The United States has multiple nuclear detection initiatives to secure against a terrorist nuclear attack, including the Container Security Initiative, installation of radiation detectors at U.S. border points of entry, and establishment of the Domestic Nuclear Detection Office (DNDO). The current nuclear detection system architecture falls short of being able to reliably catch fissile nuclear material in transit, specifically shielded Highly Enriched Uranium (HEU) and Plutonium (Pu), both within the US and abroad. Checkpoints at border crossings can be circumvented, and no adequate system is under development to deter the transport of fissile materials. Using nuclear link-budget calculations, we show why a network relying primarily on handhelds, fixed detectors, and portals is not sufficient. We examine the technical, economic, and operational feasibility of a comprehensive national network incorporating in-vehicle detectors to reliably detect and deter the transport of fissile material inside the vehicle itself.  相似文献

Scholars have expressed doubts about the ability of counterterrorism to cope with suicide bombings, resulting in tit-for-tat or loop-like and repetitive violence and counter-violence without meaningful, let alone decisive results for the stronger side. Such skepticism may explain why so much of the recent literature on terrorism and insurgency is focused on the factors motivating the challenger rather than upon the insurgent's capabilities. This article demonstrates the extent to which Israeli offensive measures have reduced considerably the impact of Palestinian violence on the Israeli protagonist corroborating research that counterterrorism should adopt an offensive escalating strategy against the insurgent.  相似文献

This article is an extended book review of the Turkish book Commanders' Front (Komutanlar Cephesi, Istanbul: Detay Publishing, 2007), written by prominent Turkish journalist Fikret Bila, who compiled a series of interviews with retired Turkish military commanders and two former presidents. It provides a foreign perspective on counterinsurgency/terrorism strategies and lessons learned from Turkey's small war against the Kurdistan Workers' Party (PKK). The interviews reveal the generals' views on Turkey's long-standing fight with the PKK, discussing topics ranging from the social aspect of the PKK problem to mistakes made in arming local militia. In addition, it presents the Turkish perspective on US policy in Iraq.  相似文献

ABSTRACT

Al Qaeda following 9-11 experienced a period of stagnation which it sought to remedy through a project of re-branding. Critical of this approach, Islamic State claimed that al Qaeda was an elitist organization that had facilitated the stagnation of the Salafi Jihadist project. In an attempted to claim dominance over the jihad, Islamic State’s endeavored to discredit al Qaeda through a process it presented as ideological correction, linked to Islamic eschatology, sectarian agitation, permissive violence, and the caliphate. Following Islamic State’s acquisition of vast territory in Iraq and Syria, arguments proliferated that Islamic State had surpassed al Qaeda. As the caliphate has collapsed what effects will this have on al Qaeda’s fortunes and strategy? It is argued that Islamic State has provided al Qaeda’s strategic approach with renewed vigour to help ensure its survival and pursue resurgence. Al Qaeda acting in concert with the meta-strategy for survival concept, has altered an existential threat into an advantage through disavowing Islamic State’s methods, continuing to engage with localism, and pursuing rebranding by positioning itself as a moderate alternative. The cases of al Qaeda affiliates in Yemen, Syria, West Africa, and South Asia are instructive in assessing the effectiveness of al Qaeda’s resurgence.  相似文献
