Fourth Generation Warfare is a theory of contemporary warfare that posits a number of different ideas that are able to shed light on current conflicts. Whilst much of the debate has been concentrated on the linear development of warfare and also on analysis of the current situation of US forces in Iraq, it has resonance for a number of different conflicts taking place in Africa, if only because the US has become involved in contemporary conflicts in Somalia and the Mahgreb. There are clearly significant issues with the US-centric, flawed linear approach to history, but the actual analysis of modes of warfare has much to offer policymakers in a continent that is under-represented in the literature, and is also in danger of being forgotten in the shadow of analysis of Iraq. This paper moves on from criticising the stepped approach to history and looks at patterns of warfare in contemporary Africa, arguing that there is much in the theory that could be used to explain seemingly illogical tactics or patterns, and thus has much to tell policymakers engaged in conflict analysis.

Making extensive use of primary archival documents, this article seeks to explore whether airpower in three of Britain's most significant post-war colonial counterinsurgency campaigns, Malaya, Kenya and South Arabia, was an unnecessary part of British strategy, offering little useful military force due to the futility and strategic damage rendered by offensive bombardment, or whether airpower was indeed an unsung factor that provided operational flexibility through its effectiveness in a supply context, as well as its intelligence role in providing valuable aerial reconnaissance. In all three case studies the role played by the RAF in medical evacuations, in troop drops, in crop spraying during food-denial initiatives, and in providing ‘Voice Aircraft’ for the propaganda campaign, provide insights into an under-explored component of Britain's politico-military efforts in counterinsurgency in the 1950s and 1960s and suggests that the main strategic value of airpower in counterinsurgency, then and now, lies in its non-kinetic functions.  相似文献

A fundamental contradiction has been built into America's intervention in Afghanistan since the first days of the war in 2001. On the one hand, US policymakers have viewed the promotion of liberal democracy, economic development, and strong centralized state institutions as essential to achieve victory over the long term. On the other hand, however, the US has relied on local warlords to win its battles against the Taliban from the first days of the intervention. The Obama administration's tortured policy review reflects the intractable dilemmas involved in trying to build a modern democratic state while relying on local warlords as crucial allies in the war against the Taliban.  相似文献

In the course of the 2006 Lebanon War the Israel Defense Forces (IDF) employed special operations forces (SOF) for raids against Hizb'allah's command and control structure. This article argues that a faulty conceptualization of the value of special operations and misguided expectations determined by the new IDF concept of operations impacted adversely on the employment of SOF for this kind of operations. Both these elements contributed in turn to substantially degrade SOF performance in the context of the war.  相似文献

ABSTRACT

This article explores how two influential American policy makers—Paul Nitze and McGeorge Bundy—wrestled with the idea of a norm against the use of nuclear weapons. Existing scholarship has overlooked how both Bundy and Nitze came to understand the idea of nuclear non-use, especially related to the credibility of threats to use nuclear weapons. Using documentary evidence from their personal papers, this article illuminates the thinking of Bundy and Nitze, finding that both engaged with the idea of a norm of non-use of nuclear weapons in their strategic writing and thought.  相似文献

ABSTRACT

Decade-long security cooperation and counterterrorism engagements in Nigeria have failed to bring down Boko Haram or at least weaken its terrorist structures and transnational spread. I argue that disconnects between counterterrorism-assistance seeking states and their superpower sponsors are implicated in the intractability of Boko Haram's insurgency in Nigeria. Why is the U.S. counterterrorism intervention to individual MNJTF countries (i.e. troop contribution, military funding and intelligence support) ‘lopsided’, ‘fragmented’ and ‘unevenly distributed;’ and how are these implicated in the fight against Boko Haram terrorism? This has impacted negatively on MNJTF countries – lack of cooperation, divisiveness and individualism in coordinating and forging offensives against Boko Haram. These concerns interface several blind spots in the picture of external influences on military’s approach to Boko Haram. I elicit primary data from top military officers. I conclude by predicting the implications and consequences of these counterterrorism complexities, and their potency to defeat or encourage Boko Haram terror.  相似文献

The design of military posture is an exercise in confronting potential enemies’ capabilities within the context of geographic, technological, temporal, political and economic constraints. No formal model is capable of encapsulating the essentials of so complex an environment for closed or simulated analysis, but it is useful to have an informal framework within which to reason interactively within these dimensions.

This paper presents such a scaffolding, patterned on the notion of a military posture as the output of an economic process whose structure reflects important determinants of the characteristics and extents of weaponry and expenditures that are appropriate to the environment within the feasibility set determined by the constraints. The analysis remains at an abstract level, but it does highlight the important shifts toward preparation for littoral warfare, greater reliance on reserve rather than active forces, and necessary changes in missions among military departments.  相似文献
