ABSTRACT

The present international standard allows non-nuclear weapon states (NNWS) to forego safeguards when nuclear material is used in a “non-proscribed military activity,” though no criteria have been established to determine when NNWS can remove naval nuclear material from safeguards. Though at present, only nuclear-armed states possess nuclear submarines, the global nuclear naval landscape may soon change with the advancement of Brazil's fledgling program and the possible precedent it would set for other NNWS. A framework is needed to shore up nuclear security and prevent nuclear material diversion from the nuclear naval sector. Proposed and existing nonproliferation frameworks, including a Fissile Material Cut-off Treaty and commitments through the nuclear security summits, are insufficient to close this loophole. A Naval Use Safeguards Agreement (NUSA), modeled after the Additional Protocol of the International Atomic Energy Agency, would provide a framework to remove the opacity surrounding nuclear material in the naval sector. Designed for NNWS and encouraged as confidence-building measures for nuclear weapon states, NUSA would explicitly outline those stages in the naval nuclear fuel cycle where safeguards are to be applied and in what context. This viewpoint also further provides direction for targeted research and development in technical naval nuclear safeguards solutions.  相似文献

In February 2012, Iran announced its willingness to resume negotiations with the Western powers. This statement followed in the wake of a damning report by the International Atomic Energy Agency (IAEA) Board of Governors and the imposition of additional sanctions by the international community on an Iranian economy already under pressure. Tehran's announcement also coincided with increased speculation regarding an Israeli military strike on Iranian nuclear facilities. At the same time, however, this seemingly positive step appeared to be undermined by Iran's concomitant announcement that “huge” technical progress has been made on Iran's nuclear programme. This article will explore the significance of the recent political, diplomatic and technical developments in the Iranian nuclear affair and situate them in the broader context of Tehran's nuclear strategy. The analysis will assess the potential for this latest phase in the Iranian nuclear crisis to reverse Iran's current trajectory and initiate a rapprochement between Iran and Western powers.  相似文献

ABSTRACT

The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) allows states to exempt nuclear material from international safeguards for use in nuclear submarine programs. This material, however, could be diverted for nuclear weapons purposes without the knowledge of inspectors, creating a potentially dangerous loophole in the treaty. This article argues that exercising that loophole today would amount to admitting a nuclear weapon program, making it a particularly poor pathway to a weapon for a potential proliferant. Still, if states like Brazil ultimately exempt nuclear material from safeguards for a nuclear submarine effort, they could set a dangerous precedent that makes it easier for others to use the loophole as a route to a nuclear weapon capability. There are several policy options available to mitigate the damage of such a precedent; most promising is the prospect of a voluntary safeguards arrangement that would allow international inspectors to keep an eye on nuclear material even after it has been dedicated to a naval nuclear propulsion program.  相似文献

ABSTRACT

Since the end of the Cold War, arms control proponents tried to make the case for deep nuclear reductions and other forms of security cooperation as necessary for strategic stability. While different versions of strategic stability analysis did sometimes produce innovative proposals, constructive negotiations, and successful ratification campaigns in the past, this analytical framework has become more of a hindrance than a help. Treating arms control as a predominantly technical way to make deterrence more stable by changing force structure characteristics, military operations, relative numbers of weapons on either side, or total number of nuclear weapons gives short shrift to political factors, including the fundamental assumptions about world politics that inform different arms control logics, the quality of political relations among leading states, and the political processes that affect negotiation, ratification, and implementation. This article compares two logics for arms control as a means to enhance strategic stability, one developed by the Cambridge community in the 1960s and one used by the Reagan administration and its successors, with current perspectives on strategic stability in which flexibility and freedom of action are preferable to predictability and arms control. It also contrasts what the Barack Obama administration has tried to achieve through strategic stability dialogues with Russia and China with how they envision security cooperation. It then presents an approach developed during the Cold War by Hedley Bull for thinking about both the technical and the political dimensions of arms control, and suggests that the logic of Cooperative Security (which shares important features with Bull's approach) is a more appropriate and productive way to think about arms control in the twenty-first century than strategic stability analysis is.  相似文献

