This article explores the potential impact of U.S. disarmament leadership on the nuclear diplomacy of North Korea and Iran, the “defiant states.” The first part of the article introduces the concept of “interaction capacity,” which measures a state's integration into international society, based on its physical communication systems and its adoption of shared norms. The theory predicts that lower levels of interaction capacity will generate a greater propensity for nuclear defiance, as the affected states reject and try to resist integration pressures. In the second and third parts of the article, this conceptual framework is applied to the cases of North Korea and Iran. The analysis suggests that efforts to reassert U.S. disarmament leadership could increase the alienation of North Korea and Iran, leading to provocation and escalation of nuclear tensions. The final part of the paper explores the policy implications of this analysis for the potentially defunct six-party talks, for hopes of renewed negotiations with Iran, and for the 2010 Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons. 相似文献

Infrared (IR) small target detection is one of the key technologies of infrared search and track (IRST) systems. Existing methods have some limitations in detection performance, especially when the target size is irregular or the background is complex. In this paper, we propose a pixel-level local contrast measure (PLLCM), which can subdivide small targets and backgrounds at pixel level simultaneously. With pixel-level segmentation, the difference between the target and the background becomes more obvious, which helps to improve the detection performance. First, we design a multiscale sliding window to quickly extract candidate target pixels. Then, a local window based on random walker (RW) is designed for pixel-level target segmentation. After that, PLLCM incorporating probability weights and scale constraints is proposed to accurately measure local contrast and suppress various types of background interference. Finally, an adaptive threshold operation is applied to separate the target from the PLLCM enhanced map. Experimental results show that the proposed method has a higher detection rate and a lower false alarm rate than the baseline algorithms, while achieving a high speed. 相似文献

Did participants in small wars in the period 1775–1831 learn from previous or contemporary examples? While this is difficult to prove for participants who left no written records, there is considerable evidence in existing publications by practitioners that they did indeed draw out lessons from recent insurgencies, either from their own experience or from events elsewhere which they studied from afar, especially the Spanish Guerrilla, which had already become legendary. Most authors showed an interest in how to stage insurgencies rather than in how to quell them. Even then, transfer did not come in a package of tactics-cum-values, but in each case in different configurations. 相似文献

What explains the pace at which militaries adopt new technology? We argue that the hierarchical structure and unique expertise requirements of military organizations combine to empower select individuals as ‘gatekeepers’ of innovation. These individuals acquire beliefs throughout their military careers regarding the nature and means of warfare that act to shape their attitudes towards new military innovations. By filtering, sidelining, and ignoring competing sources of advice and information, these officers actively inhibit the adoption of new, often advantageous, innovations. We develop this argument through the analysis of two cases: the delayed acquisition of breech-loading and repeating rifles by the Union Army during the American Civil War, and the failure of the US Army to adopt an adequate heavy-type tank in World War II. 相似文献

Vietnam was a complex conflict, which historians and political scientists have struggled to understand. Some of the bitterest disputes in the historiography revolve around the US approach to counterinsurgency in Vietnam. Many different facets of the war have received the attention of filmmakers, and an examination of their work suggests new ways of thinking about the conflict. This article considers film portrayals of three phases of the Vietnam War – firstly, the early period of ‘political action’, then the advisory period, and finally the Americanization of the war after 1965. It suggests that by examining the experiences of participants in each of these phases, Vietnam War cinema helps to illustrate the problems that faced various American approaches to counterinsurgency in the conflict. Combined with the importance of films in determining popular perceptions of both historical conflicts and counterinsurgency in general, it suggests that they are worthy subjects of study and critique. 相似文献

《孙子兵法》是我国古代流传下来的最早、最完整、最著名的军事著作,也是现存中国和世界军事理论史上最早形成体系的军事理论巨著。《孙子兵法》问世以来,对其军事理论价值和其语言文学价值的研究成果很多。但是,相对而言,对其语言研究还是比较薄弱的。从语音、词汇、语法、修辞、篇章结构五个方面进行分析和总结,有助于正确掌握和评价《孙子兵法》语言研究的现状和价值。 相似文献

Abstract In Western operations in Afghanistan, small European powers escalate in different ways. While Denmark and the Netherlands have contributed to Western escalation through integration with British and US forces, Norway and Sweden have done so by creating a division of labour allowing US and British combat forces to concentrate their efforts in the south. These variations in strategic behaviour suggest that the strategic choice of small powers is more diversified than usually assumed. We argue that strategic culture can explain the variation in strategic behaviour of the small allies in Afghanistan. In particular, Dutch and Danish internationalism have reconciled the use of force in the national and international domains, while in Sweden and Norway there is still a sharp distinction between national interest and humanitarianism. 相似文献

This article investigates how key actors within the US defence policy community realigned their interests to forge a new consensus on the redirection of US defence strategy following the ‘peace shock’ they faced with the collapse of bipolarity. This consensus centred on the idea that achieving US security in the ‘age of uncertainty’ demanded overwhelming US military power, which was widely interpreted as necessitating military capabilities to fight multiple major theatre wars simultaneously against regional ‘Third World’ adversaries. This helped to preserve many of the principal pillars of US Cold War defence policy through deflecting calls for more radical organisational changes and deeper cuts to defence budgets. 相似文献
