Despite the burgeoning literature on Russia’s renewed power politics, little attention has been paid to the fact that US reactions towards Russia’s military interventions were all but coherent. The USA has chosen weak measures in Georgia in 2008 (shaming) compared to its assertive response in Ukraine in 2014 (sanctions, hard deterrence). This article assesses the explanatory power of neorealist, liberal and constructivist theories for the variation in US reactions towards Russian interventions in Georgia and Ukraine. Our argument is that the constructivist perspective explains the cases best as it highlights the power and communality of normative assessments. The Ukraine crisis was perceived by the USA as a violation of core international norms, especially the non-use of force and the principle of territorial integrity. Relevant international norm carriers shared this assessment of the conflict. In contrast, the perception of the Georgian war centred on the issue of democracy promotion. While democracy is an important aim of US foreign policy, it does not summon the same normative importance as general principles of international law. Furthermore, the perception of the Georgian war remained contested among Western allies, which decreased the communality of the normative assessment.  相似文献

This article traces the evolution of the EU strategic reflection which culminated in the publication of the EU Global Strategy (EUGS) in June 2016. It explains the choices made by EU High Representative Federica Mogherini over this time period—including both the initial strategic assessment and the final EUGS. It provides a behind the scenes view on the players, the organization and the methods of work used to produce a strategic vision for the EU’s role in the world.  相似文献

Australian defence strategy is disjointed and incomplete. Some would say that it is non-existent. Either way, this paper argues that Australia’s underwhelming approach to defence is the product of a crippling geographically focused strategic dichotomy, with the armed forces historically having been structured to venture afar as a small part of a large coalition force or, alternatively, to combat small regional threats across land, sea, and air. However, it is argued that Australia can no longer afford to drift between these two settings and must take measures to define a holistic “full spectrum defence” strategy and develop capability to fight effectively and independently across all domains of the twenty-first century-battlespace: land, sea, air, space, and the cyber realm.  相似文献

Following the terrorist attacks against the US in 2001, the Bush administration reaffirmed the Dover ban, the policy that prohibited press coverage of military coffins arriving at Dover Air Force Base from conflicts abroad. Conventional wisdom holds that the Bush administration enforced the ban in the hope of maintaining public support for the wars in Afghanistan and Iraq. This understanding, though, is incomplete. If the Dover ban were enforced only in response to eroding public opinion, then other coalition states would have responded likewise to this shared incentive. I argue instead that maintaining public support is only one factor among many that led the US to uphold this policy. In addition to considering the influence of factors such as perceived media bias and casualty aversion, I focus on necropolitics and the related impetus for governments to regulate the observation of death. Through this interpretation, part of the American response to the involuntary loss of sovereignty on 9/11 was to exercise control over the observation of death by enforcing the Dover ban. Through comparing the press policies of the US, the UK, and Canada, I show that the necropolitical blow to sovereignty that only the US experienced triggered a repressive policy that only the US was able to maintain.  相似文献

The article is devoted to problems of defining quantitative criteria for the physical protection system (PPS) effectiveness of nuclear facilities. The article briefly describes the scheme of the PPS development used in the nuclear industry in Russia, gives a review of existing approaches to defining the minimal acceptable value of the system's effectiveness, and reveals advantages and disadvantages of the approaches. The article describes in detail an approach based on facility categorization by potential losses and a technique of defining the minimal acceptable value of the PPS effectiveness developed on its base.  相似文献

Nowadays, Chemical-Biological-Radiological-Nuclear-explosive (CBRNe) risks are one of the world's main safety concerns. The radiological disasters of Fukushima and Chernobyl, the chemical events of Seveso or the release of Sarin in the Tokyo Subway, the biological emergencies such as the H1N1 flu or the recent Ebola outbreak, and recent news about the availability of non-conventional weapons acquired by fundamentalist organisations represent evidence of potential future threats. CBRNe risks are a real and global threat. The University of Rome, Tor Vergata, in collaboration with the most important Italian and international bodies working in the field of CBRNe safety and security, and supported by the North Atlantic Treaty Organisation and the Organisation for the Prohibition of Chemical Weapons, organises International Masters Courses on the Protection against CBRNe events. Within this framework, a Table-Top Exercise was planned, in collaboration with the Italian Ministry of Interior and Ministry of Defence. The scenario, the logistic organisation, on-going adjustments during the exercise and the outcomes are presented here and analysed.  相似文献
