Putin – the masked nemesis of the strategy of ambiguity

Recent events demonstrate the complex and adaptive approach employed by Russia to reassert influence in Europe. The changing face of Russia’s strategy commenced in 2007 when it launched a crippling cyber-attack against Estonia. This was followed by a large Russian conventional attack against Georgia in 2008, occupying two large areas of the nation. 2014 witnessed the Russian annexation of Crimea where in just a week, Russia seized control of Crimea “without firing a shot.” The annexation of Crimea was rapidly followed by a Russian inspired and led subversive war in eastern Ukraine. The common thread among these diverse Russian operations is its use of ambiguity to confound and confuse decision makers in the West.     

India's counter-insurgency experience: the ‘trust and nurture’ strategy

The Indian Army, a force trained primarily for conventional warfare, has been engaged in internal counter-insurgency operations since the 1950s. Despite such a long innings on a counter-insurgency mode, little attention has been accorded within military circles to doctrinal innovation for waging sub-conventional warfare in India's democratic political context. At best, the Army continues to view counter-insurgency duty as secondary to its primary duty of defending India from external conventional threats. By conceptualizing a counter-insurgency strategy of ‘trust and nurture’, this article aims to fill this critical doctrinal gap in India's military policy. The author argues that a counter-insurgency strategy of ‘trust and nurture’ based on democratic political culture, measured military methods, special counter-insurgency forces, local social and cultural awareness and an integrative nation-building approach will result in positive handling of India's internal security problems. The author utilizes India's counter-insurgency experiences in Assam, Mizoram, Nagaland, Punjab, and Operation ‘Sadhbhavana’ in Jammu and Kashmir as illustrative empirical indicants in order to validate the ‘trust and nurture’ strategy.

The practice and theory of British counterinsurgency: the histories of the atrocities at the Palestinian villages of al-Bassa and Halhul, 1938–1939

This article details two largely unreported atrocities by British forces operating against Arab rebels during the Arab revolt, 1936–9, at the Palestinian villages of al-Bassa and Halhul. It then examines the military-legal system that underpinned and authorised British military forces operating in aid of the civil power, suggesting that the law in place at the time allowed for a level of reprisals and punitive actions, such as happened at al-Bassa and Halhul. The article does not conclude that the law allowed for atrocities but it does argue that it gave a basic form and understanding to an operational method that was brutal and could lead to atrocities. It thus tests the idea in much of the literature on counterinsurgency that the British were restrained and used minimum force when compared to other colonial and neo-colonial powers fighting insurgents.     

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.     

A Muslim by any other name

Abstract

A crisis is emerging in the Nile Basin, where some 300 million people in Egypt, Sudan, Ethiopia, Uganda, the Democratic Republic of Congo, Rwanda, Kenya, Tanzania and Burundi rely on the Nile directly or indirectly. Egypt and Sudan wish to preserve a regime based on treaties drawn up during the colonial era that allocated the vast majority of the Nile's water to them. Countries upstream are determined to challenge this. In 1999 the countries using the river formed the Nile Basin Initiative to try to resolve these differences. More than a decade of negotiations failed to break the impasse. In May Ethiopia, Kenya, Rwanda, Tanzania and Uganda decided to wait no longer and signed a new treaty, without the consent of Egypt and Sudan. The signatories have given the other Nile Basin countries one year to join the pact. For Egypt, which relies on the Nile for 95 per cent of its water, this is a question of life or death. Egypt has, in the past, indicated it will go to war if its share of the Nile is reduced. Talks continue, but the impasse is driving the region towards a crisis to which there is no easy resolution.     

爆炸冲击波对靶板的损伤仿真与评估研究

为了研究爆炸冲击波对武器装备的损伤，建立了炸药爆炸冲击靶板的有限元模型，对不同厚度靶板在确定爆炸冲击环境下的损伤进行了仿真试验。不同于传统的宏观破口尺寸损伤表征参数，引入了等效塑性应变来精确描述靶板损伤，并提出了一种基于主成分分析理论对靶板损伤进行评估的方法。结果表明：利用该方法所得到的计算结果与理论分析结果完全一致。这说明基于多元统计分析的靶板损伤评估方法是切实可行的，可以进一步应用于装备爆炸损伤评估与易损性研究中。     

静电放电抗扰度试验中辐射场若干特性的试验研究

国际标准IEc61000-4—2中对静电放电抗扰度试验方法和试验布局进行了规定，但是对间接静电放电（ESD）产生的辐射场没有进行描述。根据标准IEc61000—4—2，首先对水平耦合板和垂直耦合板放电时垂直耦合板上的场分布进行了分析，然后对几种医疗设备进行静电放电抗扰度试验。试验得出：1）对两种耦合板放电时，水平耦合板上电场强度和磁场强度随测试距离的变化趋势不同；2）试验结果对ESD模拟器的种类有着依赖关系。这些结果为研究电子设备静电放电抗扰度试验新方法、新标准和新的试验平台及诊断评估方法提供了参考依据。
