The U.S. Congress, charged with overseeing U.S. nuclear weapons policy and programs, usually addresses such policies and programs through the annual authorization and appropriations process, focusing mostly on questions of how many and what types of weapons the United States should deploy, with little attention paid to questions about nuclear weapons strategy, doctrine, and policy. The oversight process has brought about some significant changes in the plans for U.S. nuclear weapons, including the elimination of funding for the Robust Nuclear Earth Penetrator study and the shift of that funding into a study of the Reliable Replacement Warhead. But with the focus on authorizations and appropriations, along with the divided jurisdiction over nuclear weapons policy and programs in congressional committees, Congress has not, either recently or during the Cold War and post–Cold War eras, conducted a more comprehensive review of U.S. nuclear weapons strategy, policy, or force structure. Changes in committee jurisdictions could affect the oversight process, but as long as nuclear weapons policy and programs remain a relatively low priority for most members of Congress, and the country at large, it is unlikely that Congress will pursue such a comprehensive debate.  相似文献

This viewpoint takes stock of the changes in the strategic nuclear landscape in recent decades and reflects on its consequences on the policy community. It finds that the number and scope of issues have expanded considerably; they have manifested themselves in many more regions of the world; and they have become deeply politicized and polarized. The consequences have been twofold: the nuclear policy field has seen the development of an increasingly diverse expert community composed of highly specialized functionalists and regionalists, and it has become ever more divided into two entirely separate ideological camps—one that believes in deterrence, the other in disarmament. The stove-piping of expertise and the widening gap between deterrence and disarmament ideologies are immensely problematic because, in different ways, they stand in the way of the emergence of a better and safer nuclear future. Looking ahead, it is critical to “bust the silos of expertise” and to build bridges between the deterrence and disarmament ideological camps. Only such a community-building effort will help solve today’s and tomorrow’s nuclear challenges.  相似文献

ABSTRACT

Decade-long security cooperation and counterterrorism engagements in Nigeria have failed to bring down Boko Haram or at least weaken its terrorist structures and transnational spread. I argue that disconnects between counterterrorism-assistance seeking states and their superpower sponsors are implicated in the intractability of Boko Haram's insurgency in Nigeria. Why is the U.S. counterterrorism intervention to individual MNJTF countries (i.e. troop contribution, military funding and intelligence support) ‘lopsided’, ‘fragmented’ and ‘unevenly distributed;’ and how are these implicated in the fight against Boko Haram terrorism? This has impacted negatively on MNJTF countries – lack of cooperation, divisiveness and individualism in coordinating and forging offensives against Boko Haram. These concerns interface several blind spots in the picture of external influences on military’s approach to Boko Haram. I elicit primary data from top military officers. I conclude by predicting the implications and consequences of these counterterrorism complexities, and their potency to defeat or encourage Boko Haram terror.  相似文献

This article presents a synopsis of Community of insecurity: SADC's struggle for peace and security in southern Africa, published by Ashgate in 2012. It focuses on SADC's efforts to establish a common security regime; conflict and peacemaking in southern Africa between 1992 and 2011; and the prospects of SADC becoming a security community. It summarises the reasons for SADC's difficulties in the sphere of regional security and politics, namely the weakness of member states, their unwillingness to surrender sovereignty to communal mechanisms, and the absence of common values among them. The main conclusion is that these problems lie primarily at the national level and cannot be solved at the regional level. SADC is a forum of states and it cannot do anything that these states will not permit it to do.  相似文献

In June 2000, the Conference of Heads of State and Government of the Economic Community of Central African States (ECCAS) adopted the Protocol on the establishment of the Peace and Security Council for Central Africa (COPAX), with its two technical structures, namely the Central African Multinational Force (FOMAC) and the Central African Early Warning Mechanism (MARAC). MARAC is tasked with collecting and analysing data for the early detection and prevention of conflicts and crises. It currently consists of the Central Structure located at the ECCAS Executive Secretariat in Libreville (Gabon) and 31 Decentralised Correspondents spread throughout the ten member states of ECCAS. This article assesses the performance of MARAC in the light of its assigned objectives. Bearing in mind the peace and security challenges facing the central African sub-region, the central argument of this article is that while the establishment of MARAC is commendable, it flowed more from the logic and context of the establishment of similar mechanisms on the African continent during the same period than from any displayed capacity and/or readiness on the part of ECCAS to implement the recommendations due to emanate from such a structure.  相似文献

ABSTRACT

Natural resource-based conflicts continue to occur in different parts of Nigeria with negative implications. This study investigated the phenomena of natural resource conflicts vis-à-vis their propensities to impact political economy and national security negatively. Data for the study were sourced from theoretical and empirical evidence. Empirical data were sourced from existing studies selected on the basis on their relevance to the study and analysed based on their content. The limitation to this approach is the obsolete and subjective nature of some the literature. This limitation was, however, addressed among others through the author’s knowledge of the issues under study. The study found that Nigeria is enmeshed in conflict over ownership, distribution, access to or competition over natural resources such as petroleum resources and agricultural land and these conflicts have undermined democracy, human rights, the economy and the nation’s security. The paper identified poor resource governance, environmental factors and poor political leadership as the causes and drivers of these conflicts. It recommends natural resource governance among others, as a way out of the problem.  相似文献

Current U.S. nuclear weapons strategy, force structure, and doctrine contribute to the threat of nuclear terrorism in several ways. First, the U.S. nuclear stockpile presents opportunities for nuclear terrorists to seize the materials they need. Second, U.S. nuclear forces remain a key justification for Russia's maintenance of similar nuclear forces that are less well protected. Third, America's continued embrace of nuclear weapons encourages and legitimizes other states to seek nuclear weapons that they will have difficulty securing from terrorists. The national security interests of the United States would be better served by a strategy to shrink the global footprint of nuclear weapons and provide the highest possible levels of security for the most minimal possible deterrent forces. Given the inability to secure nuclear weapons and materials perfectly or to eliminate terrorism in the foreseeable future, reducing the global inventory of nuclear weapons and materials is the most reliable way to reduce the chances of nuclear terrorism.  相似文献

This paper is intended to complement the existing literature on civil wars. First, it presents a simple theoretical model of conflict that defines a two‐sector economy. In a contested sector, two agents struggle to appropriate the maximum possible fraction of a contestable output. In an uncontested sector, they hold secure property rights over the production of some goods. Agents split their resource endowment between ‘butter’, ‘guns’ and ‘ice‐cream’. Following the theoretical insights the empirical analysis focuses on the relationship between civil wars and different sectors of the economy. In particular, a panel probit specification shows that the incidence of a civil war decreases in the size of manufacturing sector.  相似文献
