Offensive Cyber Weapons: Construction,Development, and Employment

Deploying cyber weapons to damage Industrial Control Systems (ICS) is relatively easy because such systems are insecure by design. Maintaining communication with an activated cyber weapon, and ensuring its persistence, is harder but feasible.     

Who Really Dictates What an Existential Threat Is? The Israeli Experience

National security conception or securitization theory frames threats and conceptualizes the responses towards them. But in many cases, and especially in the Israeli context, there is a tendency to blur the nature and essence of different threats; security threats become strategic threats and then existential threats. In the Israeli context, because the broad concept of security is perceived, in most cases, as equivalent to military security, the meaning of the strategic threat will be framed, mostly, militarily, derived from military thought.

The article examines the nature of existential threats in the Israeli context and seeks to find the implications of securitization theory in this regard by analyzing the unique role of the military establishment and the influence of the military thought on strategic thought in Israel. The article also deals with the centrality of ‘military wisdom’ in the Israeli ethos and the sense of insecurity embedded in the Israeli narrative that leads to an ‘intellectual symbiosis’ between the political and the military echelons and finds this phenomenon as one of the major explanations for the influence of the military establishment on defining the nature of security threats as well as on the crucial decision to launch wars.     

Bush path to self-destruction: Charles Taylor and the Revolutionary United Front

This article explains the demise of Sierra Leone's Revolutionary United Front (RUF) rebellion. It argues that the main cause of this fate was the group's relationship with its primary sponsor, Charles Taylor. The RUF's dependency on Taylor's patronage, coupled with the rebellion's weak organisational endowments harmed the group's prospects of success. Based on original research, the article shows how Taylor used the RUF as a strategic instrument for his own regional interests, which led to the group's unravelling. More broadly, the article speaks about proxy warfare in Africa and how the relationship between resource flows and rebellion are not always beneficial to rebels as one might expect.     

Army reconstruction in the Democratic Republic of the Congo 2003–2009

Since the peace agreements of 2002–2003 which ended the second war in the Democratic Republic of Congo, reconstruction of the army has been an inherently political process, in common with other attempts to carry out security sector reform (SSR). This article briefly sketches out the Congolese army's history, then attempts to fill a gap in the literature on Congolese SSR by detailing what can be found of the actual structure and shape of the present army. The efforts that have been made to reform the army are then examined, followed by a conclusion which examines the major issues and possible ways forward.     

A more complex and conventional victory: revisiting the Dhofar counterinsurgency, 1963–1975

Following the emergence of a communist regime in South Yemen and the multiplication of subversive movements in the United Kingdom's Gulf protectorates, British policymakers genuinely feared the spread of communism throughout southern Arabia. Defeating the People's Front for the Liberation for the Occupied Arabian Gulf (PFLOAG) insurgency in Oman's Dhofar province was considered central to preventing such an outcome. In their pursuit of victory, British officers overthrew the sultan of Oman, escalated the war by conducting attacks in South Yemen, and, ultimately, appealed to Islam as a means of rallying support against communism. However, lessons learned in previous counterinsurgencies (Malaya, Kenya, and Borneo) proved of only limited value in Oman's physical and cultural environment. Unfortunately, none of these measures worked as anticipated. Only Iran's direct military intervention and the dramatic growth of Oman's financial resources after the 1973 oil crisis provided the resources to conduct large-scale offensive operations. Even so, victory was only achieved in 1975 because the rebellion's leaders unwisely attempted to oppose the Anglo–Omani offensives conventionally.

试论联合国维和行动的法律性质

联合国维持和平行动的法律性质在国际法学界一直存在争议。在维和行动与其他国际军事或准军事行动的辨析中我们可以看到维和行动自身所独具的法律特征。维和行动的法律依据尽管未有定论,但依据其实践与发展的现实状况,我们可以将它的法律性质概括为:联合国属准军事行动性质,国际法约定的默示授权性质,维护国家间独立平等的工具性质等。