ABSTRACT

Nuclear assets are one of the cornerstones of credible collective deterrence of the North Atlantic Treaty Organisation. Paradoxically, the most endangered member states are the ones without nuclear capabilities, left with the hope and expectation that the owners of nuclear assets will defend them and that their potential enemies are deterred by these capabilities. However, the expectations from one side, practical commitment of allies from other side may not go in harmony and synchronisation. Is there a capability gap which needs to be fulfilled? If yes then, is the gap in the side of nuclear powers or is it on the side of those endangered states who need to understand what can or cannot realistically be expected? The current article focuses on the question of how the political and military elite of the Baltic states describes their expectations in terms of using Alliance's nuclear capabilities to deter Russia's regional ambitions.  相似文献

ABSTRACT

Russian political leaders and military strategists are growing increasingly concerned about “strategic conventional weapons”—a broad category that appears to include all non-nuclear, high-precision, standoff weapons—and about long-range, hypersonic weapons, in particular. These concerns are complex and multifaceted (and, in some cases, contradictory), but chief among them are the beliefs that strategic conventional weapons could prove decisive in a major conflict and that Russia is lagging behind in their development. US programs to develop and acquire such weapons—namely, the Conventional Prompt Global Strike program—are of great concern to Russian strategists, who argue both that the United States seeks such weapons for potential use against Russia—its nuclear forces, in particular—and because strategic conventional weapons are more “usable” than nuclear weapons. Asymmetric responses by Russia include increased reliance on tactical nuclear weapons, efforts to enhance the survivability of its nuclear forces, and investments in air and missile defenses. There is also strong—but not completely conclusive evidence—that Russia is responding symmetrically by attempting to develop a long-range, conventionally armed boost-glide weapon.  相似文献

The Indian government has not made a public comment about the status of its nuclear weapon program since approving a nuclear doctrine in 2003. However, there is now enough information in the public domain to determine that the command-and-control system for the nuclear program has steadily matured in accordance with the intent of the approved nuclear doctrine. The Indian government has successfully mitigated many of the issues that plague the conventional military. The result is a basic command-and-control system that is focused only on the delivery, if ordered by the prime minister, of nuclear weapons. The system is not as robust as those of the United States and Russia, but is in place and ready as new Indian nuclear weapons enter into operation. The command-and-control system is developing to meet India's needs and political compulsions, but not necessarily as part of a more assertive nuclear policy.  相似文献

This article analyzes why US leaders did not use nuclear weapons during the Vietnam War. To date, there has been no systematic study of US decision-making on nuclear weapons during this war. This article offers an initial analysis, focusing on the Johnson and Nixon administrations. Although US leaders did not come close to using nuclear weapons in the conflict, nuclear options received more attention than has previously been appreciated. Johnson's advisers raised the issue of nuclear weapons and threats on several occasions, and Henry Kissinger, Nixon's national security adviser, looked into nuclear options to bring the war to an end. Ultimately, however, both administrations privately rejected such options. The conventional explanation for the non-use of nuclear weapons during the Cold War – deterrence – is insufficient to explain the Vietnam case. This article analyzes the role of military, political and normative considerations in restraining US use of nuclear weapons in the Vietnam War. It argues that while military and political considerations, including escalation concerns, are part of the explanation, a taboo against the use of nuclear weapons played a critical role.  相似文献

In 2003, the “E3”—Germany, France, and the United Kingdom—engaged Iran in talks over Tehran's nuclear program and were joined in negotiations the next year by the European Union (EU). Given the dim prospects of success for these talks, why did the E3/EU pursue nuclear negotiations with Iran? This article's three-track analysis attempts to answer that question by examining the emergence of the EU nonproliferation policy prior to the E3/EU-Iran talks, analyzing the European-Iranian relationship as it pertains to cooperation and negotiations over nonproliferation and other issues, and considering contemporary influences on the E3/EU. The European Union was ultimately unsuccessful in its negotiations with Tehran, but its efforts were worthwhile. In the future, the organization can play a vital nonproliferation role; today, the circumstances that hampered previous European efforts to resolve the Iranian nuclear standoff have improved and could be capitalized on by the European Union and the international community.  相似文献

