While unmanned aerial vehicles (UAVs) have become a standard element of modern armed forces, African countries have been reluctant to acquire remotely piloted aircraft for military purposes until recently. This is mainly due to a lack of industrial capabilities and, for military purposes so far, procurement policies that have concentrated on small arms and light weapons, more prestigious armoured vehicles and combat aircraft. Moreover, counter-insurgency strategies in Africa tend to focus on manoeuvre warfare, co-opting rebels or fighting them using armed proxies. As a consequence, international counterterrorism operations against fanatical and reckless groups like al-Qaeda in the Islamic Maghreb and Boko Haram in sub-Saharan Africa are characterised by a strong dependence on Western forces providing UAV-based reconnaissance and, in some cases for the United States, military strikes by drones. This essay reviews some of the incentives and problems of the use of UAVs in the African context. Given the geographical and military conditions of asymmetric warfare in Africa, and potential problems concerning international law, ethical aspects of the use of arms, and civil–military relations notwithstanding, it is argued that African security forces should develop their own UAV capabilities by intensifying their cooperation with Western armed forces. 相似文献

Stability among the great powers during the Cold War is widely theorized in terms of nuclear deterrence. Rationality of States and their preference for survival are the basis of nuclear deterrence. The rationality of non-state terrorist groups is different from that of nation-states. Even though they are also rational actors with their own hierarchy of preferences, survival may not be their ultimate goal. Deterrence of nuclear terrorism is therefore different from deterrence against states. South Asia is more vulnerable to nuclear terrorism than any other region of the world for many reasons. This article analyzes the possibility of nuclear terrorism and the ways of deterrence against it in the context of South Asia. 相似文献

In this paper, we study the domestic political determinants of military spending. Our conceptual framework suggests that power distribution over local and central governments influences the government provision of national public goods, in our context, military expenditure. Drawing on a large cross-country panel, we demonstrate that having local elections will decrease a country’s military expenditure markedly, controlling for other political and economic variables. According to our preferred estimates, a country’s military expenditure is on average 20% lower if its state government officials are locally elected, which is consistent with our theoretical prediction. 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

2016年年初以来,朝鲜先后进行了第四次、第五次核试验,在此背景下,韩国国防部宣布,韩美同意在韩国部署末段高空区域防御系统——\"萨德\"导弹防御系统,朝鲜半岛地区风云再起。美韩此举使原本不安的东北亚局势更加紧张,诱发并恶化着东北亚地区大国家间潜存的\"安全困境\"。韩国决定部署\"萨德\"不仅严重僵化了中韩的国际关系,使得原本对峙局面下的朝韩两国局势更加紧张,更破坏了东北亚军事战略均衡,地区\"新冷战\"格局逐步形成。 相似文献

Pakistan, the fastest growing nuclear weapon state in the world, has established over the last decade a nuclear management system it holds to be “foolproof.” Despite the explosion of radical groups challenging the writ of the state, it dismisses concerns by critics that its nuclear weapons are not safe and secure as “preposterous” and an attempt to “malign” the state. This article examines Pakistan's nuclear management system in four functional areas: command-and-control, physical security, nuclear surety, and doctrine. It describes what is publicly known in each area, identifies areas of omission and inadequacy in each one, and examines several premises of the nuclear program the author considers to be unfounded. Comparing these deficiencies in Pakistan's nuclear management system to the current problems plaguing the US nuclear management system, the author concludes that complacency and unfounded confidence in the efficacy of such programs, if not addressed and corrected, could lead to a future nuclear catastrophe in South Asia. 相似文献

The drone is the latest tool to promote interests of a nation-state. It is clear that USA as well as other major powers anticipate that robotics will play a key role in future warfare. Today, more than 70 countries have already acquired drone technology and many others are desperate to join the ranks. This urge for drone technology will ultimately lead to a “boundless and borderless war without end.” In the case of Pakistan, the US drone campaign has raised some important issues regarding how their use could, or should, be regulated in the future. This article analyses the legal issues raised by the US's use of drone technology in non-combat zones, such as Pakistan. It is argued that a reckless disrespect of Pakistan's sovereignty has had adverse implications and consequences for the legitimacy of the Pakistani government. Drone strikes have prompted instinctive opposition among the Pakistani population, hurt their feelings and estranged them from the government. This in turn has added to Pakistan's instability and stimulated a ground-swell of animosity toward the USA. 相似文献
