic opportunities can reduce the overall level of terrorism, while increasing the proportion of suicide to normal attacks. An increase in the effect of preemption on recruitment, or the propaganda effect of suicide bombings has the opposite effect of increasing normal and suicide attacks, but decreasing the proportion of suicide to normal attacks in the terrorist organization’s strategy profile.     

Defence industries adjusting to change 1

This paper analyses the impact of terrorist activity on international tourist flows. To this end, we have estimated a cross‐sectional gravity equation for tourism from the G‐7 countries to a sample of 134 destinations over the period 2001–2003. Within this framework, we evaluate the deviation from ‘normal’ tourist flows due to terrorist activity, which is considered as negative advertising for the affected country. The analysis suggests that both domestic victims and international attacks are relevant factors when foreign tourists make their choice. This result is robust under alternative specifications. Moreover, the impact of terrorism is more severe in developing countries.     

Dangerous work: Terrorism against U.S. diplomats

The goal of diplomats is to represent their countries’ interests through diplomacy, not arms. Because they are not military personnel, they may be perceived as at lower risk of being the target of terrorists. However, recent events have called this perception into question. Despite this danger, there has been little research on terrorist attacks against diplomats. Drawing on the terrorism studies literature, this article argues that diplomats are targeted more than non-diplomatic targets in countries where certain U.S. foreign policies are implemented. An empirical analysis of 471 attacks against U.S. diplomats from 1970 to 2011 reveals that while U.S. alliances and foreign aid increase the likelihood of attacks against diplomats, U.S. military intervention and civil war, on the other hand, increase the risk of terrorism against non-diplomatic targets. This finding is relevant because it shows terrorist attacks against diplomats result from certain types of foreign policy.     

Weakest‐link attacker‐defender games with multiple attack technologies

In this article, we examine a model of terrorism that focuses on the tradeoffs facing a terrorist organization that has two qualitatively different attack modes at its disposal. The terrorist organization's objective is to successfully attack at least one target. Success for the target government is defined as defending all targets from any and all attacks. In this context, we examine how terrorist entities strategically utilize an efficient but discrete attack technology — e.g., suicide attacks — when a more conventional mode of attack is available, and the optimal anti‐terrorism measures.© 2012 Wiley Periodicals, Inc.

TERRORISM AND DETERRENCE POLICY WITH TRANSNATIONAL SUPPORT 1

This study provides an explanation of terrorism by examining interactions between the terrorist group with a minority as a potential pool of recruits and the government supported by a majority. A hawkish deterrence policy makes it more risky for terrorists to launch attacks, but heightens the anti‐government feeling of the terrorist group. In addition, the payoff for the government depends not only on the payoff loss associated with the level of terrorism, but also on the political payoff from the action itself of adopting a hawk policy due to its politicians’ vested interests. We first show that whether the deterrence policy should be ‘hawk to ‘dove is closely dependent on the relationships among the risk associated with terrorism, the anti‐government feeling of the terrorist group, and the political payoff for the government. This study then introduces transnational support enhancing the capability of a terrorist group to intensify its activity and shows that the emergence of transnational support may cause the government to reform its deterrence policy from ‘dove’ toward ‘hawk,’ with terrorism intensified in the society.     

ON ETHNIC CONFLICT AND THE ORIGINS OF TRANSNATIONAL TERRORISM

Using the ITERATE dataset, we explore the origins of transnational terrorist activity, from 1982 through 1997, in 118 countries. We model terrorism, not as a function of a nation’s ethnic, religious or linguistic fractionalization, but as an independent measure of perceived ethnic tensions. When we control for institutional quality, evidence that political rights and civil liberties mitigate the terrorism‐producing effects of ethnic tensions exists only since 1990. Economic freedoms, on the other hand, robustly reduce the number of terrorist attacks originating in ethnically tense societies.     

Remittances and terrorism: A global analysis

This paper is the first global investigation of the relationship between remittances and terrorism. To discern this relationship, we draw terrorism event data from the Global Terrorism Database and International Terrorism: Attributes of Terrorism Events. When a host of standard terrorism controls is employed, lagged remittances as a share of gross domestic product have a positive and significant impact on both domestic and transnational terrorist attacks. For the venue country’s viewpoint, lagged remittances have a greater marginal impact on domestic than on transnational terrorism. However, when we investigate remittances to the home country of the perpetrator, lagged remittances have the greatest marginal impact on transnational terrorism. Throughout our investigation, standard terrorism controls perform according to our priors and those of the literature, lending credence to the isolation of the impact of remittances. We also account for endogeneity concerns.

