In nuclear nonproliferation negotiations, many governments pursue multiple objectives, and changes in policy can occur rapidly—and often unexpectedly. For these reasons, understanding nonproliferation requires empathy and imagination rather than just historical fact. This article considers one teaching tool to encourage such insight—simulations—and demonstrates how teaching and scholarship can interact to improve our understanding of the complex decisions and negotiations involved in nuclear nonproliferation. The article consists of five parts: first, it explains the benefits of simulations as both a policy development tool in Washington and as a teaching tool in universities; second, it describes the pedagogical strategy of the Stanford University simulation program; third, it shows how the simulations have identified and highlighted theoretical and substantive insights that are often neglected in scholarly studies of nonproliferation; and fourth, it describes how students are tested to enhance the learning experience from the simulation. Fifth and finally, the article provides concluding observations about how using simulations in the classroom can help scholars develop insights that improve their understanding of real-world nuclear negotiation dynamics and outcomes.  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

The policies toward countries aspiring to acquire nuclear weapons continue to be heavily contested, differing even among countries that consider nuclear proliferation as one of the main threats to international security. This article maps the actual policies of liberal democracies toward Iran and North Korea along a continuum from confrontation to accommodation. Using data from an expert survey, the authors outline four main findings. First, policies toward both Iran and North Korea have become increasingly confrontational over time. Second, no policy convergence was observed among the states studied; that is, notwithstanding the adoption of joint sanctions, differences remained between states preferring confrontation and those opting for accommodation. Third, states maintained remarkably stable policy profiles over time. Finally, despite obvious differences between the norm violations of North Korea and Iran, states generally followed remarkably similar policies toward both countries. The authors’ findings indicate that states exhibit stable preferences for either confrontation or accommodation toward nuclear aspirants. Although a comprehensive examination of the causes of these policy differences is beyond the scope of this article, the authors present evidence that a major cleavage exists between members and non-members of the Non-Aligned Movement, indicating that the degree to which nuclear aspirants’ sovereignty should be respected is a main issue of contention.  相似文献

In his 2009 Prague speech and the 2010 Nuclear Posture Review, President Barack Obama committed the United States to take concrete steps toward nuclear disarmament while maintaining a safe, secure, and effective nuclear deterrent. There is an inherent tension between these two goals that is best addressed through improved integration of nuclear weapons objectives with nuclear arms control objectives. This article reviews historical examples of the interaction between the two sets of objectives, develops a framework for analyzing opportunities for future integration, and suggests specific ideas that could benefit the nuclear weapons enterprise as it undergoes transformation and that could make the future enterprise compatible with a variety of arms control futures.  相似文献

Radioactive sealed sources have a long history and a much wider worldwide distribution than do weapons-usable fissile materials. This article compares the mechanisms for controlling radioactive sources with those of weapons-usable materials and makes the case for improved policy making on the safe and secure management of radioactive sources (often referred to simply as “sources”). Such sources have been widely distributed with commercial and government support to nearly every country, yet there are no legally binding, international agreements or regulations to control any aspect of their life cycle. This is problematic because some sources that are disused, abandoned, or otherwise fall out of regulatory control could be used in the form of a radiological dispersal device (RDD, or dirty bomb). An RDD could pose significant economic and psychological impacts with the potential for detrimental effects on public health. The lack of international measures to control sources is troubling for several reasons: creating an RDD is much easier than fashioning a nuclear weapon from scratch or from stolen fissile materials; given the many incidents involving diversion from regulatory control and the misuse of sources, an RDD attack would be one of the more likely scenarios; materials security for sources is generally weak and inconsistent; it is nearly impossible to determine the total amount of sources manufactured and distributed; used sources are frequently found uncontrolled and transiting borders, and penalties are light at best; the market-based supply and demand of sources facilitates their rapid and loosely regulated distribution; and the “peaceful uses” aspect of the Treaty on the Non-Proliferation of Nuclear Weapons along with norms that began developing around the time of Atoms for Peace have promoted the nearly unchecked global distribution of sources. Several immediate and long-term actions are suggested to reduce the threat posed by radiological sources.  相似文献

