This work is about how the United States military has become dependent on networked technology. As arguably the largest contributor to national security, it has become so dependent that its chief doctrine integrates networked technology into nearly every specialty, with particularly intense focus on Network Centric Warfare. As the military’s old guard is replaced by the highly technical Millenial Generation, there is cause to pause when assuming this techno-acuity brings nothing but advantage and success. Vulnerabilities stemming from such extensive dependence offer opportunities for exploitation that have not gone unnoticed. The first step to moving forward from this point is to fully understand the extent to which the military has become dependent on computer networks. It might be the Millenials’ war today, but it would be quite unwise for the United States military to think about it and fight it in a purely Millenial way. 相似文献

Recent elections in Latin America, such as those of Mauricio Macri in Argentina, Horacio Cartes in Paraguay, and the impeachment process of Dilma Rousseff in Brazil, point to a new direction in Latin American politics and away from the “hard left;” they also point to a new momentum in the security relationship between the US and Latin American countries. Former US President Obama’s 2016 trip to Cuba and Argentina was a clear demonstration of this new security paradigm and also a clear indication that there is a new momentum brewing in the US towards a rethinking and reshaping of security strategies and mindsets. This article will explore the multidimensional security relationship between the US and Latin American countries in light of recent changes in the US’ posture toward the region. 相似文献

This article reappraises the two most-studied country cases of military outsourcing: the USA and the UK. It argues that the contemporary wave of military contracting stretches back to the beginning of the cold war and not only to the demobilisation of armies in the 1990s or the neoliberal reforms introduced since the 1980s. It traces the political, technological and ideational developments that laid the groundwork for these reforms and practices since the early cold war and account for its endurance today. Importantly, it argues that a persistent gap between strategic objectives and resources, i.e. the challenge to reconcile ends and means, is an underlying driver of military contracting in both countries. Contemporary contracting is thus most closely tied to military support functions in support of wider foreign and defence political objectives. Security services in either state may not have been outsourced so swiftly, if at all, without decades of experience in outsourcing military logistics functions and the resultant vehicles, processes and familiarities with public-private partnerships. The article thus provides a wider and deeper understanding of the drivers of contractualisation, thereby improving our understanding of both its historical trajectory and the determinants of its present and potential futures. 相似文献

Postmodern contradictions in postcolonial Nigeria have led to the fetishisation of alternative local security measures often labelled as vigilante activities. The profiling of these groups as ethnic militia often undermines their essential bid to provide security while delimiting security needs to the physical. The fallouts of such profiling are frictions between federal security agents and ethnic-based security groups, often resulting in violence, as exemplified by the 7 May 2013 incident between the Nigerian federal security agents and the Ombatse. This study focuses on the emergence and activities of the Ombatse as an alternative security apparatus of the Eggon. It presents three years of field research which entailed the use of ethnography, key informant interviews and observation. The findings reveal that the Ombatse emerged to assert historical legitimacy for both the physical and spiritual securitisation of the Eggon through a return to the ancestral ways of social engineering. The study considers the security challenges in Nigeria, and also situates the Eggon historical context within political, religious, sociocultural and economic intersections of securitisation. It concludes that the Ombatse situates its legitimacy within the Eggon past and retains its relevance through the holistic focus of providing both physical and spiritual security. 相似文献

“空海一体战”是美国的一种新型作战理论,是在20世纪80年代“空地一体战”等诸多战法及兵种妥协基础上形成的一种新型军事战略,旨在通过空海军力量的配合,进行近域作战,以抵消对手的反进入/区域拒止能力,取得战争的主动权与控制权.“空海一体战”作为美国战略重心东移的重要角力点与支撑要素,在美国亚太战略中的作用举足轻重,对亚太周边国家尤其是中国的国家安全构成重大威胁,为此有必要对其理论渊源、发展目标、策略行动及障碍缺陷进行剖析与解构,为中国维护国家安全,构建良好的国家安全环境提供战略储备与智力支持. 相似文献
