Pool it,share it,or lose it: an economical view on pooling and sharing of European military capabilities

In a general and economical view, this article analyzes methods and mechanisms for the pooling and sharing of military forces and weapons inside the European Union (EU) in times of scarcity. Pooling and sharing could improve the EU military capabilities significantly if differences in location factors were taken into account and all states would focus on their respective strengths. More competition and less concentration are the keys to ensuring guaranteed access to military assets. Pooling and sharing are likely to be successful only if large states enhance their emphasis on collective defense by mutual aid and self-help, and reduce particularistic and parochial interests of local gain. The realm of personnel has the most potential for improvement but any change is likely to generate policy implications.     

Lessons in airpower projection: Indochina and Algeria

The lessons from the two French counterinsurgencies, Indochina and Algeria, give rise to a new understanding of the projection of airpower in remote and hostile environments and the purpose, design, and use of aircraft in counterinsurgency. In both Indochina and Algeria, the campaigns were ones of poverty, and it is their imaginative management under severe resource constraints that provides thoughtful and applicable lessons for today. In both cases, airpower held the promise of delivering victory and solving the resource issue. In Indochina, acquisition of the needed aircraft, operating knowledge, and experience came too slowly to realize this promise. In Algeria, the French embraced the lessons from Indochina and were quite successful and innovative in the use of airpower. The lessons can be reduced to four requirements: (1) a network of airfields for liaison, ground-support, and intra-theater airlift to enable effective air support of ground forces; (2) a solid, reliable, and simple ground-support aircraft capable of operating from forward airfields within range of ground engagements; (3) a capable intra-theater heavy-lift transport to supply the extended ground forces; and (4) helicopter capability to enhance tactical troop mobility and support.

Building the next nuclear community

This viewpoint takes stock of the changes in the strategic nuclear landscape in recent decades and reflects on its consequences on the policy community. It finds that the number and scope of issues have expanded considerably; they have manifested themselves in many more regions of the world; and they have become deeply politicized and polarized. The consequences have been twofold: the nuclear policy field has seen the development of an increasingly diverse expert community composed of highly specialized functionalists and regionalists, and it has become ever more divided into two entirely separate ideological camps—one that believes in deterrence, the other in disarmament. The stove-piping of expertise and the widening gap between deterrence and disarmament ideologies are immensely problematic because, in different ways, they stand in the way of the emergence of a better and safer nuclear future. Looking ahead, it is critical to “bust the silos of expertise” and to build bridges between the deterrence and disarmament ideological camps. Only such a community-building effort will help solve today’s and tomorrow’s nuclear challenges.

Gender,feminism and food studies

Policy research and scholarship on food has rapidly increased in recent decades. The attention to ‘gender' within this work appears to signal important practical and academic efforts to mainstream gendered understandings of food consumption, distribution and production into expansive conceptualisations of human security. This article argues that the gender-related work on food has wide-ranging and often troubling political and theoretical foundations and implications. Often growing out of knowledge regimes for managing social crises and advancing neo-liberal solutions, much gender and food security work provides limited interventions into mainstream gender-blind work on the nexus of power struggles, food resources and globalisation. A careful analysis of knowledge production about gender and food is therefore crucial to understanding how and why feminist food studies often transcends and challenges dominant forms of scholarship and research on food security. This article's critical assessment of what food security studies in South Africa has entailed at the regional level and in global terms also focuses on the methodological and theoretical feminist interventions that can stimulate rigorous conceptual, research and practical attention to what has come to be understood as food sovereignty.
