As the potential for the involvement of corporations in the manufacture of nuclear weapons has increased, particularly through dual-use technology, global regulation has failed to keep pace. Where regulation of private corporations does exist, in the form of treaties, UN resolutions, or more informal arrangements, the obligations fall only on states. This state of affairs is a result of international law's traditional deference to state sovereignty; yet, it has led to significant shortcomings in the global regulatory regime, where states are unwilling or unable to meet their obligations. While radical departures from the traditional model of international law might remove the regulatory gaps caused by noncompliant states, such changes are unrealistic in the current political climate. More realistic changes must be focused on, offering greater recognition of the role of private corporations in nuclear proliferation and increasing state compliance with existing regulation.  相似文献

For many years, non-nuclear weapons states have sought binding commitments from nuclear armed states that they would not be the victim of either the threat or use of nuclear weapons—so-called negative security assurances (NSAs). The nuclear weapon states have traditionally resisted granting such unconditional NSAs. Recent U.S. efforts to use nuclear deterrence against the acquisition and use by other states of chemical, biological and radiological weapons, however, have further exacerbated this divide. This article analyzes the historical development of NSAs and contrasts U.S. commitments not to use nuclear weapons with the empirical realities of current U.S. nuclear weapons employment doctrines. The authors conclude that NSAs are most likely to be issued as unilateral declarations and that such pledges are the worst possible manner in which to handle the issue of security assurance.  相似文献

This article predicts that the nuclear weapon states may opt sooner for nuclear elimination than generally expected. This delegitimation of nuclear weapons is due to five factors whose importance has grown since the mid-1990s: nuclear proliferation, the risk of nuclear terrorism, the nuclear taboo, missile defence, and the increased importance of international law. The article starts with categorizing nuclear weapons policies: nuclear primacy, maximum deterrence, minimum deterrence, existential deterrence, and post-existential deterrence. The nuclear weapon states will probably shift their policies from nuclear primacy (US), maximum deterrence (Russia), minimum or existential deterrence (UK, France, Israel, China, India, Pakistan, North Korea) to post-existential deterrence (or elimination), taking one step at a time.  相似文献

This article applies the concept of nuclear ambivalence to the case of the Islamic Republic of Iran. Nuclear ambivalence differs from other approaches to understanding nuclear proliferation in that it focuses on the deeply misunderstood relationship between the two potential uses of nuclear power: energy and weapons. According to this theory, the civilian applications of nuclear technology cannot be separated from the potential military applications and vice versa. Ambivalence, therefore, extends into the realm of states’ nuclear intentions, making it impossible to know with certainty what a potential proliferator's “true” intentions are. This article will demonstrate that the concept of nuclear ambivalence applies in the case of Iran, suggesting that current international nonproliferation efforts run the risk of encouraging rather than discouraging Iranian weaponization. The final section outlines recommendations for policy makers to reverse this counterproductive nonproliferation approach.  相似文献

Introduction     
ABSTRACT

The new nuclear history can make a critical contribution by forcing us to reconsider or reframe the theoretical premises of the concepts we apply to our understanding of the present – and with which we try to navigate the future. It bears on fundamental questions, such as: How should the US manage its alliances? Should it establish a multilateral nuclear policy dialogue in Asia? In what depth should it discuss issues of doctrine and targeting with its Asian allies? What capabilities might reassure European allies in light of current Russian revisionism? Could nuclear war be limited and controlled in an East Asian maritime arena? Do nuclear weapons strengthen an alliance, or do they introduce a divisive bone of contention? Is extended nuclear deterrence (END) stabilizing or is it on the contrary pushing the allies to ask for more? What is the relationship between nuclear and conventional forces in END credibility? How do nuclear alliances contribute to international security and international order? The lessons and insights from these papers, which look at five historical cases of US extended deterrence during the Cold War, should help us think about crucial current issues, and be of use both to historians who want to have a better understanding of the Cold War past and to policymakers who are currently grappling with these issues.  相似文献

Russian reliance on its non-strategic nuclear arsenal has been an ongoing concern for security experts. What is the Russian de facto employment doctrine for this arsenal? This article argues that Russian non-strategic nuclear weapons (NSNW) have no defined mission and no deterrence framework has been elaborated for them. This study disentangles Russian thoughts and deeds about regional nuclear deterrence and the role of NSNW in it. Situating the Russian case in the comparative context, the article argues that establishing a coherent theater nuclear posture and streamlining it with the national level deterrence strategy is a demanding and frequently unfulfilled task. It is likely to remain as such for both current and prospective nuclear states that consider an asymmetrical deterrence posture.  相似文献

