ABSTRACT

Since 2002, NATO's territorial missile defense has evoked continuous debates between NATO states and the Russian Federation. Thirteen years have passed without reaching a common denominator. This article provides a comprehensive overview of the historical background of the debate and the technical details of the missile defense system, highlighting its shortcomings and the state of its deployment process. It also contrasts the military-technical and political arguments of both sides, before addressing the applicable norms of international law to highlight violations and the effect of this noncompliance on existing arms control measures.  相似文献

In the aftermath of September 11, 2001 and Hurricane Katrina, the United States government has spent tens of billions of dollars to improve the nation's ability to respond to a natural disaster or terrorist attack, but the emphasis on immediate first response has left many long-term environmental, political, and technological challenges unaddressed. Although a dirty bomb attack is unlikely to yield the same amount of physical devastation and death as caused by Katrina or a nuclear weapon, the social, psychological, and economic impact would be enormous. At present, however, the United States lacks the technology necessary to decontaminate a large, densely populated urban area under time, political, and economic constraints. This article reviews past cleanup experiences and current decontamination capabilities to consider the long-term implications of a dirty bomb, identifies weaknesses in America's existing response capabilities, notes possible areas of political friction, and considers the implications of the failure to adequately prepare. Having the appropriate decontamination techniques established and long-term plans in place before an incident occurs will significantly improve the government's ability to protect public and environmental security, establish a viable decontamination strategy, allow residents to return to their homes, and get the local economy back on its feet.  相似文献

MONGOLIA     
Formed according to broad principles laid out by the United Nations, nuclear-weapon-free zones (NWFZs) play an important role in promoting nuclear nonproliferation, paralleling and complementing the Treaty on the Non-Proliferation of Nuclear Weapons. But the traditional regional treaty-based path to establishing NWFZs is not open to all states. Owing to various factors, some countries cannot realistically follow the path of states that have established traditional NWFZs. Mongolia, having declared itself a single-state NWFZ in 1992 and gained UN General Assembly recognition of this status in 1998, may provide an example for other countries to follow. This viewpoint presents Mongolia's case as a state seeking to acquire a nontraditional nuclear-weapon-free status despite unfavorable geopolitical circumstances. The case of Mongolia clearly demonstrates that the creation of a credible, single-state NWFZ status is possible, but demands the support and flexibility of both neighboring states and the nuclear weapon states.  相似文献

Russian naval nuclear fuel and reactors pose both proliferation and environmental threats, ranging from the possible theft of highly enriched uranium fuel to the radioactive contamination of the environment, whether due to accident, neglect, or sabotage. Current conditions at Russian naval bases, together with a history of accidents and incidents involving Russia's nuclear fleet, make a convincing case for the large-scale assistance that the G8 is now providing to improve the safety and security of Russian naval reactors and fuel. However, virtually no data has been released to allow accurate, reliable, and independent analysis of reactor and fuel properties, risking misguided international efforts to assist in the areas of nuclear cleanup, nonproliferation, and security. This article identifies and assesses relevant properties and developments related to reactor and fuel design, provides a comprehensive presentation of Russian nuclear naval technologies, and examines technological trends in the context of proliferation and environmental security.  相似文献

In signalling its wish to participate in the Additional Protocol at an early stage, Sweden took several steps at the national level long before it actually ratified the protocol in May 2004. In 1998, the Swedish Nuclear Power Inspectorate (SKI) initiated a project to conduct a historical survey of Swedish nuclear weapons research for the period 1945–72. Sweden thus took an important step for the sake of transparency. SKI worked out a general model of how a nationally based survey could be designed, and gradually other states approached SKI in order to learn more about the methods and goals of the historical surveys. In 2002, a cooperative project was initiated between Sweden and Estonia, Latvia, and Lithuania. Finland joined the cooperative effort, and it thus became a dialogue and project carried out by five neighboring states to make national surveys. This article presents summaries of the national reports from Sweden and the Baltic states.  相似文献

Recently, post-explosion nuclear forensics, or nuclear attribution, has gained a new spotlight within the nuclear weapons scientific and policymaking community. Academics are beginning to ask whether post-explosion forensics might create a replacement for an international nonproliferation regime, or at least offer a fallback option to deter states and individuals from selling nuclear materials. This paper examines current attribution technology from unclassified literature and finds the technology to be well developed but not foolproof, such that nuclear attribution currently provides little deterrent value. If current capabilities were publicized more thoroughly and if the post-explosion process of assessing the evidence were internationalized, states and intermediate actors might be deterred more effectively. Developing a nuclear fingerprint database is also discussed. While useful, its impact on deterrence would be minimal.  相似文献

An increasing number of countries recognize the special risks of nuclear terrorism associated with the civilian use and storage of and commerce in highly enriched uranium (HEU). They are especially concerned that non-state actors might gain access to HEU and use it to build and detonate improvised nuclear devices. The risk is aggravated by the very large global stocks of HEU, some of which are inadequately protected. Although HEU has few commercial uses, and most experts believe it is technically feasible to substitute low-enriched uranium for HEU in nearly all civilian applications, efforts to reduce HEU stocks have been impeded by a variety of economic, political, and strategic considerations. This article analyzes the nature of these impediments and discusses what is required to overcome them.  相似文献

Based on the first-person account of coauthor Pierre Billaud, a prominent French participant, this article describes for the first time in such detail the history of the development of the French hydrogen bomb in the 1960s and the organization of military nuclear research in France. The authors illustrate the extent to which French defense and governmental authorities did not support research on thermonuclear weapons until 1966. Billaud, a project insider, relates the historical episodes that led to France's successful 1968 thermonuclear test, including the names of the individuals involved and how a timely tip from a foreign source hastened the success of the first H-bomb test.  相似文献

THE NPT     
This article assesses the successes and failures of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) since its creation in 1968 by developing and applying a set of “metrics” to each of the NPT's substantive articles as well as to its withdrawal provisions. In light of this analysis, the article also puts forward some specific proposals for strengthening the NPT and its implementation, with a view to the debate and decisions at the upcoming 2010 NPT Review Conference. A concluding section turns explicitly to the 2010 NPT Review Conference and proposes pursuit of agreement on three NPT Action Plans: one for nonproliferation, one for peaceful uses, and one for nuclear disarmament. Combining vision and practicable steps, these Action Plans would set out a roadmap for action between the 2010 and the 2015 NPT Review Conferences. They could provide a foundation for substantive exchanges—in this case, on progress toward their implementation—during the preparations for the 2015 conference.  相似文献

“Nuclear threshold states”—those that have chosen nuclear restraint despite having significant nuclear capabilities—seem like the perfect partners for the reinvigorated drive toward global nuclear disarmament. Having chosen nuclear restraint, threshold states may embrace disarmament as a way to guarantee the viability of their choice (which may be impossible in a proliferating world). Supporting disarmament efforts affirms their restraint, both self-congratulating and self-fulfilling. Additionally, the commitment to their non-nuclear status springs at least in part from a moral stance against nuclear weapons that lends itself to energetic support of global disarmament. However, threshold states also offer significant challenges to the movement for nuclear weapons elimination, in particular in relation to acquisition of enrichment and reprocessing facilities. This article analyzes both the challenges and opportunities posed by threshold states by examining the cases of Brazil and Japan.  相似文献
