After the conclusion of the 2008 Preparatory Committee (PrepCom) for the 2010 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Nonproliferation Review interviewed Ambassador Yukiya Amano of Japan, who presided over the 2007 session of the PrepCom in Vienna. He provided valuable insights into his preparations for the PrepCom and shared his thoughts on some of the most pressing issues that confronted his chairmanship and the PrepCom as a whole. The interview also provides useful perspectives on the future of the strengthened review process. 相似文献

Adopting the analytical framework of the established interpretive “schools” of Anglo-American relations, this article offers several reflections on UK–US defense relations as they occurred over the significant years of 2000–2005. During those years, trajectories were established on which UK–US defense relations continue to travel today and outcomes emerged which are still being navigated. This article concludes that the Latin phrase, “Flectas Non Frangas” (essentially translated as: “Bend not Break”), is the most appropriate to adopt to characterize the developments undergone in recent UK–US defense relations. Many historical and strategic lessons with contemporary relevance are drawn. 相似文献

In an important and stimulating article, Stephan Frühling and Andrew O’Neil argue in favor of applying institutionalist theory to understand the alliance politics of U.S. nuclear weapons strategy. But what promise does institutionalist theory really hold in thinking about highly unequal alliances nested in their particular threat environments? I argue that much work remains to be done to determine how much better institutionalist variables explain intra-alliance dynamics over alternative arguments that emphasize power and interests. Balances of power and the nature of threat environments may already account for key aspects of extended deterrent relationships supported by the United States in Europe and Asia. Ironically, the implication of this more traditional interpretation of alliances is that more continuity than change will characterize how Donald Trump will manage U.S. security relationships as President. 相似文献

Deterioration in security relations as between NATO and Russia reached boiling point in the aftermath of Russia’s annexation of Crimea in 2014 and its subsequent destabilization of Eastern Ukraine. As a result, some voices in the West look forward to the departure of Vladimir Putin from power, and others to the possible disintegration of Russia as a unitary state. However, both the departure of Putin and the collapse of Russia have a nuclear dimension. Putin has issued pointed reminders of Russia’s status as a nuclear great power, and Russian military doctrine allows for nuclear first use in the event of a conventional war with extremely high stakes. Beyond Putin, a breakup of Russia would leave political chaos in Eastern Europe, Central Asia and elsewhere, inviting ambiguous command and control over formerly Russian nuclear forces. 相似文献
