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

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

I study a two-period model of conflict with two combatants and a third party who is an ally of one of the combatants. The third party is fully informed about the type of her ally but not about the type of her ally’s enemy. In a signaling game, I find that if the third party is unable to give a sufficiently high assistance to her ally, then there exists a unique separating equilibrium in which the third party’s expected intervention causes her ally’s enemy to exert more effort than in the absence of third-party intervention; this worsens the conflict.  相似文献

British attitudes towards military intervention following the campaigns in Iraq and Afghanistan have undergone what appears to be considerable change. Parliament has voted against the use of Britain's armed forces in Syria and the public are unenthused by overseas engagement. Conscious of the costs and the challenges posed by the use of British military power the government has been busy revamping the way it approaches crises overseas. The result is a set of policies that apparently heralds a new direction in foreign policy. This new direction is encapsulated in the Building Stability Overseas Strategy (BSOS) and the more recent International Defence Engagement Strategy (IDES). Both BSOS and IDES set out the basis for avoiding major deployments to overseas conflict and instead refocuses effort on defence diplomacy, working with and through overseas governments and partners, early warning, pre-conflict prevention and post-conflict reconstruction. Developing a number of themes that reach from across the Cold War to more contemporary discussions of British strategy, the goal of this special edition is to take into account a number of perspectives that place BSOS and IDES in their historical and strategic context. These papers suggest that using defence diplomacy is and will remain an extremely imprecise lever that needs to be carefully managed if it is to remain a democratically accountable tool of foreign policy.  相似文献

恐怖危机事件与媒体相互依赖,二者之间存在着共生关系。媒体对于恐怖危机事件的处置既具有积极作用,又存在着一定的消极影响。在恐怖危机事件的报道中,媒体必须及时发布权威信息,把握好报道的内容,坚持正确的舆论导向,坚持以人为本的原则。  相似文献

ABSTRACT

Mexico’s Cora Indians have played an outsized role in national history, thanks to their skilful use of guerrilla tactics and success in forging strategic alliances with outside forces in defence of their cultural, territorial and political autonomy. Cora participation in elite struggles between Liberals and Conservatives (1850–73), and subsequently in the Mexican Revolution (1910–20), helped to shape the way that both conflicts played out in Western Mexico. Such participation also allowed Cora communities to keep hold of traditional landholdings in the face of political and economic reform, while sowing the seeds for the foundation of the Mexican state of Nayarit.  相似文献

ABSTRACT

The conventional wisdom about the 1992 US intervention in Somalia is that it was a quintessentially humanitarian mission pushed by President George H. W. Bush. This article challenges that interpretation, drawing on newly declassified documents. The Somalia intervention, I argue, was largely a pragmatic response to concerns held by the US military. In late 1992, as the small UN mission in Somalia was collapsing, senior American generals worried about being drawn into the resulting vacuum. Hence they reluctantly recommended a robust US intervention, in the expectation that this would allow the UN to assemble a larger peacekeeping force that would take over within months. The intervention ultimately failed, but the military learned useful lessons from this experience on how to achieve smoother UN handoffs in the future and thus effectively shift longer-term stabilisation burdens to the international community.  相似文献
