THE MYTH OF NUCLEAR DETERRENCE

Nuclear deterrence is sometimes treated as a known quantity—a definite thing that keeps us safe and ensures our security. It has also often been used as a justification for possessing nuclear weapons. Nuclear deterrence, however, is based on an unexamined notion: the belief that the threat to destroy cities provides decisive leverage. An examination of history (including recent reinterpretations of the bombing of Hiroshima) shows that destroying cities rarely affects the outcome of wars. How is it possible that an action that is unlikely to be decisive can make an effective threat? Recent work on terrorism suggests that attacks against civilians are often not only ineffective but also counterproductive. And a review of the practical record of nuclear deterrence shows more obvious failures than obvious successes. Given this, the record of nuclear deterrence is far more problematic than most people assume. If no stronger rationale for keeping these dangerous weapons can be contrived, perhaps they should be banned.

On the Road to the 2015 NPT Review Conference

The second session of the Preparatory Committee for the 2015 Review Conference (RevCon) of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) highlighted two issues in particular—progress toward a Middle East Weapons of Mass Destruction–Free Zone and the Joint Statement on the humanitarian impact of nuclear weapons—that may not only greatly affect the health and vitality of the NPT and the 2015 RevCon, but possibly also have implications for the international nonproliferation regime as a whole. Dr. William Potter, director of the James Martin Center for Nonproliferation Studies, interviewed Ambassador Cornel Feruta, chairman of the 2013 PrepCom, to discuss these and other issues related to the meeting and the future of the treaty and its review process.     

The Moral Dimension of “Global Zero”

Regrettably, moral arguments are largely absent from the current debate on nuclear disarmament. Indeed, complementing politico-strategic thinking with ethical categories could significantly strengthen the abolitionist call. To fill the gap, this article analyzes the evolution of the nuclear ethics of the Roman Catholic Church and especially its position on nuclear deterrence. If this strategy was granted interim and strictly conditioned moral acceptance during the Cold War, nuclear deterrence is today increasingly considered ineffective, an obstacle to genuine disarmament, and hence morally unjustifiable. In the new security context, the conditions for the Catholic Church's “interim nuclear ethics” have altered, and nuclear disarmament has become a feasible option and an alternative strategy to deterrence.     

边坡稳定性理论及其局限性

边坡分析理论经过近几十年的发展,基本形成了完善的体系。较为典型的有 极限平衡法,极限分析法,有限元法等。对各种分析方法做了简要的回顾与评述。基于极限 平衡原理发展的各种分析方法,大多需要做许多假设,同时对岩质边坡又不能很好地考虑其 断层节理特征。有限元强度折减法,是近年来发展起来的一种分析方法,与极限平衡法相比 不需要任何假设,可以求得任意形状边坡的临界滑移面及其对应的安全系数,同时可以反映 边坡失稳及塑性区的发展过程,为岩土体边坡分析开辟了新的途径。
