ABSTRACTFollowing frustrating campaigns in Iraq and Afghanistan, Western interventions are becoming more limited, with troops being deployed for short bursts and residual peace-building tasks being left to others. Although this approach limits exposure for the intervening government, it struggles to achieve meaningful political change. Examining the comparatively successful British intervention in Sierra Leone (2000–02), this article identifies the conditions for effectiveness in these campaigns. It challenges the historiography of the case by framing armed confrontations and raids as enablers of politics rather than ends in themselves; indeed, in both the conduct and study of intervention, politics must reign supreme. 相似文献

Canada is now at a crossroads unlike any other period in its history and needs to carefully consider which path to take. With the new Trudeau government comfortably ensconced since the defeat of the Harper government in the fall of 2015, a variety of competing interests have emerged in an attempt to turn Canadian policy back to a more nostalgic period of the 1970s that some see as preferable to the institutional lash-up that existed since the rolling out of the Canada First policy in the 2000s. That nostalgic period is, however, misunderstood both willfully for political purposes but also through a lack of historical context. Firmly rooting future actions in a blunt analysis of national interests is preferable to the alternative. 相似文献

Palestinian uprising, ‘intifada’, aggravated the recession of 2001–2004 in Israel which dampened demand for labor in all industries except security services. We use this exogenous shock to study whether a cohort of young men who were attached to temporary jobs as security guards for unusually long periods of time during the intifada landed on an inferior career path, as compared to security guards from a pre-intifada cohort. We find that the intifada cohort had less employment mobility, were ultimately less connected with the labor market, and earned less on jobs after the security services, relatively to the pre-intifada cohort. 相似文献

The United States is launching another defence innovation initiative to offset the growing military-technological might of countries such as China, Russia and Iran. However, by utilising emerging technologies from the commercial sector to achieve greater military power the US may further open up the technology gap within NATO. This raises serious questions for NATO’s European allies. This article probes the nature of the US’s latest innovation strategy and sets it within the strategic context facing Europe today. Whether European governments, firms and militaries will join the US in its new defence innovation drive will hinge on politico-military and industrial considerations. 相似文献

China’s expanding strength and ambition may foreshadow a violent conflict with the United States. I describe two scenarios about how such a conflict would unfold. The article begins by examining the prospects for nuclear escalation, drawing on theories about politics, psychology, and inadvertent escalation. It then examines the prospects for protracted conventional war, a scenario that has received far less attention. I present a new theory of protraction based on technology, geography, and domestic politics. After assessing the logic of both scenarios against a hypothetical US–China conflict, I discuss which is more likely. The conclusion points to a sobering trade-off: efforts to avoid nuclear catastrophe increase the chance of a long and grueling fight. 相似文献

This paper investigates the effect of the deployment of United Nations Blue Helmets on economic activity in South Sudan with a special focus on agricultural production. Since UN troops are predicted to improve security, in particular, we expect a positive relationship between deployment of UN blue Helmets and cereal production. We test our hypothesis using an original data-set including all the 78 South Sudanese counties over the period 2009–2011. We control for the non-random assignment of UN troops through an Instrumental Variables approach. Our empirical results show that a 10% increase in the size of the troop allows the production of additional 600 tonnes. 相似文献

The last decade has seen several advances in the study of deterrence. These advances have sparked some strong disagreements regarding interpretation of the models and what their contributions signify. This paper appraises the discussions from a model theoretic perspective. It is argued that when comparing rivalling models three aspects; (i) target, (ii) criteria and (iii) type of purpose should be taken into account in order to make a proper appraisal. Informed by these aspects it is evident that the three deterrence models analysed address different aspects, in different ways and to different ends. From this perspective, the so-called Perfect Deterrence model must be recognised as a clear advancement in the research field. Model comparison will always be context relative and a plurality of models should be viewed favourably. 相似文献

The United States’ Air Force (USAF) has developed and used unmanned aerial vehicle (UAV) technology to monitor and assassinate dangerous terrorists in Afghanistan, Iraq, Libya, Pakistan, Somalia, Syria, and Yemen. Currently, there are few countries that possess armed UAV and since the US created much of this technology, the USAF is usually part of the training that automatically accompanies the purchase of its UAVs. The research question this article attempts to answer is, “What is the extent of the United States’ Air Force assistance in the training and proliferation of UAV technology to foreign militaries?” 相似文献
