美军这样开打信息战

与其他国家特别是发展中国家军队相比,信息优势是美军的“核心优势”。正是因为拥有这种“核心优势”,美军在冷战后的几场高技术局部战争中才屡战屡胜。已经结束的伊拉克战争进一步显示了美军的这种“核心优势”。在此次战争中,作为拥有绝对信息优势的美军无论是侦察、情报、指挥、控制、作战,还是后勤保障、空间支援等环节,都体现了以信息为主导,呈现出不同于以往的一些特点。

论美军心理战的概念演进

信息网络时代的心理战已经成为维护国家安全的重要手段。纵观美军心理战发展历史,相继出现了"宣传""心理战""心理行动""军事信息支援行动"等概念,这些概念的演进过程实质上是美军不断探索、发展和完善心理战的过程,反映了国际形势和国家战略的深刻变化。美军心理战概念提出的过程以及在此基础上美军心理战概念体系的构建,与美官方机构的定义系统结合,分析系列相关概念特点,对探讨美军心理战概念演进大有裨益,亦可为战略支援视域下的心理攻防建设提供参考。

Terrorism,insurgency, kidnapping,and security in Africa's energy sector

Energy continues to serve as the bedrock of modern economies and the main driver of modern society. For Africa, the production and supply of energy resources such as crude oil, natural gas, uranium, coal, biomass, biofuels and other renewables are an important source of employment, rents, taxes, royalties and profits. This sector brings in several tens of billions of dollars of revenue annually. The production and delivery of such resources, however, depend on critical infrastructures such as pipelines, refineries, processing plants, terminals, rigs, electrical energy pylons, substations, pump stations, vessels, and tankers. These infrastructures have been attacked by terrorists, insurgents, vandals and saboteurs, all of whom see them as targets against which to register their grievances and extract concessions from the state. This paper is a chronological account of some of the documented incidents of terrorism, insurgency, kidnapping, destruction, sabotage, and human casualties suffered in the oil and gas sectors in Africa between 1999 and 2012. It is based on data extracted from the databases of the RAND Database of World Terrorism Incidents and the University of Maryland's Global Terrorism Database (GTD).

Bourdieu’s capital and insurgent group resilience:a field-theoretic approach to the polisario front

The conflict between the rebel group, the Polisario Front, and the Kingdom of Morocco is nearing its 43rd year. Though under-reported, the conflict itself garners attention for the resilience – some would say tenacity – of the ethnically Sahrawi Polisario Front. Despite shifting regional and international politics and the nearly 150,000 Sahrawi refugees waiting in nearby Algerian camps, the rebel group has survived. What explains its resilience? This article uses Bourdieu’s ‘forms of capital’ to understand the Polisario Front’s persistence. Based on field research in Algeria, Western Sahara, and the United States, it finds that social, cultural, symbolic, and economic capital may provide an explanation.

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.

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.

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.