The authors propose five principles for addressing the major deficiencies of the current treaty-based approach to nonproliferation. These involve: effectively closing the door to withdrawals from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT); defining which nuclear technologies fall within the NPT's “inalienable right” provision, so as to maintain a reasonable safety margin against possible military application; expansion of International Atomic Energy Agency inspections to include greater readiness to use its “special” inspection authority; creation of an NPT enforcement regime, to include a secretariat; and universalizing the NPT so as to apply to all states, while creating a path for current non-parties to come into compliance. There is no illusion here about the prospects for the adoption of this approach. At a minimum, the world needs to be frank about the gap between nuclear programs and current nonproliferation protection. Encouragement of greater use of nuclear power should be predicated on closing that gap.  相似文献

ABSTRACT

There have been calls for the abolition of nuclear weapons from the day they were invented. Over the last fifteen years, some indications can be found that such calls have been getting louder, among them Barack Obama's famous 2009 speech in Prague. In this article, we investigate if support for a comprehensive norm that would prohibit development, possession, and use of nuclear weapons is really growing. To assess the current status of that norm, we use the model of a “norm life cycle,” developed by Martha Finnemore and Kathryn Sikkink. We then analyze 6,545 diplomatic statements from the review process of the Treaty on the Non-Proliferation of Nuclear Weapons as well as from the UN General Assembly First Committee on Disarmament and International Security, covering the years 2000 to 2013. The evidence shows that a comprehensive prohibition can be considered an emerging international norm that finds growing support among states without nuclear weapons and nuclear weapon states alike. Only a core group of states invoke the norm consistently, however. This leads us to conclude that the “tipping point” of the life cycle, at which adherence to a new norm starts to spread rapidly, has yet to be reached.  相似文献

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

The nuclear weapon states (NWS) have different perspectives on the desirability and feasibility of a world without nuclear weapons. A review of each of the current nuclear doctrines, postures, and disarmament policies of the five NWS shows that there is a clear divide between them, with some showing relatively determined leadership (the United States and the United Kingdom) and others expressing skepticism, if not complete disinterest (France, Russia, and China). Nevertheless, the prospects for progress on disarmament by the NWS at the 2010 Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons remain reasonably good. Yet complete success will require much time as well as sustained and applied efforts from the NWS, first and foremost to improve their performance as international security guarantors.  相似文献

This article questions the predominantly pessimistic assessments over the future of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). After analysing available evidence on states’ interests and interactions within the NPT’s framework, it argues that several negative expectations are unwarranted. Conversely, the article identifies three potentially threatening scenarios. Therefore, it scrutinizes the likely impact of reactive nuclear proliferation; analyses the probability of significant actors challenging the existent nuclear architecture; and explores whether the treaty’s enforcement might soon be diluted. The article concludes the NPT is unlikely to face fundamental threats in the foreseeable future.  相似文献

EDITOR'S NOTE     
The Nonproliferation Review (NPR) recently interviewed Ambassador Sergio de Queiroz Duarte of Brazil, who presided over the 2005 Seventh Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Ambassador Duarte discussed his views on the outcome of the conference and the future of the treaty. He provided NPR with valuable insights into the outcome of the conference and also shared his thoughts on some of the most pressing issues confronting the NPT today, including the Middle East, nuclear terrorism, elimination of the threat of highly enriched uranium in the civilian nuclear sector, proposals to limit access to the nuclear fuel cycle, nuclear disarmament, and negative security assurances. Blaming the failed conference on a general lack of political commitment among states parties and their unwillingness to negotiate common solutions, Ambassador Duarte stressed that “the conference should face squarely its own failure without my attempting to disguise or sugarcoat the deep differences of view, which must be resolved with courage and determination by the states parties if they want the treaty to remain effective.”?He emphasized that if states fail to act on their overriding interest in upholding the NPT, especially if states parties continue to ignore or disregard their nonproliferation and nuclear disarmament obligations, some states might come to believe that their security interests are no longer served by the treaty. The future prospects of the NPT would then “look dire indeed.”  相似文献

Current U.S. nuclear weapons strategy, force structure, and doctrine contribute to the threat of nuclear terrorism in several ways. First, the U.S. nuclear stockpile presents opportunities for nuclear terrorists to seize the materials they need. Second, U.S. nuclear forces remain a key justification for Russia's maintenance of similar nuclear forces that are less well protected. Third, America's continued embrace of nuclear weapons encourages and legitimizes other states to seek nuclear weapons that they will have difficulty securing from terrorists. The national security interests of the United States would be better served by a strategy to shrink the global footprint of nuclear weapons and provide the highest possible levels of security for the most minimal possible deterrent forces. Given the inability to secure nuclear weapons and materials perfectly or to eliminate terrorism in the foreseeable future, reducing the global inventory of nuclear weapons and materials is the most reliable way to reduce the chances of nuclear terrorism.  相似文献

