ABSTRACT

The recent use of chemicals in warfare in Syria and Iraq illustrates that, despite the important work of the 1997 Chemical Weapons Convention (CWC), the world has not yet been totally successful in stopping the use of indiscriminate toxic agents in conflicts, either by states or non-state actors. Michael Crowley's excellent and timely new book, Chemical Control, analyzes the use of “riot control agents” (RCAs) and “incapacitating chemical agents” (ICAs), including launch and dispersal systems, by police, paramilitary, and military forces over the last decades and raises the challenging question about where the red line might be drawn between banned and permitted uses of chemicals. He discusses this problem not only in the context of the CWC, which allows use of RCAs for civilian riot control, but also in the context of international law, human rights, and criminal justice, including the Biological and Toxin Weapons Convention and other disarmament and abolition regimes. He proposes a “holistic, three-stage approach” to addressing this issue “for effective regulation or prohibition of the weapon or weapon-related technology of concern.” As we approach the global abolition of a whole class of weapons of mass destruction in the next decade or even sooner, Chemical Control is helpful in better understanding and solving the dilemma of what's actually banned or permitted under international law, and precluding states undermining the chemical weapons ban.  相似文献

ABSTRACT

What restrains states from employing chemical weapons during modern war? Despite widespread and consistent efforts by the international community to outlaw chemical weapons in the twentieth century, major deviations from this goal occur. Two of the strongest explanations that exist for this trend are the logics of deterrence and norms that consider the use of chemical weapons to be a taboo. We test these theories using factor analysis and find that norms provide a better explanation of non-use in the twentieth century among states with a chemical-weapon capability. We then conclude with avenues for future research in this burgeoning field of study, which includes closer qualitative examination of norms, as well as the expansion of the dataset to include intrastate warfare and non-state warfare.  相似文献

As the United States and Russia contemplate the next stage of nuclear arms reductions beyond the 2010 New Strategic Arms Reduction Treaty, another issue enters the agenda—that of the impact of possible deep reductions on the shape of the global nuclear balance. As the gap between the US/Russian arsenals and the arsenals of “second-tier” nuclear weapon states narrows, the familiar shape of the global balance, which remains, to a large extent, bipolar, is likely to change. The article explores the Russian approach to the relationship between further US-Russian reductions and the prospect of “nuclear multipolarity,” and assesses the relative weight of this issue in Russian arms control policy as well as the views on the two specific regional balances—the one in Europe (including UK and French nuclear weapons) and in Asia (the possible dynamic of the Russian-Chinese nuclear balance).  相似文献

Chinese writings on the workings of nuclear stability, deterrence, and coercion are thin and politicized. Nevertheless, it is possible to glean, from direct and inferential evidence, rather pessimistic conclusions regarding Chinese views of nuclear stability at low numbers. While China has been living with low numbers in its own arsenal for decades, today it views missile defense and advanced conventional weapons as the primary threat to nuclear stability. More generally, China views nuclear stability as wedded to political amity. Because none of these would be directly addressed through further US and Russian arsenal reductions, China is unlikely to view such reductions as particularly stabilizing. While there is little in Chinese writing to suggest lower US and Russian numbers would encourage a “race to parity,” there are grounds to worry about China becoming more assertive as it gains confidence in Beijing's own increasingly secure second-strike forces.  相似文献

This article distills insights for the scholarship of deterrence by examining the 1983 nuclear crisis – the moment of maximum danger of the late Cold War. Important contributions notwithstanding, our understanding of this episode still has caveats, and a significant pool of theoretical lessons for strategic studies remain to be learned. Utilizing newly available sources, this article suggests an alternative interpretation of Soviet and US conduct. It argues that the then US deterrence strategy almost produced Soviet nuclear overreaction by nearly turning a NATO exercise into a prelude to a preventive Soviet attack. Building on historical findings, this article offers insights about a mechanism for deterrence effectiveness evaluation, recommends establishing a structure responsible for this endeavor, and introduces a new theoretical term to the strategic studies lexicon – a ‘culminating point of deterrence’.  相似文献

Drawing on evidence collected from eyewitness interviews, new Russian secondary sources, as well as recently declassified documents from both sides, the author significantly widens the academic understanding of the maritime dimension of this gravest crisis of the Cold War. Most significant is her conclusion that Soviet commanders were led by complex and challenging tactical circumstances, including unreliable communications and malfunctioning equipment, which might have prompted them to contemplate a resort to tactical nuclear weapons on more than one occasion. Almost as disturbing is the revelation that US forces were not aware of this particular threat. This research reveals how a chain of inadvertent developments at sea could have precipitated global nuclear war, underlining the extreme danger of the crisis.  相似文献

This article seeks to compare Australia's involvement in two key 1990s peace missions: those to Somalia in 1992–93 and Rwanda in 1994–95. While there are many similarities between the two missions in terms of time, scale and theatre, the differences are more important. Both missions are usually recalled as failures despite the Australian troops having been extremely successful in their roles during both deployments. Moreover the experiences with intervention in Africa seem to have forever blighted Australian participation in peace missions on that continent.  相似文献

长期以来,学生的情感发展被教育者所忽视。目前教育技术学学科定位仍处于争论阶段,而其自身较明显的技术外观又往往使专业学生对该学科的理解和认识产生不同程度的偏误。但需要明确的是,学生接受专业教育,既要学习认知层面的专业知识,更要明确以价值观为代表的专业情感目标。可以认为,忽视了专业情感目标的教学是畸形的教学。本文从罗杰斯人本主义理论的视角出发,分析了构建基于QQ群的情感目标教学环境的设计方案,旨在促进教育技术专业的健康发展。  相似文献
