The State of UN Peacekeeping: Lessons from Congo

The article considers the state of UN peacekeeping through the prism of its long-running operation in the Democratic Republic of the Congo (DRC). Focusing in particular on the challenges raised by use of force and the protection of civilians in conditions of ongoing armed conflict, it argues that UN field operations must be aligned much more closely than they have been over the past 15 years to political and diplomatic efforts aimed at securing viable political settlements to internal conflict. The issues raised by the history of the UN’s troubled mission in the DRC are deeply relevant to the wider discussion of the organisation’s role in the field of peace and security.     

‘It isn’t over until the fuel cell sings’: A reassessment of the US and French pledges of nuclear assistance in the 1970s

Based on newly declassified archival documents, the aim of this study is to contribute to an improved understanding of the evolution of the non-proliferation regime through an examination of US and French nuclear cooperation agreements in the latter half of the 1970s. The four pledges of nuclear assistance examined – US assistance to Egypt and Israel, and French assistance to Pakistan and South Korea – failed to materialise by the end of the decade. Why did that happen? What caused the four pledges to fail? We find that the 1974 Indian nuclear explosion and the emergence of opposing domestic factions on the nuclear front in the supplier states generated major changes in US and French nuclear export policies, and also contributed to the development of a collaborative partnership between the two competing nuclear exporters, on the other.     

基于生命周期理论的军事环境安全策略

探讨了军事环境安全概念,并运用生命周期理论对国家军事环境安全的保障措施和宏观策略进行了初步研讨。军事活动一般可分为计划规划、具体实施和事后评价3个阶段。为了在新形势下更加经济、高效地保障国家军事环境安全,首先要加大军事活动环境影响评价力度、采用对环境破坏小的战法并在军购中推行环境准入制,即尽量从源头上控制重大环境问题出现。考虑到战争的特殊性,需要在战前预先储备必要的生态环境修复技术。

Space,China's Tactical Frontier

In recent years, China has made stunning progress in its satellite reconnaissance capabilities. Starting from almost no capacity for live surveillance ten years ago, today the PLA has gained the capability to support real-time tactical naval operations from space. China's suite of electro-optical, synthetic aperture radar, and electronic intelligence satellites would be key to its anti-access/area denial capabilities, through which the PLA could deny the United States military the capability to operate with impunity close to its shores. Furthermore, these achievements suggest a shift towards more military-dedicated space assets and form the contours of a crucial support system for expanded PLA operations.     

The Persistent Military Security Dilemma between China and India

This paper evaluates to what extent the improving Sino-Indian relations coincide with a mitigation of military threat perceptions. A critical review of the demilitarisation of the border, the military strategies with respect to the Indian Ocean and nuclear arms programmes, reveals that the two countries are still locked in a military security dilemma. Distrust still results in military balancing. The outcome is a complex and multi-level military balance of power that might not bring about peace but enhances stability.     

In the right place at the right time: US signals intelligence relations with Scandinavia,1945–1960

This paper demonstrates that US–Scandinavian intelligence relations in general, and Signals Intelligence (Sigint) relations in particular, during the period 1945 through 1960 were more extensive and complicated than had previously been believed. Bilateral US intelligence liaison relations with nominally neutral Sweden were of particular importance in the early years of the Cold War given its geographic location adjacent to the northwestern portion of the USSR. Moreover, the importance of Sigint received from the three principal Scandinavian countries covered by this paper (Norway, Denmark, and Sweden) proved to be quite important to the US intelligence community during the early years of the Cold War, when the US Sigint infrastructure was relatively weak and stretched thin by commitments in Asia and elsewhere. This paper covers the quantity, quality, and types of intelligence information provided to the US by each of the Scandinavian nations, demonstrating that the nature of US intelligence relations with these countries changed substantially as time went by.     

Insurgency by the numbers I: A reconsideration of the ecology of communist success in jiangxi province,China

Theorizing about Taliban operations in Afghanistan has its limits and it is possible that Kabul-centric strategies do not adequately address the unique circumstances of each region in the country. How exactly has the Taliban gone about attaining its objectives in Kandahar province and how have those approaches evolved since 2002? And how have the Taliban adapted to coalition forces' attempts to compete with the insurgency and stamp it out? The answers to these questions are critical in the formulation of any counterinsurgency approach to Afghanistan.