ABSTRACT

South Africa's nuclear disarmament is a unique historical case, notable in part for the dramatic shift from deception to cooperation. The unprecedented transparency it demonstrated in order to convince the international community of the veracity of their disarmament is heralded as an exemplar for verifiable denuclearization. Less known is how this case affords insights into how a nuclear weapon program can be clandestinely hidden by the ambiguity provided by an otherwise completely legitimate, peaceful, nuclear energy program. Using a variety of open sources, including newly declassified internal South African and US government reports, it can be shown that South Africa employed a variety of deceptive tactics before it disarmed, and even for nearly two years after becoming a signatory to the Treaty on the Non-Proliferation of Nuclear Weapons. This article reviews that information to derive instructive lessons on the lengths that a nuclear proliferant state might go to conceal its true capabilities and intentions, and to thwart international discovery of the existence and full extent of an existing—or, in this case, a former—nuclear weapon program.  相似文献

Cyprus, a small island state, gained independence from British colonial rule in 1960. For more that half its history as an independent state Cyprus has been under occupation following the 1974 Turkish invasion. Despite the fact that it has faced war, invasion and occupation, Cyprus has allocated a comparatively small proportion of its national income to defence. The average defence burden—military expenditure as a share of GDP—during 1964–98 was around 2.5%. However, as a result of a substantial shift in defence policy during the past decade or so, the defence burden during the 1990s has increased, averaging about 4% of GDP as Cyprus decided to implement an extensive military modernization program aiming to present a more credible military deterrence vis‐a‐vis Turkey. Empirical estimations of a demand function for Cypriot military expenditure suggest that it is positively affected by alliance spillins and external military threat.  相似文献

ABSTRACT

Since the 1950s, the United States has engaged in nuclear sharing with its NATO allies. Today, 150-200 tactical nuclear weapons remain on European soil. However, the Treaty on the Non-proliferation of Nuclear Weapons (NPT) prohibits the transfer of nuclear weapons to non-nuclear weapon states. The potential discrepancy between text and practice raises the question of how the NPT's negotiators dealt with NATO's nuclear-sharing arrangements while drafting the treaty that would eventually become the bedrock of the international nonproliferation regime. Using a multitiered analysis of secret negotiations within the White House National Security Council, NATO, and US-Soviet bilateral meetings, this article finds that NATO's nuclear-sharing arrangements strengthened the NPT in the short term by lowering West German incentives to build the bomb. However, this article also finds that decision makers and negotiators in the Lyndon B. Johnson administration had a coordinated strategy of deliberately inserting ambiguous language into drafts of Articles I and II of the Treaty to protect and preserve NATO's pre-existing nuclear-sharing arrangements in Europe. This diplomatic approach by the Johnson administration offers lessons for challenges concerning NATO and relations with Russia today.  相似文献

ABSTRACT

In No Use: Nuclear Weapons and U.S. National Security Policy, Thomas M. Nichols calls for a constructive rethinking about the history of nuclear weapons and the attitudes that have grown up around them. Despite dramatic reductions since the end of the Cold War, the United States still maintains a robust nuclear triad that far exceeds the needs of realistic deterrence in the twenty-first century. Nichols advocates a new strategy of minimum deterrence that includes deep unilateral reductions to the US nuclear arsenal, a no-first-use pledge, withdrawing US tactical nuclear weapons from Europe, and ending extended nuclear deterrence for allies. The weakest part of his argument eschews nuclear retaliation against small nuclear states that attack the United States, opting instead to use only conventional weapons to guarantee regime change. He admits this will entail enormous cost and sacrifice, but cites the “immorality” of retaliating against a smaller power with few targets worthy of nuclear weaponry, which totally ignores the massive underground facilities constructed to shield military facilities in many of these states. Despite this, Nichols's thoughtful approach to post-Cold War deterrence deserves thoughtful consideration.  相似文献

ABSTRACT

The India–Pakistan near war of February–March 2019 highlights India’s ongoing evolution in strategic thought and practice since its emergence in 1998 as an overt nuclear-weapon possessor. These changes, involving an increasing willingness to engage in the intentional escalation of conflict with a nuclear-armed rival willing to be the first to use nuclear weapons, challenge certain academic assumptions about the behavior of nuclear-weapon states. In particular, they undermine the expectations of the nuclear-revolution theory—which anticipates nuclear and conventional restraint among nuclear-armed rivals through fear of mutual assured destruction—and the model of nuclear learning which underpins this theory, in which new nuclear-weapon states gradually absorb this restraint through policy-maker learning. This article explores how India’s learning pathway since 1998 has deviated from these expectations. India is instead pursuing its own “revolution,” in the direction of creating capabilities for flexible response and escalation dominance. It concludes by illuminating the similarities between Indian strategic behavior and contemporary practices of other nuclear-armed states, and suggests that New Delhi’s emerging de facto nuclear doctrine and posture is part of a broader empirical challenge to our current conceptions of the nuclear revolution and of nuclear learning.  相似文献

