Drawing on evidence collected from eyewitness interviews, new Russian secondary sources, as well as recently declassified documents from both sides, the author significantly widens the academic understanding of the maritime dimension of this gravest crisis of the Cold War. Most significant is her conclusion that Soviet commanders were led by complex and challenging tactical circumstances, including unreliable communications and malfunctioning equipment, which might have prompted them to contemplate a resort to tactical nuclear weapons on more than one occasion. Almost as disturbing is the revelation that US forces were not aware of this particular threat. This research reveals how a chain of inadvertent developments at sea could have precipitated global nuclear war, underlining the extreme danger of the crisis.  相似文献

ABSTRACT

The present international standard allows non-nuclear weapon states (NNWS) to forego safeguards when nuclear material is used in a “non-proscribed military activity,” though no criteria have been established to determine when NNWS can remove naval nuclear material from safeguards. Though at present, only nuclear-armed states possess nuclear submarines, the global nuclear naval landscape may soon change with the advancement of Brazil's fledgling program and the possible precedent it would set for other NNWS. A framework is needed to shore up nuclear security and prevent nuclear material diversion from the nuclear naval sector. Proposed and existing nonproliferation frameworks, including a Fissile Material Cut-off Treaty and commitments through the nuclear security summits, are insufficient to close this loophole. A Naval Use Safeguards Agreement (NUSA), modeled after the Additional Protocol of the International Atomic Energy Agency, would provide a framework to remove the opacity surrounding nuclear material in the naval sector. Designed for NNWS and encouraged as confidence-building measures for nuclear weapon states, NUSA would explicitly outline those stages in the naval nuclear fuel cycle where safeguards are to be applied and in what context. This viewpoint also further provides direction for targeted research and development in technical naval nuclear safeguards solutions.  相似文献

Nicholas John Spykman was probably America’s finest geopolitical theorist of the twentieth century, even though he was an active participant over the course only of five years (1938–43). He is rightly viewed as a worthy intellectual successor to Sir Halford Mackinder in Britain. Spykman originated the (Eurasian) Rimland concept, which is of continuing political and strategic utility today. He was controversial and notably outspoken while his writings make it quite clear that his concern with the acquisition of power was contextualised by serious concerns for world order.  相似文献

In this paper we change the structure of the basic conflict model. This makes it possible to found an economic theory of war and peace. Apart from few exceptions there exist no peace equilibria in the related literature of conflict theory. The aim of the paper is to fill this gap, because most parts of the world live in peace. Further we show that negotiations are possible to avoid a war. The main result is that war breaks out only if the distribution of resources and/or the effectiveness of weapons is sufficiently unequal.  相似文献

We address empirically the question of why international economic sanctions are, or are not, chosen as instruments of foreign policy and the question of what determines their success. We hypothesize that cultural linkages between nations are an important factor in explaining both instrument choice and conflict outcomes. Countries that share significant cultural attributes are found to be less likely to apply economic sanctions against one another than countries lacking such cultural ties. However, it is precisely in the case of culturally similar sender and target nations that sanctions are most likely to succeed.  相似文献

We look at the different ways of aggregating the exports of dual use products to give the security perception of exporter countries and their consistency with the relevant export control regimes. Also, we analyze different models of export controls highlighting the role of the perception of security, market structure and competition between exporting firms in determining the existence of multiple equilibria and therefore, the need for coordination between countries in setting export controls.  相似文献

ABSTRACT

Researchers have recently proposed a new approach to nuclear-arms-control verification, dubbed “deferred verification.” The concept forgoes inspections at sensitive nuclear sites and of nuclear weapons or components in classified form. To implement this concept, a state first divides its nuclear program into a closed segment and an open segment. The total fissile-material inventory in the closed segment, which includes the weapon complex, is known and declared with very high accuracy. Essentially no inspections take place in the closed segment. In contrast, inspectors have access to the open segment, which includes in particular the civilian nuclear sector. The fissile-material inventory in the open segment is known with less accuracy, but uncertainties can be reduced over time using nuclear-archaeology methods. Deferred verification relies primarily on established safeguards techniques and avoids many unresolved verification challenges, such as the need for information barriers for warhead confirmation measurements. At the same time, deferred verification faces some unique challenges. Here, we explore some of these challenges and offer possible solutions; to do so, we examine possible noncompliance strategies in which a state would seek to withhold a higher-than-declared inventory.  相似文献

International Atomic Energy Agency (IAEA) safeguards are under more stress today than at any time in their history. Compliance concerns, a shortage of resources and technology, and growing responsibilities threaten to undermine the effectiveness and credibility of this vital and fundamental pillar of the nonproliferation regime. To address this challenge, the United States recently launched the Next Generation Safeguards Initiative. The goal of this initiative is to ensure the IAEA makes the fullest possible use of its existing authority to prevent the diversion of safeguarded material and to investigate suspicious activities. The initiative will advance state-of-the-art technology, foster the development of a new generation of safeguards experts, and promote technology collaborations and safeguards-conscious infrastructure in states using or pursuing nuclear power. Although it has a domestic focus, the initiative's intent is to catalyze a much broader commitment to international safeguards in partnership with other governments and the IAEA.  相似文献

Abstract

The Sword of Honour (RA IX.1841) presented in 1856 by the Province of Nova Scotia to its native son, General Sir William Fenwick Williams, Bart. for his deeds at Kars, Turkey, is described, illustrated, discussed and placed both in its historical and its design context. Other notable British swords of the Victorian Age (1837–1901), the Age of Empire, are also examined and the various and influential aspects of their designs, ornament and iconography discussed.  相似文献
