India’s Taliban Dilemma: To Contain or to Engage?

India’s Afghanistan policy in the 1990s is termed a zero-sum game of influence with Pakistan. New Delhi’s aversion to the pro-Pakistan Taliban regime is considered a marker of this rivalry. This paper revisits India’s approach towards Afghanistan and examines if New Delhi was necessarily averse to engaging with pro-Pakistan political factions during 1990s. Based on fresh primary interviews with former Indian policymakers, media archives, and official reports, the paper shows that India engaged with and accommodated pro-Pakistan factions after the Soviet withdrawal in 1989 until 1996. The Taliban’s rise to power in Kabul in September 1996 challenged India’s engage-with-all approach. Nonetheless, the decision to sever ties with the Taliban and to bolster anti-Taliban factions was highly debated in New Delhi. Many in India saw the Taliban as a militant Islamist force sponsored by Pakistan. For others, however, it was an ethno-nationalist movement representing Pashtun interests, and not necessarily under Islamabad’s control.     

Regina Maris and the Command of the Sea: The Sixteenth Century Origins of Modern Maritime Strategy

The concept of the command of the sea has its roots in medieval notions of the sovereignty of coastal waters, as claimed by several monarchs and polities of Europe. In the sixteenth century, a surge of intellectual creativity, especially in Elizabethan England, fused this notion with the Thucydidean term ‘thalassocracy’ – the rule of the sea. In the light of the explorations of the oceans, this led to a new conceptualisation of naval warfare, developed in theory and then put into practice. This falsifies the mistaken but widespread assumption that there was no significant writing on naval strategy before the nineteenth century.     

天基预警系统多体制传感器综合调度方法

为提高天基预警系统对多目标的跟踪能力,提出扫描传感器纬度区间扫描模式和凝视传感器目标群跟踪模式,并基于此种模式设计基于聚类的扫描传感器纬度区间扫描调度方法和凝视相机目标群跟踪调度方法。由于诸多传感器的工作模式、探测频率、测量误差、视场模型均不相同,推导不同探测频率、视线误差的多传感器联合观测跟踪的克拉美-罗下界计算公式。综合运用以上方法,建立多体制传感器综合调度优化方法。仿真试验表明,该方法比传统工作模式下的系统对多目标具有更高的跟踪精度。

【邀请论文】美军未来司令部探析——成立背景、主要职能与未来前景

新一轮科技革命的快速发展正推动战争形态从信息化向智能化演进。美军作为二战后始终位列世界第一的军事力量,正在积极设计未来战争以应对当前的“大国竞争”,2018年刚刚成立的陆军未来司令部正是在这一背景下产生的。未来司令部隶属于美国陆军,主要负责美陆军新型武器装备的研发、未来作战概念创新以及新兴军事科技的测试和应用。成立两年以来,未来司令部已经拥有了一套完善、严密的组织架构,创造了包括C5ISR作战概念在内的一系列理论成果,在空基导弹、远程精确火力系统等新型作战装备上也取得了众多进展。本文基于大量前沿文献研究,廓清了未来司令部的组织架构,总结了其主要职能,并对这一新设司令部的发展前景进行了展望和预测,期望能够为推进军队现代化和未来化建设提供有益启示。     

Self-Defense Militias,Death Squads,and State Outsourcing of Violence in India and Turkey

What explains the variation in states’ nonstate partners in civil warfare? States often use nonstate actors to do what their regular military forces cannot do well – navigate the local population. Some of their nonstate partners are ordinary civilians, while others are battle-hardened fighters with a rebellious or criminal past. The choice of proxy carries serious implications for the patterns and effects of violence during civil war, human rights, and international security. This article is the first to disaggregate the nonstate counterinsurgents and offer an explanation for why and how states use each type. It brings together the politics of collaboration with the politics of exploitation. The article shows that the state’s use of nonstate proxies is shaped by the supply of willing collaborators, the state’s ability to exercise control over them, and the trade-offs underlying the use of the different types of nonstate actors. The empirical evidence used to support this argument comes from a novel, comparative study of Turkey’s counterinsurgency campaign against Kurdish separatists and India’s counterinsurgency against Kashmiri separatists. The original data were collected through fieldwork in the disputed territories of each country.     

Beyond the Double Game: Lessons from Pakistan’s Approach to Islamist Militancy

States commonly take one of three approaches to militant groups on their soil: collaboration; benign neglect; or belligerence. All three approaches are present in Pakistan, where some groups also move back and forth among these categories. I employ the term “coopetition” to capture this fluidity. The dynamic nature of militancy in Pakistan makes the country an excellent laboratory for exploring a state’s assessment of the utility an Islamist militant group offers, and the threat it poses relative to other threats informs the state’s treatment of that group. In this article, I put forward a typology that situates Islamist militants in Pakistan in one of the above four categories. I also illustrate how a group’s identity, objectives, and alliances inform assessments of its utility and threat relative to other threats. In addition to enhancing our understanding of militant–state dynamics, this taxonomy builds on and helps to unify earlier typologies of Pakistani militancy.     

Coping with the refugee and migrant crisis in Slovenia: the role of the military

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.