Spatial Distribution of Minority Communities and Terrorism: Domestic Concentration versus Transnational Dispersion

Qualitative studies of terrorist movements frequently highlight the importance of diaspora communities as important factors in producing and sustaining terrorist activity in countries. The underlying theoretical argument is that bifurcation of tight-knit minority communities between countries nurtures separatist or irredentist sentiments among affected community members, thus prompting terrorist activity, while minority community members in other countries might mobilize financial and political resources to support terrorist activity among their compatriots. In this study, we empirically test whether transnational dispersion, versus domestic concentration, of minority communities in countries produces higher incidents of terrorism. Conducting a series of negative binomial estimations on a reshaped database of around 170 countries from 1981 to 2006, derived from the Minorities at Risk database and the Global Terrorism Database, we determine that both transnational dispersion of kin minority communities and domestic concentration of minorities within countries increase terrorism and that transnational dispersion is a particularly robust predictor of terrorist attacks.     

“后拉登”时代国际反恐形势的变化及对策

本·拉登被击毙后,国际恐怖主义及反恐形势发生了深刻变化,对美国、恐怖组织、国际社会以及我国都产生了不同的影响,防范新一轮恐怖袭击已成为我国现实而紧迫的课题。为此,我们应结合自身实际,从意识形态、政治外交、反恐准备、应急处置等各个方面分析研判,制定对策有效应对。     

Ethnic groups,political exclusion and domestic terrorism

This study examines whether the exclusion of ethnic groups from political power is an important contributing factor to domestic terrorism. To empirically test this question, we employ a negative binomial regression estimation on 130 countries during the period from 1981 to 2005. We find that countries in which certain ethnic populations are excluded from political power are significantly more likely to experience domestic terrorist attacks and to suffer from terrorist casualties; furthermore, ethnic group political exclusion is a more consistent and substantive predictor of domestic terrorist activity than general political repression or economic discrimination.     

Warning of Terror: Explaining the Failure of Intelligence Against Terrorism

Many scholars and analysts have studied intelligence failure and surprise and developed theories to explain disasters such as the attack on Pearl Harbor. Others, especially since the 9/11 attacks, have examined the rising threat of terrorism and see it as posing a particularly difficult challenge for the intelligence community. But little work has been done to integrate the earlier literature on intelligence failure with the newer threat of terrorist attack. This article attempts such an integration, by examining the bombing of the US Marine Barracks in Beirut in 1983; it concludes that most studies of the Beirut bombing are mistaken in their assessment of the role played by intelligence in that disaster, and suggests that our understanding of intelligence failure against surprise attacks needs to be revised in the age of terrorism.     

以色列反恐情报战略探讨

以色列是世界上第一个遭受国际恐怖主义威胁的国家。但通过明确分工和行之有效的反恐措施,以色列已经能够对付不断升级的恐怖主义威胁。自“9·11”事件以来,全球许多国家都开始向以色列求教国土安全方面的知识和专业技术。     

Military support and transnational terrorism

Analysing the relationship between the provision of military support and the probability of becoming the target of a terrorist attack, this paper contributes to the literature on the causes of transnational terrorism. We find that deployment of military troops of country X in country Y increases the probability of a terrorist attack on citizens of country X by a terrorist group located in country Y. Exporting weapons to country Y seems to increase the probability of being attacked by the terrorists of this country Y as well. Deploying materials, however, does not seem to significantly influence the probability of attack. Including lagged values for our military support variables ensures that the causality direction is from military support to terrorist attacks. Moreover, these results indicate that while the effect of military deployment on the probability of attack lasts for more than 1 year, the effect is rather short-lived.

THE EFFECT OF 9/11 ON US EXPORTS AND IMPORTS OF TOURISM

Several studies have investigated whether the terrorist attacks of September 11, 2001, have had an ongoing or merely transitory effect on US trade in tourism. All conclude in favor of the latter. However, limitations in either the data and/or methodology employed by these studies give cause to query their findings. The present study avoids these limitations and finds strong evidence that, once other factors are held constant, real US exports and imports of tourism have both remained significantly below their pre‐2001 level.     

A1 Qaeda and the radical Islamic challenge to western strategy

The September 11 global crisis prompted by the attacks on the World Trade Center and the Pentagon raises major questions concerning the nature and trajectory of terrorism in the post-Cold War global order. Hitherto, terrorism has been largely debated by analysts at the level of nation states. Terrorist and insurgent movements have also been largely anchored in nationalist and ethnic power bases even when they have sought to mobilise a transnational ideological appeal on religious or class grounds. There have been a few exceptions to this pattern such as the alliance between the German Baader-Meinhof group and the Japanese Red Army Faction, but even such international alliances as this did not, until at least the 1980s, presage anything like a global terrorist network necessitating a global strategic response. This study examines terrorism and global strategic responses.
