The next American president will face a daunting list of national security problems, including a serious defense budget crunch. The budget crisis will be deepened by the global financial crisis, a tapering of supplemental funding associated with the wars in Iraq and Afghanistan, and the steady growth of military healthcare and other personnel costs. After six years of rapid defense budget increases, the Pentagon has lost the practice of matching strategy and resources. The next president will need to manage risk among investments in irregular warfare, counterterrorism, balancing new super powers, countering weapons of mass destruction, and traditional warfare. He will also need to begin to build non-military “soft power” capabilities outside of the Pentagon. 相似文献

In this paper, we introduce relative-payoff maximizing firms into the Tullock model of rent-seeking. These firms try to realize higher (expected) payoff than other firms. As a consequence of this, the outcome of the model changes: Firms, on average, will invest more in the rent-seeking process, the rate of dissipation of the rent becomes independent of the number of rent-seekers, dissipation becomes complete in cases where underdissipation prevails in the original model. 相似文献

This article assesses the British military effort in Afghanistan looking at three key elements in the campaign: strategy, military operations, and the inter-agency “Comprehensive Approach.” We start by recognising the scale of the challenge that has faced the British: of all the provinces in Afghanistan, Helmand is the toughest to stabilize and secure. We then examine the evolution of all three elements above and find significant improvements in each: a flawed strategy has been corrected; the military have received more resources and become significantly better at COIN; and there is significant progress in the development of the inter-agency approach. In short, what the Americans will find in Helmand is a British COIN machine; a little creaky perhaps, but one that is fit for purpose and getting the job done. We briefly conclude on the prospects and the key to success: namely the development of a more coherent international strategy that accommodates the challenges posed by both Afghanistan and Pakistan. 相似文献

For half a century the study of civil-military relations has focused on the problem of civilian control, with Huntington's objective control concept supported as the optimal solution not only for civilian control in peacetime but also for military success in war. The challenges of modern warfare suggest the need for a new problématique founded upon the essential need for accuracy in pre-war net assessments. Inaccurate pre-war assessments, rather than a purported dearth of objective control or ‘derelictions of duty,’ explain many problems with recent war efforts. Furthermore, accurate pre-war assessments are hindered by objective control arrangements. An alternative approach of Open Debate among civilian and military leaders, would, in the pre-war period, acknowledge the need for high-level discussion of non-politicized expertise from multiple institutions. Open Debate would require altering institutional arrangements as well as the education of public servants. 相似文献
