Theorizing about Taliban operations in Afghanistan has its limits and it is possible that Kabul-centric strategies do not adequately address the unique circumstances of each region in the country. How exactly has the Taliban gone about attaining its objectives in Kandahar province and how have those approaches evolved since 2002? And how have the Taliban adapted to coalition forces' attempts to compete with the insurgency and stamp it out? The answers to these questions are critical in the formulation of any counterinsurgency approach to Afghanistan.  相似文献

US foreign internal security assistance, that is, support to ‘Free World’ governments threatened by subversion, terrorism, and insurgency, formed a central part of the Kennedy administration's strategy for defeating ‘wars of national liberation’. As part of the administration's counterinsurgency policy, support to police and paramilitary forces abroad was intended to improve the ability of friendly governments to identify and root our perceived threats to the states. Under the tenets of modernization theory embraced by administration officials, strong internal security forces were expected to contribute to nation-building by protecting the fragile development process underway in the developing world. However, in attempting to export the American police model, policymakers failed to consider whether US notions about internal security were appropriate for fractious and unstable regions of the world.  相似文献

Over the past several decades, NATO allies have debated the relative burdens and benefits of NATO membership. Recently, this concern surfaced as members debated the magnitude and distribution of NATO expansion costs. This paper presents an economic model of defence alliances to identify the benefits and burdens of alliance membership. It suggests that defence expenditures provide public benefits if alliance members share common interests and mutual commitment; defence expenditures provide private benefits if countries lack common interests and mutual commitment. The model's results are used to discuss NATO's evolving roles and missions, NATO expansion and burden sharing across NATO members.  相似文献

BUSTING OUT     
This report explores Iranian popular opinion on the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and the determinants of Iranian attitudes. Using data from a 2008 survey of 710 Iranians administered by the University of Maryland's Program on International Policy Attitudes, we find that that a significant minority of Iranians (10 percent in 2006 and 14 percent in 2008) would prefer that Iran withdraw from the NPT. Our statistical analysis shows that Iranians who fear a US attack on Iranian nuclear facilities and distrust the International Atomic Energy Agency are more likely to want to quit the NPT. We therefore argue that those who do not trust other nations are most likely to oppose the NPT.  相似文献

An increasing number of countries recognize the special risks of nuclear terrorism associated with the civilian use and storage of and commerce in highly enriched uranium (HEU). They are especially concerned that non-state actors might gain access to HEU and use it to build and detonate improvised nuclear devices. The risk is aggravated by the very large global stocks of HEU, some of which are inadequately protected. Although HEU has few commercial uses, and most experts believe it is technically feasible to substitute low-enriched uranium for HEU in nearly all civilian applications, efforts to reduce HEU stocks have been impeded by a variety of economic, political, and strategic considerations. This article analyzes the nature of these impediments and discusses what is required to overcome them.  相似文献

This article addresses the problem of scheduling the United States Navy's Atlantic Fleet to satisfy overseas strategic requirements. An integer programming formulation is developed but results in a model with prohibitive size. This fact and the qualitative nature of additional secondary objectives and constraints suggest an interactive optimization approach. A system that solves a natural relaxation of the integer program within an interactive environment is discussed.  相似文献
