How do states use nuclear weapons to achieve their goals in international politics? Nuclear weapons can influence state decisions about a range of strategic choices relating to military aggression, the scope of foreign policy objectives, and relations with allies. The article offers a theory to explain why emerging nuclear powers use nuclear weapons to facilitate different foreign policies: becoming more or less aggressive; providing additional support to allies or proxies, seeking independence from allies; or expanding the state’s goals in international politics. I argue that a state’s choices depend on the presence of severe territorial threats or an ongoing war, the presence of allies that provide for the state’s security, and whether the state is increasing in relative power. The conclusion discusses implications of the argument for our understanding of nuclear weapons and the history of proliferation, and nonproliferation policy today.  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

Recent research has led to several surrogate multiplier search procedures for use in a primal branch-and-bound procedure. As single constrained integer programming problems, the surrogate subproblems are also solved via branch-and-bound. This paper develops the inner play between the surrogate subproblem and the primal branch-and-bound trees which can be exploited to produce a number of computational efficiencies. Most important is a restarting procedure which precludes the need to solve numerous surrogate subproblems at each node of a primal branch-and-bound tree. Empirical evidence suggests that this procedure greatly reduces total computation time.  相似文献

The traditional forms of Chechen society - the extended family, the clan, the religious brotherhood - have proven to be effective building blocks on which to construct network-based structures both for modern organized crime and also for fighting a guerrilla war against the Russians in Chechnya. These networks have evolved in the face of external pressure and are proving durable and successful, even as they are supplemented by separate networks of Islamic extremists, devoted both to guerrilla warfare and also a campaign of terrorism within Russia.  相似文献

ABSTRACT

The period 1833 to 1840 witnessed a brutal civil war in Spain waged between insurgent Carlists and the government Cristinos. The Carlists managed to secure reliable territorial control only over one part of Spain (upland Navarra and rural parts of the neighbouring Basque provinces). Although pockets of armed Carlism flourished elsewhere in Spain, especially in Catalonia, Aragón and Galicia, these insurgents were ineffective at coordinating actions. The Carlist court in the Basque country tried to break its strategic blockade by launching a series of expeditions into Cristino-held territory in the hope of destabilising the Madrid regime and consolidating distant insurrections. This article explains how and why these expeditions scored tactical victories but strategic failures. In particular it argues that Carlist raiding strategy was a failure, for its use of violence against real and imagined enemies in marginal and Cristino areas of control alienated civilian support.  相似文献