Thanks to its geographical location and close military ties to the US and Britain, Norway took substantial part in the Western intelligence effort against the Soviet nuclear weapons programme during the Cold War. Norway's relative proximity to the nuclear weapons test sites on Novaya Zemlya and the nuclear submarine bases on the Kola Peninsula was of particular importance in this regard. Whereas the tasks of surveying the development, deployment and possible employment of Soviet nuclear forces always had first priority, Western atomic intelligence conducted from Norwegian soil and waters was occasionally aimed even at gathering information about the geophysical and possible long-term medical and environmental implications of high-yield nuclear explosions in the atmosphere.  相似文献

The ultimate goal of Iran's nuclear programme remains uncertain. While the nuclear reactor of Bushehr has finally been connected to the power grid, the nuclear fuel enrichment activities and their location cause concern to the international community. Thirty years of nuclear investments demonstrate a negative cost–benefit analysis: technical constraints and economic and infrastructural requirements constitute a burden on the implementation of a nuclear programme. This article analyses the economic, legal, technical and political aspects of the Iranian programme in order to uncover its civil and/or military finality.  相似文献

Abstract

How did the Israel Defense Forces' (IDF) organisational and military culture shape their understanding of security threats, perceptions of warfare, and instinctive responses to security challenges? Israel's early military history is marked by the stubborn persistence of accepted patterns of thought and action. In the first twenty years of its existence, the IDF habitually came to sacrifice both political and military long-term and medium-term considerations in favour of the superficial, short-term satisfaction of its drive for action. The Israeli Army as an institution separated military actions from their political implications, and all too often, granted itself freedom of action at all levels of command. That myopic pattern led to recurring raids and minor operations during the 1950s, and contributed notably to the outbreak of the Six-Day War in 1967.  相似文献

ABSTRACT

In 2019, the geostrategic landscape of South Asia significantly changed. A crisis between India and Pakistan involved air strikes across international boundaries for the first time since the 1971 war. Pakistan came close to economic collapse, while India re-elected hawkish Narendra Modi as prime minister in a landslide. These developments, alongside the United States’ efforts to strike a deal to leave Afghanistan and rapidly improving US-India relations, portend new challenges for Pakistan’s security managers—challenges that nuclear weapons are ill-suited to address. Despite the shifting security and political situation in the region, however, Pakistan’s nuclear posture and doctrine seem unlikely to change. This article explores the roots of Pakistan’s reliance on the traditional predictions of the nuclear revolution, most notably the notion that nuclear-armed states will not go to war with one another, and argues that this reliance on nuclear deterrence is a response both to Pakistan’s security environment and to serious constraints on moving away from nuclear weapons toward an improved conventional force posture. Pakistan’s central problems remain the same as when it first contemplated nuclear weapons: the threat from India, the absence of true allies, a weak state and a weaker economy, and few friends in the international system. While 2019 may have been a turning point for other states in the region, Pakistan is likely to stay the course.  相似文献

ABSTRACT

Over the last five decades, India’s nuclear and space programs have gone through several phases, from collaboration to divorce to supportive. An interplay of two factors determined the nature of the relationship. One was the state of India’s nuclear-weapon program. The second was international conditions, especially India’s relationship with the nuclear-nonproliferation regime. In the early decades, because of the rudimentary nature of India’s nuclear and space programs, the relationship was collaborative, since the rocket technology being developed was a necessary adjunct to the nuclear-weapon program. Subsequently, as India’s rocketry capabilities and nuclear-weapon program began to mature and concerns about international sanctions under the non-proliferation regime began to grow, the two programs were separated. The Indian rocketry program was also divided, with the civilian-space and ballistic-missile programs clearly demarcated. After India declared itself a nuclear-weapon state in 1998 and the programs matured, the relationship has become more supportive. As the two programs mature further, this relationship is likely to deepen, as the nuclear-weapon program requires space assets to build a robust and survivable nuclear deterrent force.  相似文献
