A NEW STANDARD FOR PREEMPTIVE MILITARY ACTION AGAINST WMD THREATS

International law clearly requires an imminent threat of attack as a justification for the preemptive use of military force. However, the standard definition of an imminent threat was derived centuries before the development of nuclear, chemical, or biological weapons or ballistic missiles and other delivery systems that can reach their targets in a matter of minutes. Any use of force to alleviate threats posed by weapons of mass destruction (WMD) prior to tactical warning of the actual launch of such weapons falls into the legally and ethically controversial category of “anticipatory self-defense,” leaving decision makers potentially liable to prosecution for war crimes. Effective and ethical enforcement of nonproliferation therefore demands a standard for imminence of threat broad enough to allow military action as a last resort but sufficiently restrictive to prohibit indiscriminate action against suspected WMD programs. Following a critical review of selected literature and cases on preemption, the author proposes a new standard for preemptive military action: the existence of operational WMD, or a clandestine program to develop WMD, in contravention of international law. The author discusses the implications of this new proposed standard, which at the time of writing would permit preemptive attack against WMD-armed terrorist groups but prohibit it against all states except Iran and possibly North Korea.

The United States has multiple nuclear detection initiatives to secure against a terrorist nuclear attack, including the Container Security Initiative, installation of radiation detectors at U.S. border points of entry, and establishment of the Domestic Nuclear Detection Office (DNDO). The current nuclear detection system architecture falls short of being able to reliably catch fissile nuclear material in transit, specifically shielded Highly Enriched Uranium (HEU) and Plutonium (Pu), both within the US and abroad. Checkpoints at border crossings can be circumvented, and no adequate system is under development to deter the transport of fissile materials. Using nuclear link-budget calculations, we show why a network relying primarily on handhelds, fixed detectors, and portals is not sufficient. We examine the technical, economic, and operational feasibility of a comprehensive national network incorporating in-vehicle detectors to reliably detect and deter the transport of fissile material inside the vehicle itself.

大气对流层气体组分随高度变化的理论预期

利用大气对流层温度随高度变化的规律,采用局部平衡的多分子混合模型,从理论上论证了对流层气体组分随高度变化的规律,发现大气各主要成分体积分数、分子平均摩尔质量均随高度线性变化,并拟合数值计算结果得到了相关参数。氧气的相对体积分数随高度明显下降,而氮气的相对体积分数却明显上升;但是相比于温度随高度的变化,大气分子平均摩尔质量的改变可以忽略。该理论比以往其他模型预测大气压强随高度变化规律具有更自然、更接近实际的优势。
