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

African states are hampered by unreliable electric energy that has not complemented economic development efforts. Recently, several African states announced plans to pursue nuclear energy in the future. However, several challenges remain for these states, notably insecurity and financial deficiencies. This paper proposes the use of regional integration arrangements to address these challenges faced by African states, as a way of complementing other efforts enabling African states to obtain nuclear energy. The existence of these arrangements and their institutional mechanisms can enable African states to enhance security and cost-effectively develop nuclear power infrastructure. 相似文献

With the exception of Iran, no Middle Eastern state has an operating nuclear power reactor. Several states, including the United Arab Emirates, Saudi Arabia, Qatar, Kuwait, Israel, Syria, Jordan, Turkey, and Egypt are considering constructing such reactors; some have even taken steps towards commencing nuclear power projects. There exist, however, considerable economic, technical, safety, and security challenges to achieving these goals, many of which are acute in the Middle East region. Regional and international cooperation on nuclear technology could not only help regional states meet their energy objectives, but it could also help to build trust among states as a basic step towards a future Middle East Weapons of Mass Destruction-Free Zone. 相似文献

Indonesia, Thailand, and Vietnam recently announced that they are launching nuclear energy programs, and Malaysia and the Philippines soon may follow suit. As a result, by 2020, at least three states in Southeast Asia could possess latent nuclear capabilities—the option to pursue military applications of dual-use nuclear technology. Analysis of the nuclear programs, domestic proliferation pressures, and the external threat environment in Southeast Asia leads the authors to conclude that the nuclear intentions of states in that region are entirely peaceful and the probability of future nuclear breakout there is low. However, this finding does not justify complacency. In the long term, the benign outlook for regional security may change, and in the near term weak regulatory regimes present serious challenges to nuclear safety and create opportunities that non-state actors may exploit. To minimize these risks, the authors recommend creating a “proliferation firewall” around the region, which would combine strong global support for Southeast Asian nuclear energy programs with innovative regional multilateral nuclear arrangements. 相似文献
