This paper explores the notion that US efforts to evade the political costs of war paradoxically contribute to the subsequent exacerbation of costs over time. Leaders seek to purchase political capital in the short term by limiting the costs and requirements of military operations, but in doing so cause strategic and political liabilities to mount in the long run. While identification of such behaviour is not new, insufficient attention has been devoted to explaining its causes, dynamics, and manifestations in relation to key decisions on and in war. Evidence derived from studies of recent American discretionary campaigns is analysed to advance an argument with respect to this pattern of self-defeating strategic behaviour. 相似文献

International concern over nuclear terrorism has grown during the past few decades. This has driven a broad spectrum of efforts to strengthen nuclear security globally, including the widespread adoption of radiation-detection technology for border monitoring. Detection systems are now deployed at strategic locations for the purported purpose of detecting and deterring the smuggling of nuclear and radioactive materials. However, despite considerable investment in this area, few studies have examined how these programs are implemented or the operational challenges they face on a day-to-day basis. This article seeks to address this with a focus on radiation-detection efforts at maritime facilities. Utilizing practitioner interviews and a survey, this article identifies the factors that influence the planning and use of these systems in this fast-moving environment. The results clearly demonstrate that the implementation of these systems varies significantly across different national and organizational contexts, resulting in a fragmented global nuclear-detection architecture, which arguably undermines efforts to detect trafficked nuclear-threat materials. Greater consideration should therefore be given to developing international standards and guidance, designing and adopting tools to support key parts of the alarm assessment process, and broader sharing of good practice. 相似文献

This article examines contemporary modes of American warfare. It posits the concept of “vicarious warfare” as a means of capturing prominent patterns in warfighting approaches. Although rooted in long-standing traditions of military practice, vicarious warfare is sufficiently novel as to be identifiable as a distinct phenomenon. The precise manifestation or combination of vicarious methods vary according to the specific circumstances and political contexts prevailing in different theaters. However, America’s general preference is to fight its wars by delegating tasks to proxies and limiting exposure of its own military to danger. Where U.S. forces are employed directly, this takes place largely in the shadows. Such approaches have clear attractions, offer undoubted tactical advantages, and permit successive administrations to maintain a persistent tempo of operations that evades rigorous democratic scrutiny. Yet, prominent cases and numerous studies suggest that vicarious warfare has a high potential to generate counterproductive effects and significant strategic harm. 相似文献

This article examines critically the literature of hybrid war and evaluates the countermeasures often proposed. It explains the concept of hybrid warfare and its varied interpretations, illustrating how it is a manifestation of current anxieties in armed conflict. The selection of the literature is based on works that are referenced, that offer a scientific approach, and which review either the phenomenon of hybrid warfare or its countermeasures empirically. Unscientific works have been omitted. The analysis of the literature presented here shows that the antidotes to ‘hybridity’ lie not in the operational or tactical sphere but in strategic and political domains. 相似文献

This article is the latest in a series of published articles systematically examining Afghan Presidential and legislative elections. Structural problems including fraud, ethno-linguistic block voting, and the Single Non-Transferable Vote have had significant impacts on the development of Afghan democratic elections. The challenge now facing the current Afghan government and future elections is the daunting task of uniting the Afghan people while not repeating the electoral mistakes of the past. The tricky balancing act of fostering an overarching national identity without being perceived as privileging particular identities requires strong leadership and a willingness to challenge traditional ethnic, linguistic, and religious norms when need be. Karzai and Ghani Administrations have seriously failed relative to this dynamic. 相似文献

ABSTRACTThe paper’s goal is to analyses the potential of the Iranian defence industry, including both research-and-development and production capabilities. It is argued that, despite official statements about the great power and sophistication of the Iranian defence industry, in reality its capabilities are very limited and cannot meet the operational needs of the Iranian armed forces. At the same time, it is argued that many official releases, which are abundantly available in the Iranian press and often unthinkingly repeated by the Western media, do not present the real and value of military products, but are rather a tool for deception and propaganda. 相似文献

The malaise that the United States, and the West, have experienced in recent campaigns stems in large part from unclear thinking about war, its political essence, and the strategies needed to join the two. Instead, analysis and response are predicated on entrenched theoretical concepts with limited practical utility. The inadequacy of understanding has spawned new, and not so new, terms to capture unanticipated trends, starting with the re-discovery of “insurgency” and “counterinsurgency” and leading to discussion of “hybrid threats” and “gray-zone” operations. New terminology can help, but the change must go deeper. Challenging analytical orthodoxy, this article sets out a unifying approach for the study of political violence, or more accurately: violent politics. It provides a conceptual foundation that helps to make sense of recent shifts in warfare. In effect, it offers sorely needed theoretical insights into the nature of strategy and guides the process of responding to nontraditional threats. 相似文献

This article gives an overall assessment of ISIS’s conventional conduct of combat operations by examining their warfighting functions patterns. In sum, the approach of ISIS comprised fundamental principles: their weapons can be organized into categories, purposeful combination of these forces in keeping with the concept of combined arms combat, and hierarchical command and control executed by experienced commanders. ISIS combat groups combined the elements of formation and firepower as well as movement and mobility. The paper concludes that ISIS obviously had a vast range of conventional capabilities at its disposal and was thus able to conduct major operations. 相似文献
