This commentary analyses the international response to the crisis that struck the Central African Republic (CAR) in early December 2013. It examines three intertwined dimensions defining the courses of action available to policymakers dealing with pre-genocidal crises: the politics and institutional manoeuvring shaping the United Nations (UN) Security Council's decision to authorise an enforcement mission without deploying ‘blue helmets’ on the ground; the operational complexities involved in launching rapid reaction forces; and the interdependent logics between peacebuilding and atrocity prevention. The author argues that there are three ways for the UN Secretariat to ensure a more effective response to CAR-type situations: generating political will to respond swiftly to deteriorating crises leading to widespread abuses of human rights by advancing the concept of Responsibility to Protect as a core component of states' national interests; developing strategic frameworks for the deployment of multi-plural missions equipped to avert the actual or potential threat of atrocities; and developing joint early warning and scenario planning between peacebuilding and atrocity prevention agencies.  相似文献

This article analyzes India's nuclear doctrine, finding it to be critically flawed and inimical to strategic stability in South Asia. In pursuing an ambitious triad of nuclear forces, India is straying from the sensible course it charted after going overtly nuclear in 1998. In doing so, it is exacerbating the triangular nuclear dilemma stemming from India's simultaneous rivalries with China and Pakistan. Strategic instability is compounded by India's pursuit of conventional “proactive strategy options,” which have the potential to lead to uncontrollable nuclear escalation on the subcontinent. New Delhi should reaffirm and redefine its doctrine of minimum credible nuclear deterrence, based on small nuclear forces with sufficient redundancy and diversity to deter a first strike by either China or Pakistan. It should also reinvigorate its nuclear diplomacy and assume a leadership role in the evolving global nuclear weapon regime.  相似文献

While recent history arguably demonstrates a high level of nuclear stability in South Asia, this article argues that this stability has historically been a function of India's relative weakness. It argues that, as India becomes stronger, attention must be paid to the technical and political requirements of nuclear stability: the reliability of weapons and command and control and the political conditions that underpin stable relations between nuclear-armed states. It concludes by recommending the United States aim to modify the perceptions of regional elites about their various intentions and decision-making processes and the role of the United States as crisis manager.  相似文献

The Indian nuclear program is a response to a perceived politico-strategic threat from China as opposed to a military-operational one that New Delhi began after perceiving an “ultimatum” from China in 1965. Consequently, India is in the process of acquiring an assured second-strike capability vis-à-vis China to meet the requirements of general deterrence. While India has always been concerned about the Sino-Pakistani nuclear/missile nexus, China has become wary of the growing military ties between the United States and India in recent years, especially because of the military implications of the US-India civil nuclear deal. Given the growing conventional military gap between the two states, India is not lowering its nuclear threshold to meet the Chinese conventional challenge. Instead, India is upgrading its conventional military strategy from dissuasion to deterrence against China. While the overall Sino-Indian nuclear relationship is stable, it will be challenged as China acquires advanced conventional weapons that blur the distinction between conventional and nuclear conflict.  相似文献

Australia's interest in nuclear weapons in the 1950s and 60s is usually explained in terms of high politics and grand strategy. This proliferation case study explores, in greater detail than hitherto, the important part played by the Royal Australian Air Force (RAAF) in pressing for a nuclear capability. It seeks to understand the reasons behind the RAAF's lobbying, in particular its previous experience with air power, its visceral desire for advanced manned bomber aircraft, and its strong institutional link to the British Royal Air Force. The decision in 1963 to acquire the supersonic US F-111 strike aircraft, instead of rivals including the British TSR.2, is also considered. Once the RAAF's bomber ambitions were satisfied, interest in nuclear weapons was greatly reduced. Finally, some comments are included on the nuclear interests of other air forces in the British Commonwealth.  相似文献

Sixteen years after stepping out of the nuclear closet, India's nuclear posture, some of its operational practices, and hardware developments are beginning to mimic those of the original five nuclear weapon states. Several proliferation scholars in the United States contend that India's national security managers are poised to repeat the worst mistakes of the superpowers’ Cold War nuclear competition, with negative consequences for deterrence, crisis, and stability in South Asia and the Asia-Pacific region. This article takes a contrarian view. It dissects the best available data to show why the alarmist view is overstated. It argues that not only are the alarmists’ claims unsupported by evidence, their interpretation of the skeletal and often contradictory data threatens to construct the very threat they prophesize.  相似文献

Approximately 470,000 refugees and migrants passed through Slovenian territory between September 2015 and March 2016, creating a crisis that required a great deal of organisational and field work on the part of many governmental and non-governmental institutions. In the social sciences, a discourse on “security versus humanitarian approach” on the refugees and migrant issue appeared; however, the article goes over such a discourse and deals with roles and problems of different institutions – mostly the military – that responded to the crisis. Namely, coping with the crisis was characterised by significant institutional adjustments, difficult co-ordination, and intense public debate. The Slovenian Armed Forces were included in this process as support for Civil Protection and Police. The military’s role followed the military missions defined by the Defence Act; however, the government also proposed some changes to the act that were met with some doubts on the part of the public and different institutions.  相似文献
