Some have argued that the transatlantic rancor over the Iraq war made cooperation, especially on nonproliferation, unlikely. In contrast, this article, documents post-invasion instances of nonproliferation cooperation, with particular emphasis on the Proliferation Security Initiative and the EU-3 Initiative—the British, French, and German negotiations with Iran over its suspected nuclear activities. In addition to documenting French and British participation in these initiatives, the article analyzes why they have chosen to participate and argues that France and Britain have participated in both efforts because they are committed to avoiding future Iraq-like preventive wars.  相似文献

THE NPT     
This article assesses the successes and failures of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) since its creation in 1968 by developing and applying a set of “metrics” to each of the NPT's substantive articles as well as to its withdrawal provisions. In light of this analysis, the article also puts forward some specific proposals for strengthening the NPT and its implementation, with a view to the debate and decisions at the upcoming 2010 NPT Review Conference. A concluding section turns explicitly to the 2010 NPT Review Conference and proposes pursuit of agreement on three NPT Action Plans: one for nonproliferation, one for peaceful uses, and one for nuclear disarmament. Combining vision and practicable steps, these Action Plans would set out a roadmap for action between the 2010 and the 2015 NPT Review Conferences. They could provide a foundation for substantive exchanges—in this case, on progress toward their implementation—during the preparations for the 2015 conference.  相似文献

ABSTRACT

Mexico’s defeat in the war that (in the U.S.) takes the country’s name resulted as much from the strategic context created by unrealized nation-building that followed independence as it did from American tactical supremacy. Three centuries of Spanish empire did not translate into national military excellence due to the decades of revolutionary upheaval that followed the sudden decapitation occasioned by Napoleon’s ouster of the monarchy in Madrid. That the occupation which followed major combat provided salutary lessons learned in dealing with guerrillas rather than a Vietnam-like litany of quagmire eventuated from the conscious designs of military leadership steeped in the same Napoleonic dynamic that had produced our opponent. The United States wisely chose to leave issues of state-building and governance to the Mexicans themselves, while annexing the sparsely populated northern remnant of Spanish empire.  相似文献

ABSTRACT

What Rudyard Kipling called the ‘campaign of lost footsteps’ was the longest campaign fought by the Victorian army. The conquest of Upper Burma, an area of 140,000 sq. miles with a population of four million, took only three weeks in November 1885 and was accomplished with minimum cost. However, the removal and deportation of the Burmese King and dismantling of all traditional authority dismantled led to growing resistance to British rule leading to an increasingly difficult guerrilla war. Though the Burmese guerrillas were characterised by the British as mere bandits or dacoits, many were former soldiers along with Buddhist monks. The extremely difficult nature of campaigning in the terrain and climate of Burma was not sufficiently appreciated by the War Office, who viewed the conflict as a ‘subaltern’s war’ and ‘police’ work. Intended regime change was also not accompanied by any consideration of the likely implications. Prolonged insurgency necessitated deploying a force far larger than originally intended; though order was finally secured by 1895, the campaign proved destructive of Burmese society while British recruitment of hill tribes into the police and armed forces sowed the seeds for future divisions.  相似文献

ABSTRACT

The United States’ global strategic outlook has shifted markedly since the end of major combat operations in Iraq and Afghanistan. As the United States’ strategic posture shifts, the nature of military operations is simultaneously changing rapidly. Many analysts predict that cyber-operations, autonomous weapons systems, artificial intelligence, and clandestine special forces operations will be central features in future conflicts. Although often overlooked by scholars and policy analysts, defence contractors are integral to the development and implementation of these emerging categories of warfare. This inquiry examines the evolving nature of the American defence industry and the roles corporations play in current theatres of conflict. Surprisingly, rather than becoming less reliant on defence contractors after their much-maligned performance in the wars in Iraq and Afghanistan, American military and intelligence agencies have become more dependent on the private sector as technology becomes increasingly central to warfare.  相似文献
