The Carnation Revolution on 25 April 1974 toppled the authoritarian regime in Lisbon. It is fallacious to conclude, however, that the 1974 coup d’état signaled Portugal's defeat in the Colonial War. The status of each conflict on the eve of the Carnation Revolution varied, and it was by no means inevitable that Portugal would have been defeated in all three theatres had the coup not occurred. This brief research note therefore advances a novel approach to examining the Colonial War by assessing the outcomes prior to the 1974 coup. In particular, the author proposes that Portugal achieved military victory in Angola and Mozambique, but was defeated in Guinea-Bissau.  相似文献

The Biological and Toxin Weapons Convention (BTWC) underpins the international regime to control biological weapons. The strength of the treaty however relies on national implementation. The first step for many states party to the Convention is drafting appropriate national laws and regulations. So far, 32 countries in Africa are signatory to the BTWC. More recently, in 2004, the United Nations Security Council adopted resolution 1540, which requires all UN Member States to put in place legislation to prevent the illicit trafficking of material that could be used to develop weapons of mass destruction. The need for such wide-ranging legislation is recognised African countries but its creation and implementation pose specific challenges.  相似文献

This article explores the proliferation of illicit small arms and light weapons in the West African sub-region and efforts by the regional Economic Community of West African States (ECOWAS) to deal with the problem through the ECOWAS Declaration of a Moratorium on the Importation, Exportation and Manufacture of Small Arms and Light Weapons in West Africa. The paper analyses the degree of compliance with the Moratorium by four ECOWAS member states, namely, Ghana, Nigeria, Sierra Leone and Mali.  相似文献

The Constitutive Act of the African Union (AU) provides for the right of the continental body to intervene in the face of war crimes, genocide and crimes against humanity. According to its formulation, Article 4(h) intervention entails military force, which is triggered when a target state fails to discharge its duty to protect its population from mass atrocities. Although Article 4(h) is an ambitious statutory commitment to intervene in a member state by the AU, the Libyan crisis in 2011 showed the ambivalence of the continental institution to act in a decisive and timely manner. The AU's failure to invoke Article 4(h) exposed the need for building the capacity and political will to intervene and to interpret Article 4(h). Therefore, the primary focus of this article is on how Article 4(h) should be interpreted. Flowing from the Pretoria Principles, which seek to provide clarity on the implementation of the AU's right of intervention, Article 4(h) should be viewed as a duty rather than a right to prevent or stop mass atrocities. The duty dimension of Article 4(h) derives from the international instruments that AU member states have ratified to prevent mass atrocities. Rather than being a paper tiger, Article 4(h) should be used in a proactive and timely manner as a military option available to the AU to persuade member states to prevent or halt atrocities. As a last resort, military force pursuant to Article 4(h) should aim at protecting the population at risk and pursuing the perpetrators in order to avoid contravening Article 2(4) of the Charter of the United Nations (UN). Although military intervention can save lives in the short term, it cannot necessarily address the underlying, structural causes of atrocities, such as ethnic rivalries, economic inequalities and scramble for natural resources, among others. Therefore, the prevention of mass atrocities should not be equated with, or be seen through the prism of, Article 4(h) intervention alone. The focus should instead be on the entire spectrum of preventive strategies at the disposal of the AU in the face of mass atrocities, including the African human rights system and the African Peer Review Mechanism.  相似文献

After the fall of the Taliban regime in 2001, several thousand Afghan Taliban forces fled across the border to Pakistan, and the area became a safe haven for Afghan insurgents. In 2014, the transnational dimension of the insurgency is still highly prominent. Although regional support for insurgents is not uncommon, how to counter this aspect is mostly ignored in counterinsurgency (COIN) theory and doctrines. In this article, a regional counterinsurgency framework is developed, using the regional counterinsurgency efforts in Afghanistan as an example. The framework will facilitate the systematic inclusion of regional COIN measures in theory and doctrine.  相似文献

We introduce a generalized orienteering problem (OP) where, as usual, a vehicle is routed from a prescribed start node, through a directed network, to a prescribed destination node, collecting rewards at each node visited, to maximize the total reward along the path. In our generalization, transit on arcs in the network and reward collection at nodes both consume a variable amount of the same limited resource. We exploit this resource trade‐off through a specialized branch‐and‐bound algorithm that relies on partial path relaxation problems that often yield tight bounds and lead to substantial pruning in the enumeration tree. We present the smuggler search problem (SSP) as an important real‐world application of our generalized OP. Numerical results show that our algorithm applied to the SSP outperforms standard mixed‐integer nonlinear programming solvers for moderate to large problem instances. We demonstrate model enhancements that allow practitioners to represent realistic search planning scenarios by accounting for multiple heterogeneous searchers and complex smuggler motion. © 2013 Wiley Periodicals, Inc.

Israel and Hezbollah have applied the lessons learned from the 2006 Lebanon War and have been preparing for a future conflict with both sides aiming for a more decisive victory. With improved capabilities from 2006, future hostilities will be far more destructive. This article analyzes their performance in 2006 and the lessons they have drawn to predict what a future conflict is likely to look like. The article analyzes both parties in three categories: ground forces; rockets, missiles, and anti-armor weapons; and lastly, Israel's air and sea dominance and Hezbollah's efforts to counter that dominance. Finally, this article argues that, contrary to conventional wisdom, a large-scale conflict between Israel and Hezbollah is unlikely to become a larger regional conflict involving Syria and Iran.  相似文献

Since 2000, international organisations such as the UN, NATO and the EU, but also countries, have started to apply what has been called the comprehensive approach to crisis management. This article unpacks this comprehensive approach implemented by the Dutch in Uruzgan province, Afghanistan. It first borrows and expands a conceptual framework developed by De Coning and Friis. Subsequently, it maps the different sorts of coherence in the mission by applying the framework. It shows how in practice there was not one single comprehensive approach, but many different forms of interaction between a number of organisational units. Each interaction had its own distinct issues and its own level of coherence. The level of coherence differed depending on the level at which the interaction took place – strategic at headquarters level versus operational at field level – and at what point in the mission it happened – in most cases it moved towards more cohesion.  相似文献

ABSTRACT

This paper challenges recent claims that competitive market dynamics incentivize Private Military and Security Companies (PMSCs) to fully commit to providing effective services, thereby reducing the duration of civil war. Our assessment of a most-likely case scenario for this argument – Sierra Leone – reveals four critical problems. First, there is rarely direct competition, even if numerous companies are present. Second, the presence of multiple PMSCs usually represents a collaboration among subsidiaries providing distinct services, often under the same corporate umbrella. Third, data aggregation obfuscates the overlap of PMSC presence, inflating the amount of perceived competition. Finally, we raise concerns regarding how quantitative analyses can conflate conflict intensity with conflict termination.  相似文献
