Putin – the masked nemesis of the strategy of ambiguity

Recent events demonstrate the complex and adaptive approach employed by Russia to reassert influence in Europe. The changing face of Russia’s strategy commenced in 2007 when it launched a crippling cyber-attack against Estonia. This was followed by a large Russian conventional attack against Georgia in 2008, occupying two large areas of the nation. 2014 witnessed the Russian annexation of Crimea where in just a week, Russia seized control of Crimea “without firing a shot.” The annexation of Crimea was rapidly followed by a Russian inspired and led subversive war in eastern Ukraine. The common thread among these diverse Russian operations is its use of ambiguity to confound and confuse decision makers in the West.     

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.     

Remembering and forgetting Mirambo: Histories of war in modern Africa

ABSTRACT

While the study of organised violence is considered essential to understanding the history of the West, and accordingly imbued with various layers of meaning and remembrance, war is widely regarded as inimical to the modern nation in Africa and stable development more broadly. Using examples drawn from primarily from East Africa, this paper considers the ways in which warfare in the deeper (‘precolonial’) past has been framed and envisioned in recent decades, in particular by governments whose own roots lie in revolutionary armed struggle and who began life as guerrilla movements. While in some cases particular elements of the deeper past were indeed mobilised in pursuit of contemporary political goals, in many other scenarios histories of precolonial violence were beheld as problematic and unworthy of remembrance. This paper highlights the paradox and ambiguity which has attended the memory of key aspects of Africa’s deeper past.     

The UK,interrogation and Iraq, 2003–2008

The UK’s interrogation operations during the conflict in Iraq (2003–2008) are often portrayed by the media as involving significant amounts of mistreatment. This article demonstrates that these practices are not necessarily representative of the UK’s interrogation operations across this conflict. In doing so it contributes to the limited literature on the practice of interrogation and on the UK’s combat operations in Iraq. The UK’s interrogation capability, and therefore its intelligence-gathering capability, is shown to have rested primarily with the military’s Joint Forward Interrogation Team (JFIT). The JFIT suffered from limitations to the number, training and experience of its interrogators and interpreters. It is argued that maintaining a permanent, higher level of preparedness for interrogation by the British armed forces is desirable.

Al Qaida on the US invasion of Afghanistan in their own words

This article consists of selected translations from captured interviews and dairies of Al Qaida members. The time period covered is from mid-2001 to early 2002 and concerns their operations in Afghanistan. The material clearly conveys a range of emotion, from confident to despondent, as well as efforts to contest the US actions. The first several pages give the reader context and some possible “lessons learned,” but the story(ies) are best told by the Al Qaida members themselves. All names are pseudonyms.     

Does Intent equal Capability? Al-Qaeda and Weapons of Mass Destruction

The prospect of terrorists deploying weapons of mass destruction (WMD) is often referred to as the foremost danger to American national security. This danger has become more realistic because of al-Qaeda's expanding global network and the expressed willingness to kill thousands of civilians. In the past four years, numerous media reports have documented the group's ongoing quest for WMD capabilities; many reports have detailed al-Qaeda members’ attempts to manufacture or obtain certain chemical, biological, radiological, and nuclear (CBRN) agents to use in WMD against targets in the West and the Middle East. Yet the question remains: Does al-Qaeda's current WMD capability match its actual intent? While most studies of the group have focused on its explicit desire for WMD, allegations of CBRN acquisition, and the killing potential of specific CBRN agents, few open-source studies have closely examined the evolution of al-Qaeda's consideration of WMD and, most notably, the merit of actual CBRN production instructions as depicted and disseminated in the group's own literature and manuals. The following report will examine the history of al-Qaeda's interest in CBRN agents, the evolution of the network's attitude toward these weapons, and the internal debate within the organization concerning acquisition and use of WMD. More so, the following research will assess the validity of actual CBRN production instructions and capabilities as displayed and disseminated in al-Qaeda's own literature and websites.     

Late Medieval Lance Use: Mounted Combat and Martial Arts in Western Europe from the 14th to the 16th Century

Despite the lance’s status and the amount of attention the couched lance has received in historiography, study of its martial art has been neglected. The various lance types and techniques used by western European cavalry have only recently begun to receive scholarly attention. Additionally, Medieval European lance use has too often been studied in isolation, without an adequate understanding of the idiosyncratic and asymmetrical dynamics of mounted combat. Although the charge with the couched lance was a valid tactic, it was only one of many. Light and heavy lances were used in one hand or two to trip, block, unhorse, and wrestle. These techniques were governed by the harsh laws of distance, speed, impact, iron, and asymmetry. By utilizing the surviving Fechtbücher and several Peninsular and Near Eastern sources, a brief foray into the diverse techniques of lance use and their purposes has been attempted here.

The practice and theory of British counterinsurgency: the histories of the atrocities at the Palestinian villages of al-Bassa and Halhul, 1938–1939

This article details two largely unreported atrocities by British forces operating against Arab rebels during the Arab revolt, 1936–9, at the Palestinian villages of al-Bassa and Halhul. It then examines the military-legal system that underpinned and authorised British military forces operating in aid of the civil power, suggesting that the law in place at the time allowed for a level of reprisals and punitive actions, such as happened at al-Bassa and Halhul. The article does not conclude that the law allowed for atrocities but it does argue that it gave a basic form and understanding to an operational method that was brutal and could lead to atrocities. It thus tests the idea in much of the literature on counterinsurgency that the British were restrained and used minimum force when compared to other colonial and neo-colonial powers fighting insurgents.
