Given the long history of US state crimes related to nuclear weapons and the aggressive unilateralism of the George W. Bush administration that compounded these crimes, the election of Barack Obama created a “hope” for “change” in American nuclear weapons policy. While it is too early to render any conclusive judgment, we offer a preliminary assessment of the Obama record with regard to nuclear weapons based on a number of significant policy statements made and official actions taken, including Obama's 2009 Prague speech, the signing of the new START agreement in April 2010, the administration's 2010 Nuclear Posture Review, the Washington DC Nuclear Security Summit, and the Nuclear Nonproliferation Treaty Review Conference of 2010. Although the new administration has taken some steps to reduce the likelihood of the use or threat to use nuclear weapons, we conclude that under President Obama the US continues to be in violation of the solemn legal obligation to disarm as imposed by the NPT treaty of 1968. We also briefly note some of the structural and cultural factors related to the American empire that hinders any president from changing American nuclear weapons policy. 相似文献

A scheduled conference to promote a zone free of weapons of mass destruction in the Middle East has renewed hopes for nuclear disarmament in this unstable region, if only innovative diplomacy could take advantage of the current shifts. However, a realistic assessment suggests that optimism is unwarranted. Fundamental strategic considerations related to Iran's nuclear program, Israel's atomic options, and the region's ingrate security architecture remain nearly insurmountable hurdles. Therefore, policymakers should focus first on attaining a resolution of the Israeli-Palestinian conflict. 相似文献

Abstract Within the next few years, NATO will need to make a collective decision about the future of US tactical nuclear weapons (TNW) in Europe. While opinion about the value of these weapons is not as split as conventional wisdom might suggest, and while NATO will remain a nuclear alliance irrespective of this decision, balancing politics and strategy looks likely to be a difficult task. This decision is made far more complex by the determination of NATO officials to link the withdrawal of these weapons to reciprocal reductions in Russian TNW in Europe, and by the possibility of substituting the key strategic and political link they provide with a ballistic missile defense (BMD) system. This article shows how we have arrived at this position, highlights the potential benefits to NATO Europe of BMD, and considers the key questions that the Alliance will face in achieving this. Ultimately, this article shows how the future of TNW in Europe is likely to be linked to whether NATO values arms cuts with Russia, or the deployment of missile defenses, as its central priority. 相似文献

Abstract The New Strategic arms reduction treaty nuclear arms control agreement signed by US President, Barack Obama, and Russian President, Dmitry Medvedev, in 2010 is likely to achieve ratification in both Washington and Moscow, but it is too early to break out the champagne or vodka. Even successful ratification of this agreement is, at best, an important but incremental part of the US–Russian policy ‘reset’ and the larger agenda for both states with respect to arms reduction and nonproliferation. Further reductions in both states’ inventories of strategic nuclear weapons are a necessary preface toward credible leadership in stopping the spread of nuclear arms – especially in the looming test cases of Iran and North Korea. In addition, both states have to decipher a policy-strategy nexus for emerging missile defense technologies: in particular, whether missile defenses should be seen as possible means of cooperative security, as between NATO and Russia, or whether they are firewalls in the way of further progress in offensive nuclear arms reductions. 相似文献

Abstract Northeast Asia is notable for the relative absence of regional institutions. The Six Party Talks could constitute an embryonic starting point for the development of such institutions. The path toward greater institutionalization is likely to begin in a modest fashion. Functional working groups on topics such as the environment, maritime transport, technical barriers to trade, road and rail links, and energy could provide the locus for integrating North Korea into the broader regional and global economies. Foreign ministries will inevitably take the lead in developing the Northeast Asia Peace and Security Mechanism (NEAPSM), but meaningful economic achievements will require the involvement of other ministries. North Korea has proved problematic in this regard thus far. Moreover, given the importance of private-sector involvement in achieving sustainable economic development in North Korea, modalities will have to be developed to integrate private-sector actors when possible. The governments of the region, and particularly China and South Korea, may continue support on a bilateral basis as a hedge against North Korea's collapse or as inducements in the context of the nuclear talks. But the development of more permanent multilateral structures is unlikely until the nuclear issue is resolved. 相似文献

ABSTRACTCivil society research can be categorized into a school in the tradition of Gramsci focusing on social movements and a Tocquevillean school focusing on associations and social capital. The author reviews both schools’ research on the Japanese case and analyses a number of pro-nuclear citizen groups built up by the Japanese nuclear industry. The author analyses their financial data and historical development to demonstrate that they have been built up as countermovement by the nuclear industry. The author traces their mobilization processes to criticize the social capital approach. In Japanese political science, traditionally a dense web of hierarchical associations and ties of obligation have been seen as enforcing clientelism and top-down political control. This makes Japan an interesting case for the social capital approach. Social capital researchers have reinterpreted hierarchical networks as indicators of a strong civil society. Taking into account Bourdieu’s notion of social capital challenges this view and supports arguments of state influence forwarded by parts of the Gramscian school. 相似文献

This study examined the cellular origin and concentration of nuclear DNA in human urine. Ten subjects provided two entire, first-morning voids: one as a single specimen and one as a consecutive series of samples. The serial samples were centrifuged, organically extracted, and quantified by slot-blot analysis. Total DNA concentrations ranged from 0.02 to 21.3 ng/mL for the males and 25.0 to 96.9 ng/mL for the females. The female samples were found to contain numerous vaginal epithelial cells. DNA was detected in all of the serial samples of nine subjects; however, the DNA concentrations varied considerably. With six subjects, the DNA concentration of the first serial sample was at least three times greater than that of the entire void. DNA was only detected in the first 21% of the void from one male subject. The results of this study have implications for the collection of urine samples. 相似文献

Online vendors are offering a new legal high, 4‐methylpentedrone (4‐MPD). Information for potential users provided by internet vendors of 4‐MPD includes incorrect structures and nonexistent CAS numbers. A sample of 4‐MPD was obtained and analyzed using GC‐MS, NMR, and LC‐EIS. The fragmentation data from the GC‐MS and LC‐EIS produced an M‐1 ion that suggested the molecular mass was 219 amu, rather than 205 amu as calculated for 4‐methylpentedrone. The difference in molecular mass corresponded to the addition of a methyl group. Based on the mass and fragmentation pattern, two standards were synthesized, 2‐(ethylamino)‐1‐(4‐methylphenyl)‐1‐pentanone and 1‐(4‐methylphenyl)‐2‐(propylamino)‐1‐butanone. The synthesis involved bromination of the appropriate ketone followed by the reaction with ethylamine or propylamine. Based on the NMR data and unique fragmentation patterns produced by these molecules, the sample was identified as 2‐(ethylamino)‐1‐(4‐methylphenyl)‐1‐pentanone, not 4‐methylpentedrone. 相似文献
