Africa is arguably the most important regional setting for United Nations peacekeeping challenges. In the 1990s, extensive efforts have been made by the United Nations in the fleld of peacekeeping with the speciflc aim of reducing the levels of conflicts on the continent. Another significant development relates to the fact that organisations in Africa have started to feature as important peacekeeping instruments in recent years as it is increasingly being accepted that there is a need for such institutions to take care of their own security requirements. However, a key issue at stake is the need to achieve greater consistency with regard to third-party intervention in African conflicts. A look at the more glaring examples of multinational operations in the name of peace and security gives a sense of the magnitude and difficulties often experienced during such endeavours. In addition, both past and current operations have brought to light certain perspectives and lessons that require careful analysis and study. In this article, an overview is given of some of the perils and challenges associated with multinational operations in the realm of peace and security. Specifically, the focus is on Africa and on key issues and challenges regarding the strategic and operational management of such operations in view of the need to consider a more integrated approach towards multinational operations in support of peace and security in Africa.  相似文献

Chinese writings on the workings of nuclear stability, deterrence, and coercion are thin and politicized. Nevertheless, it is possible to glean, from direct and inferential evidence, rather pessimistic conclusions regarding Chinese views of nuclear stability at low numbers. While China has been living with low numbers in its own arsenal for decades, today it views missile defense and advanced conventional weapons as the primary threat to nuclear stability. More generally, China views nuclear stability as wedded to political amity. Because none of these would be directly addressed through further US and Russian arsenal reductions, China is unlikely to view such reductions as particularly stabilizing. While there is little in Chinese writing to suggest lower US and Russian numbers would encourage a “race to parity,” there are grounds to worry about China becoming more assertive as it gains confidence in Beijing's own increasingly secure second-strike forces.  相似文献

We model an oppressor aiming at victimizing an excluded group in his country, with two main variants. A foreign power affects his behaviour using either conditional aid, subject to the dictator’s participation constraint, or the threat of sanctions, broadly defined, subject to the credibility constraint. The choice between the two is either determined by the latter, or by their relative cost. Aid is preferred when the threat of sanctions is ineffective, and sanctions are too expensive. Sanctions might be imposed, if the threat is ineffective. A case study of the Iraqi Kurds after Iraq was subject to sanctions is presented.  相似文献

The possibility of domestic production raises a difficulty for arms export control measures, since embargoes, by raising the effective price of imports, increase the incentive for domestic production. We address this issue by developing a partial equilibrium model of the international arms market We compare three arms export regimes involving the exporters of high‐technology arms, with a particular focus on the effect of emerging domestic production: laissez‐faire trade, the uncoordinated regulation of exports and a producer cartel consisting of coordinated regulation. The main conclusion is that the possibility of domestic production significantly changes the nature of these stylized export regimes.  相似文献

This paper empirically examines whether the aging of a fleet affects operational availability and operating cost using a unique data-set on the 117 47-foot Motor Lifeboats (MLBs) of the United States Coast Guard (USCG). Procured from 1997 to 2003, the 47-foot MLB is the standard lifeboat of the USCG and all 117 MLBs remain in service. The aging of the MLB fleet has resulted in higher annual operating costs and lower operational availability, although the nature of this relationship remains unclear. Our estimation strategy utilizes an error components estimator to examine these issues. We employ three variants of the dependent variables (i.e. the standard logarithmic transformation as is most commonly seen in the literature, inverse hyperbolic sine [IHS], and level outcomes). The point estimates from the standard logarithmic model finds operational availability for the MLBs decreases at a rate between 0.83 and 1.8% per year and cost increases at a rate between 0.33 and 7.81% per year. Similar effects are shown with the IHS and level outcome specifications. In terms of nonlinearity effects, we find the most pronounced changes in operational availability and cost occur for MLBs aged 15 years or more (in comparison to younger MLBs).  相似文献
