SADC has a poor record in advancing peace and security in Southern Africa. Many identify poor policy frameworks and weak technical capacities as the major obstacles. Laurie Nathan goes beyond these easy explanations in his important new book on SADC. Absence of common democratic values and reluctance to surrender state sovereignty are key factors preventing SADC from making progress according to this book. This article argues that Nathan overstates the case and that there are real prospects and potentials for making further progress in regional cooperation. The lessons from the history of European integration also points to the important role of regional leadership. South Africa, in coalition with other likeminded countries, may still be in a position to move the SADC project forward. 相似文献

The original Olson and Zeckhauser model of alliance burden‐sharing was based on the following four assumptions: (1) alliance defence is a pure public good; (2) allied nations make their security contribution decisions without consulting the other allies; (3) alliances produce only a single public good; and (4) alliance defence is produced with equal degrees of efficiency in all alliance nations. But while the first of these assumptions has received a great deal of attention in the alliance literature, the remaining ones have received comparatively less attention, particularly in terms of empirical analyses. This paper synthesizes a varied literature developed around these four assumptions, both substantively and theoretically, and shows that when these assumptions are brought closer to real world approximations, hypotheses regarding the potential for security cooperation with less free‐riding result. This article also provides a simple test of Western alliance burden‐sharing in the areas of military spending, development resources spending, and research and development spending that supports the hypothesis positing more equitable burden‐sharing. 相似文献

After only ten years in existence, the African Union (AU) has already made its mark on the landscape of peace and security in Africa. This paper seeks to explore the relationship between the AU's leading collaborative interstate security policy, the African Peace and Security Architecture (APSA), and sustainable peace in the Horn of Africa. It examines four countries – Djibouti, Eritrea, Ethiopia, and Kenya – and how engaging with the APSA through early warning systems can contribute to developing the elements necessary for sustainable peace, namely regional stability, conflict management, and good governance. 相似文献

The number of bilateral nuclear cooperation agreements surged during the “nuclear renaissance” of the past decade. This proliferation is only partially explained by the prevailing approaches that focus on strategic imperatives. To supplement these explanations, this study draws on neoliberal models of economic competition to posit that bilateral agreement negotiations also exhibit conditions of “uncoordinated interdependence” and maneuvering to gain market share. Case evidence suggests the contours of supplier state bids for civilian assistance are determined at least as much by considerations about economic competition as they are by positive strategic goals. In addition, this study identifies several cases of cooperation where there appears to be little or no strategic motive for export agreements. The study concludes that patterns of economic competition and the influence of peers in defined competitive spaces alter material payoffs and impact policies. It also identifies a surprising role for principled restraint in dampening strategic and economic competition in some dyads. 相似文献

任务分配是多UCAV协同控制的核心和有效保证。分析了影响目标价值毁伤、UCAV损耗、任务消耗时间等三项关键战技指标的因素,综合考虑实战中多UCAV同时攻击同一目标和使用软杀伤武器这两种典型情况对UCAV执行任务的影响,建立了针对攻击任务的多UCAV协同任务分配模型,并应用粒子群算法求解。仿真结果验证了模型的合理性和算法的有效性。 相似文献
