ABSTRACT

Recent nuclear-weapons-related consultation in NATO within the framework of the Defence and Deterrence Posture Review sheds light on historical experiences with nuclear consultation in NATO. In the early years of the Nuclear Planning Group (NPG), which became the main forum for multilateral nuclear consultation in the alliance, developing a nuclear weapons first use doctrine was of particular importance. This process led to the adoption of the Provisional Political Guidelines (PPGs) on the threat to initiate the use of nuclear weapons. With a focus on West Germany as the primary addressee of the NPG, it will be postulated that nuclear consultation functioned and may still be seen as an essential tool to manage the credibility of US extended nuclear deterrence in the framework of NATO.  相似文献

Stability among the great powers during the Cold War is widely theorized in terms of nuclear deterrence. Rationality of states and their preference for survival are the basis of nuclear deterrence. The rationality of non-state terrorist groups is different from that of nation-states. Even though they are also rational actors with their own hierarchy of preferences, survival may not be their ultimate goal. Deterrence of nuclear terrorism is therefore different from deterrence against states. South Asia is more vulnerable to nuclear terrorism than any other region of the world for many reasons. This article analyzes the possibility of nuclear terrorism and the ways of deterrence against it in the context of South Asia.  相似文献

Students of international politics known as ‘proliferation optimists’ argue that when it comes to the spread of nuclear weapons ‘more may be better’ because nuclear weapons deter great power war and produce greater levels of international stability. This essay provides a critique of proliferation optimism, challenging optimism’s conception of nuclear deterrence theory, its logical underpinnings, and its policy recommendations. It does this by conducting an intellectual history of proliferation optimism, identifying the core weaknesses of proliferation optimism as a theoretical framework, and articulating the myriad threats posed by nuclear proliferation.  相似文献

The years following the signature of the Nuclear Non-Proliferation Treaty (NPT) of 1968 have generally been seen as a period of neglect in US non-proliferation policy. While joining recent scholarship questioning this, the article also shows that the policies that emerged from the Nixon–Ford years were the product of a broad range of factors that constrained both the United States’ ability and willingness to build an effective non-proliferation regime. These included the Nixon administration’s initial skepticism regarding the NPT, as well as the global dispersion of power away from the US, combined with the continued importance of anti-Soviet containment.  相似文献

America’s alliances in Europe and East Asia all involve some institutional cooperation on U.S. nuclear weapons policy, planning or employment—from consultative fora in Asia to joint policy and sharing of nuclear warheads in NATO. Such cooperation is often analyzed through the prism of “extended nuclear deterrence,” which focuses on the extension of U.S. security guarantees and their effect on potential adversaries. This article argues that this underplays the importance of institutional factors: Allies have historically addressed a range of objectives through such cooperation, which has helped to catalyze agreements about broader alliance strategy. The varied form such cooperation takes in different alliances also flows from the respective bargaining power of allies and the relative importance of consensus, rather than perceived threats. The article concludes that nuclear weapons cooperation will remain crucial in successful U.S. alliance management, as allies negotiate their relationship with each other in the face of geostrategic change.  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

The funding of international nuclear risk mitigation is ad hoc, voluntary, and unpredictable, offering no transparent explanation of who is financially responsible for the task or why. Among many non-nuclear-armed states, this exacerbates a sense of injustice surrounding what they see as a discriminatory nuclear regime. The resulting erosion of the regime's legitimacy undermines support for efforts to prevent nuclear weapons dissemination and terrorism. This article proposes a transparent, equitable “nuclear-user-pays” system as a logical means of reversing this trend. This system envisions states contributing financially to international efforts to mitigate nuclear risks at a level relative to the degree of nuclear risks created by each state. “National nuclear risk factors” would be calculated by tabulating the risks associated with each state's civilian and military nuclear activities, as well as advanced dual-use and nuclear-capable missile activities, multiplying the severity of each risk by the probability of it occurring, and combining these results. A nuclear-user-pays model would create financial incentives for national and corporate nuclear risk mitigation, boost legitimacy and support for nuclear control efforts among non-nuclear-armed states, assist in preventing nuclear weapons dissemination and terrorism, and advance nuclear disarmament by helping progressively devalue nuclear weapons.  相似文献