NUCLEAR ISLANDS     
Current International Atomic Energy Agency safeguards do not provide adequate protection against the diversion to military use of materials or technology from certain types of sensitive nuclear fuel cycle facilities. In view of highly enriched uranium's relatively greater ease of use as a nuclear explosive material than plutonium and the significant diseconomies of commercial spent fuel reprocessing, this article focuses on the need for improved international controls over uranium enrichment facilities as the proximate justification for creation of an International Nuclear Fuel Cycle Association (INFCA). In principle, the proposal is equally applicable to alleviating the proliferation concerns provoked by nuclear fuel reprocessing plants and other sensitive nuclear fuel cycle facilities. The INFCA would provide significantly increased nonproliferation assurance to its member states and the wider international community by holding long-term leasehold contracts to operate secure restricted zones containing such sensitive nuclear facilities.  相似文献

Becoming a nuclear weapon state and sustaining a militarily credible nuclear weapons capability is far from trivial, especially for medium powers. Such a capability is demonstrated by much more than firing a first test or acquiring significant quantities of fissile material; capability is indicated by factors including weaponization, delivery of weapons, reliability and effectiveness of weapons and their delivery systems, fissile material availability, and nuclear and non-nuclear testing. Files in the British National Archives shed considerable light on the problems faced by the nuclear weapon program of the United Kingdom from 1952 through the late 1960s. The question is whether this experience is unique or if it instead offers insights into the potential problems faced by, or facing, other medium or aspiring nuclear weapon states. The proliferation-related topics highlighted include: fissile material production, nuclear testing, the first weapon, weapon delivery rates, non-nuclear testing, delivery platform problems, and long-term maintenance and capability sustainability. Further research could provide clearer insights.  相似文献

Nuclear energy is an integral part of China's energy strategy and will increasingly contribute to China's total energy supply. China has more than twenty civilian facilities, including power reactors, mines, and enrichment plants, to support its nuclear power program. As China operates more nuclear plants, more nuclear materials will be produced and stockpiled, and more nuclear facilities will be spread around the country. To ensure that this expanded network of nuclear facilities does not increase the risk that nuclear materials will be diverted or become the target of attack, China will need to develop more reliable domestic nuclear security strategies. China is also poised to become a major exporter of nuclear energy technology. China has committed to keeping nuclear technologies out of the hands of dangerous states and/or sub-state organizations, but in order to fulfill its nonproliferation obligations as well as its treaty-based commitment to share nuclear technologies, China will need to strengthen nuclear export controls and practices. This report examines and evaluates security measures at Chinese civilian nuclear power plants and suggests ways to improve them. It also reviews current export control policies and systems, identifies likely challenges to the expanding nuclear sector, and proposes possible solutions.  相似文献

In two landmark articles, longtime scholars Kenneth N. Waltz and Thomas C. Schelling have re-emphasized the utility of nuclear deterrence over nuclear nonproliferation (Waltz) and nuclear disarmament (Schelling). While the thrust of the articles is seemingly different, both are rooted in the same intellectual ground: an epistemology that assumes problem-free inferences, drawn from past experiences, are applicable in future scenarios; a foundational rooting in strategic rationality that entangles them in unsolvable contradictions concerning comparable risks of different nuclear constellations, namely deterrence versus proliferation and disarmament; and a bias in framing the empirical record that makes nuclear deterrence more conducive to security than nuclear disarmament. The common normative-practical denominator, then, is to let a nuclear weapon-free world appear both less desirable and less feasible than it might actually be.  相似文献

Cyberspace is a new domain of operation, with its own characteristics. Cyber weapons differ qualitatively from kinetic ones: They generate effects by non-kinetic means through information, technology, and networks. Their properties, opportunities, and constraints are comparable to the qualitative difference between conventional and nuclear weapons. New weapons and their target sets in a new domain raise a series of unresolved policy challenges at the domestic, bilateral, and international levels about deterrence, attribution, and response. They also introduce new risks: uncertainty about unintended consequences, expectations of efficacy, and uncertainty about both the target’s and the international community’s response. Cyber operations offer considerable benefits for states to achieve strategic objectives both covertly and overtly. However, without a strategic framework to contain and possibly deter their use, make state and non-state behavior more predictable in the absence of reciprocal norms, and limit their impact, an environment where states face persistent attacks that nonetheless fall below the threshold of armed conflict presents a policy dilemma that reinforces collective insecurity.  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

International Atomic Energy Agency (IAEA) safeguards are under more stress today than at any time in their history. Compliance concerns, a shortage of resources and technology, and growing responsibilities threaten to undermine the effectiveness and credibility of this vital and fundamental pillar of the nonproliferation regime. To address this challenge, the United States recently launched the Next Generation Safeguards Initiative. The goal of this initiative is to ensure the IAEA makes the fullest possible use of its existing authority to prevent the diversion of safeguarded material and to investigate suspicious activities. The initiative will advance state-of-the-art technology, foster the development of a new generation of safeguards experts, and promote technology collaborations and safeguards-conscious infrastructure in states using or pursuing nuclear power. Although it has a domestic focus, the initiative's intent is to catalyze a much broader commitment to international safeguards in partnership with other governments and the IAEA.  相似文献