Between the 1960s and the 1990s, the US chemical industry went from lobbying against the Geneva Protocol and promoting increased funding for chemical warfare to refusing to produce binary chemical weapons and assisting with the negotiations of the Chemical Weapons Convention (CWC)—even though the treaty included provisions that could be costly to industry. What happened in those thirty years to make the US chemical industry reverse its position on chemical weapons? This article argues these changes were largely caused by the chemical industry's desire to reform the negative public image it had acquired due to its involvement in the Agent Orange scandal and other high-profile incidents during the 1970s and 1980s. The chemical industry's assistance with CWC negotiations may be explained after an examination of the US public policy literature, which argues that industry will support apparently costly regulations if doing so helps it repair a damaged public image and ensures greater profits in the long run.  相似文献

Despite the fact that Italy hosts almost half of the remaining estimated 150–200 US tactical nuclear weapons (TNW) that are currently deployed in Europe, case studies of Italy have been largely neglected. The article seeks to fill that gap by outlining the key elements of Italy's position regarding the presence, role, and future of TNW in Italy. By considering both the military and political-symbolic dimensions of TNW, the author argues that Italy has largely embraced the process of the devaluation of nuclear weapons; however, this is offset by the country's determination to preserve the principles of solidarity and the indivisibility of Euro-Atlantic security. By making the alliance's cohesion a priority, Italy appears willing to postpone the complete elimination of TNW from its territory if necessary; despite this, Italy otherwise considers TNW to be not only weapons of little intrinsic value but also obstacles to the global nuclear disarmament program that it strongly supports.  相似文献

Several years ago, Ward Wilson presented in this journal a wide-ranging challenge to what every generation of national security scholars and practitioners since the end of World War II has been taught about nuclear weapons. He asserted that nuclear deterrence amounts to far less than its proponents have claimed and provocatively suggested that nuclear deterrence is a myth. Relying upon both empirical and theoretical objections to nuclear deterrence, he concluded that its failures were clear-cut and indisputable, whereas its successes were speculative. Yet in spite of a flourishing trade in scholarly articles, think tank reports, blog posts, and opinion pieces concerning nuclear deterrence, nobody—including nuclear weapons scholars—has ventured more than a limited critique of Wilson's essay. There are, however, serious shortcomings in Wilson's arguments—deficiencies that make his essay an unpersuasive brief against nuclear deterrence. Wilson's thesis could be correct. His arguments, however, are unlikely to persuade any skeptical members of Congress, upon whom future progress in arms control depends, to reconsider the value they attach to nuclear weapons and nuclear deterrence.

The perpetuation of an otherwise astute fissile material safeguards model by the current non-proliferation regime raises a number of concerns, not least the efficacy of the approach in reducing clandestine weapon developments and the nuclear terrorism threat. Mindful of potential shifts in illicit nuclear material and weapon acquisition, following an excessive focus on fissile material safeguards and the proliferation of nuclear weapon technology, this article uses proliferation trend and scenario analysis in a bid to identify potential proliferation threats and non-proliferation opportunities. The results of the article's assessment of reported incidents (1992–2013) involving theft, unauthorised possession, and attempts to smuggle or sell highly enriched uranium (HEU), plutonium, low-enriched uranium (LEU), natural uranium and uranium yellowcake reveal a decline in occurrences involving fissile material but an increase in uranium yellowcake incidents, particularly in Africa. Presumptions that yellowcake may have provided the newest threat to clandestine weapon developments and nuclear terrorism wane amid concerns over possible biases in reporting, scepticism over an organised and demand-driven nuclear black market, and the difficulties of non-state actors’ development of crude nuclear weapons off the tedious yellowcake conversion-enrichment-fabrication pathway. To secure Africa's uranium yellowcake from potential proliferators, the article proposes concerted domestic, regional and multilateral non-proliferation efforts.  相似文献
