ABSTRACT

The paper’s goal is to analyses the potential of the Iranian defence industry, including both research-and-development and production capabilities. It is argued that, despite official statements about the great power and sophistication of the Iranian defence industry, in reality its capabilities are very limited and cannot meet the operational needs of the Iranian armed forces. At the same time, it is argued that many official releases, which are abundantly available in the Iranian press and often unthinkingly repeated by the Western media, do not present the real and value of military products, but are rather a tool for deception and propaganda.  相似文献

ABSTRACT

The United States’ global strategic outlook has shifted markedly since the end of major combat operations in Iraq and Afghanistan. As the United States’ strategic posture shifts, the nature of military operations is simultaneously changing rapidly. Many analysts predict that cyber-operations, autonomous weapons systems, artificial intelligence, and clandestine special forces operations will be central features in future conflicts. Although often overlooked by scholars and policy analysts, defence contractors are integral to the development and implementation of these emerging categories of warfare. This inquiry examines the evolving nature of the American defence industry and the roles corporations play in current theatres of conflict. Surprisingly, rather than becoming less reliant on defence contractors after their much-maligned performance in the wars in Iraq and Afghanistan, American military and intelligence agencies have become more dependent on the private sector as technology becomes increasingly central to warfare.  相似文献

ABSTRACT

Bagayoko, Hutchful, and Luckham correctly argue that the structures, characteristics, and operating methods of official security institutions in Africa have been somewhat neglected, with a lack of much recent research. The Somali National Army (SNA) sits among these lacunae. Its formal structures can be used as a skeletal starting point and springboard to start to draw the network diagrams that chart informal linkages. This is why recent declassification decisions by U.S. intelligence bodies, coupled with period documents released to the UK National Archives, hold significance in helping us understand early hierarchical SNA arrangements. They show the steady build-up in size of the force, to 1987, to about the time the civil war began to fragment the state.  相似文献

ABSTRACT

Over a decade of security force assistance (SFA) initiatives to build an effective Somali National Army (SNA) failed because of the interrelated effects of political, contextual and operational challenges. The key political challenges were interest asymmetry between international actors and Somali elites, insufficient focus on institution-building and a lack of donor coordination. The principal contextual challenges in Somalia were the legacies of two decades of state collapse and the negative effects of clan dynamics. The main operational challenges were building an army while simultaneously fighting a war, the complexities of military integration, and the severe capability gaps afflicting the SNA.  相似文献

ABSTRACT

The rising trend of kidnapping targeting women has shown that counterinsurgency does not begin and end with the strategic advantage of state security providers in the security market and the field. Kidnapping of females by Boko Haram insurgents threatens human security and hinders sustainable development goals in Northeastern Nigeria. With primary and secondary sources, this qualitative study examines how Boko Haram insurgents target women in Northeastern Nigeria. The paper argues that community driven security strategy achievable through the collaboration between state and traditional security providers, can prevent the entry and easy escape of the insurgents. It concludes that the forces of order should sustain a policy of stop and searches until insurgents are defeated along with a programme of community-based human rights education and insurgency emergency response system for quick response to security threats.  相似文献
