从《中导条约》的失效看未来国际军控走向

《美苏消除两国中程导弹和中短程导弹条约》的失效重创了本就脆弱的国际军控体系,对美俄战略稳定和全球军事安全带来消极影响,国际军控合作和全球军事安全迫切需要重构新的军控体系。本文立足当前国际军控现状,在分析美俄“退约”背后各方战略考量及国际军控面临的挑战,如“美国优先”理念下的霸权主义和单边主义、国际军控体系自身的脆弱性和局限性和新军事革命给全球安全增添新的变量的基础上,提出了“构建人类命运共同体”理念凝聚全球安全共识、以大国责任和义务为基础构建多层次军控体系和以多边军控体系循序推进国际军控进程等措施和建议,以期为推动国际军控合作,建立更为公平、合理、有效的国际军控体系做出贡献。     

The politics of international chemical weapon justice: The case of Syria, 2011–2017

There has been near-universal condemnation of the use of chemical weapons in the Syrian conflict. The international community has nevertheless struggled to make progress on holding the perpetrators to account. This article reviews developments at the international level in terms of Syrian chemical weapon justice between 2011 and 2017. It argues that there have been substantive disagreements between states on the rationale and means of justice in the Syrian case. It also argues that international initiatives have been tightly intertwined with developments in chemical disarmament and conflict resolution processes as well as the broader war. The article describes progress and challenges to chemical weapon justice in a number of distinct formal international mechanisms during the period studied. The analysis concludes by contextualizing international responses—including the U.S. tomahawk strikes against a Syrian airbase—to the Khan Shaykhun chemical attacks of April 2017.     

野外复杂背景下轻武器射击目标的图像识别算法

针对野外复杂背景下轻武器射击目标图像的分析判别,首先采用一种彩色空间聚类分析和阈值分割相结合的混合算法,即基于S、I通道的目标图像两步分割算法,将目标区域从背景图像中分离出来.然后基于机器学习理论中的Boosting算法,利用区域的形状特征和纹理特征等组成一个强分类器,将目标区域从其他区域分离出来,同时判断出目标的类型.     

An evolving state of play? Exploring competitive advantages of state assets in proliferation networks

Illicit procurement networks often target industry in developed economies to acquire materials and components of use in WMD and military programs. These procurement networks are ultimately directed by elements of the proliferating state and utilize state resources to undertake their activities: diplomats and missions, state intelligence networks, and state-connected logistical assets. These state assets have also been utilized to facilitate the export of WMD and military technologies in breach of sanctions. While used in most historic proliferation cases, their role has seen limited consideration in the scholarly literature. This article seeks to systematically contextualize state resources in proliferation networks, arguing that their use lies between state criminality and routine activity in support of national security. Considering the competitive advantages of these assets compared to similar resources available in the private sector, the article argues that nonproliferation efforts have caused states to change how they use these resources through an ongoing process of competitive adaptation.     

Into the black box? Technology sharing in major arms transfers and beyond

From the recipients’ perspective, arms transfers have, through the use of offsets, technology transfers, and industrial participation, become an opportunity to receive not only advanced weapons, but also technologies not otherwise available. How important are friendly relations for securing a military export order? To what extent do buyers demand advanced military or commercial technology and how are these demands accepted by the supplier? How does this influence smaller producers in relation to major producers? These questions are addressed by studying (a) the Joint Strike Fighter/F-35 by Lockheed Martin, USA, and the JAS-39 Gripen aircraft by Saab, Sweden, (b) the Medium Multi-Role Combat Aircraft competition in India for 126 combat aircraft, and (c) the Indian offset policy. In the final section, some long-term consequences are discussed.     

The comparison of military budgets of the eastern and central European countries

The evolutions of military expenditures in Eastern and Central European countries are difficult to estimate and to compare, due to the lack of available data for these states. Some results of the extent of cuts in defence spending since 1990 are interesting to interpret, but it is difficult for econometricians to use these figures even carefully. The structures of national military expenditure have been modified to the detriment of arms equipment. Thus, the disarmament process needs a special analysis of the arms industry.     

AN ENDOGENOUS GROWTH MODEL OF CAPITAL AND ARMS ACCUMULATION

This paper attempts to examine the effect of an anticipated foreign military threat on the steady‐state growth rate and the transitional behavior of the economy. The modeling strategy follows the Sandler and Hartley (1995 Sandler, T. and Hartley, K. 1995. The Economics of Defense, Cambridge: Cambridge University Press.  [Google Scholar]) and Dunne et al. (2005 Dunne, J.P., Smith, R.P. and Willenbockel, D. 2005. Models of military expenditure and growth: a critical review. Defence and Peace Economics, 16: 449–461. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) viewpoints to emphasize the role of national defense in affecting growth from the perspective of both the demand and the supply sides. We thus combine the public capital version of endogenous growth with a framework of competitive arms accumulation. It is found that the key factor determining the steady state and the transitional effects of a rise in the foreign military threat on the home weapon–capital ratio, the consumption–capital ratio, and the rate of economic growth, is the degree of relative risk aversion.     

INTEGRATING NUCLEAR WEAPONS STOCKPILE MANAGEMENT AND NUCLEAR ARMS CONTROL OBJECTIVES TO ENABLE SIGNIFICANT STOCKPILE REDUCTIONS

In his 2009 Prague speech and the 2010 Nuclear Posture Review, President Barack Obama committed the United States to take concrete steps toward nuclear disarmament while maintaining a safe, secure, and effective nuclear deterrent. There is an inherent tension between these two goals that is best addressed through improved integration of nuclear weapons objectives with nuclear arms control objectives. This article reviews historical examples of the interaction between the two sets of objectives, develops a framework for analyzing opportunities for future integration, and suggests specific ideas that could benefit the nuclear weapons enterprise as it undergoes transformation and that could make the future enterprise compatible with a variety of arms control futures.     

ALTERNATIVE NARRATIVES FOR ARMS CONTROL

The efforts of President Barack Obama and his administration to restore the United States as a driving force of multilateral arms control and nonproliferation negotiations are commendable, yet the lack of progress on such issues over the last eight years has ensured that U.S. policy has not kept pace with changes in the geostrategic environment and the evolving security agenda. Meanwhile, an alternative agenda has been articulated by non-Western countries. This article focuses on the arms control perspectives of Non-Aligned Movement states and others that have begun to embrace the idea of “disarmament as humanitarian action.” It explores this idea in the context of recent initiatives and argues that if the Obama administration wants to make progress on its arms control and nonproliferation priorities, it should consider a multifaceted approach that incorporates this emerging alternative agenda.
