Property distribution and configurations of sovereign states: A rational economic model

A nation's wealth is both an object of conquest to covetous aggressors and a resource to its owners for self defense. To maintain autonomy every country must mount a defense which either makes its capture (1) more expensive than any aggressor can afford, or (2) more expensive than it is worth to aggressors. Whether this condition can be satisfied for all countries simultaneously depends as shown in this paper on relative efficacy of military offense versus defense, the aggregate of wealth among nations and its distribution, and the benefits a conqueror may obtain from conquest, including the duration of these benefits. The paper shows how these factors fit together to determine the sustainability and stability of the international distribution of property as embodied in the configuration of sovereign states.     

Models of scientific and technological review for the Biological and Toxin Weapons Convention

ABSTRACT

Science and technology (S&T) review is key to anticipating developments in the life sciences that may benefit or run contrary to the aims of the 1972 Biological and Toxin Weapons Convention. It serves as a mechanism for both preparing against novel biological threats and identifying the best opportunities for developing and sharing the life sciences to the fullest extent. In the age of rapidly advancing biotechnology, S&T review needs to be wide ranging, involve a diverse set of inputs, and be transparent about its methods and data. This viewpoint considers four models of S&T review and their capacity to respond to the challenge of the life sciences: standing advisory boards; ad hoc working groups; peer review; and wikis. It then identifies a hybrid model that is suitably broad, diverse, and transparent.     

The Power of the NPT: International Norms and Ukraine's Nuclear Disarmament

ABSTRACT

There is a lingering disagreement among scholars on how the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) affects nonproliferation and disarmament outcomes. Drawing on constructivist scholarship on international norms, this article examines the extent of the NPT's effect in the case of Ukraine's nuclear disarmament. In the wake of the Soviet Union's collapse, Ukraine found itself host to the world's third largest nuclear arsenal. Despite Ukraine's initial commitment to become a non-nuclear state, it proceeded along a difficult path toward NPT accession. Most controversial and directly at odds with the NPT was Ukraine's claim to ownership of its nuclear inheritance as a successor state of the Soviet Union. This article argues that, while much domestic discourse about the fate of these nuclear weapons was embedded in the negotiation of Ukraine's new identity as a sovereign state vis-à-vis Russia and the West, the NPT played an important, structural role by outlining a separate normative space for nuclear weapons and providing the grammar of denuclearization with which Ukraine's decision makers had to grapple.     

NUCLEAR PROLIFERATION

As the potential for the involvement of corporations in the manufacture of nuclear weapons has increased, particularly through dual-use technology, global regulation has failed to keep pace. Where regulation of private corporations does exist, in the form of treaties, UN resolutions, or more informal arrangements, the obligations fall only on states. This state of affairs is a result of international law's traditional deference to state sovereignty; yet, it has led to significant shortcomings in the global regulatory regime, where states are unwilling or unable to meet their obligations. While radical departures from the traditional model of international law might remove the regulatory gaps caused by noncompliant states, such changes are unrealistic in the current political climate. More realistic changes must be focused on, offering greater recognition of the role of private corporations in nuclear proliferation and increasing state compliance with existing regulation.     

Home-Grown Fighting: A Response to the Argument for a Byzantine Influence on MS I.33

Abstract

In an earlier issue, Dr. Timothy Dawson suggested that the fighting techniques found in Royal Armouries MS I.33 may have been influenced by earlier Byzantine sword and shield combat. For evidence, he cites a series of 9th-century ivory carvings depicting similar positions found in I.33. This article is a response to Dr. Dawson’s, in which it is argued that there is ample evidence for similar combat positions being found in Western Europe that both pre-date and are contemporary with I.33.

信息化条件下的军备控制

军备控制的目的是维护国家的安全和减少国家安全威胁.随着现代科学技术的发展和世界经济一体化进程的加快,国家安全威胁的因素与国家军事能力同步增长.尤其是现代信息技术的快速渗透和发展,不仅带来了安全隐患的增加,也加速了武器装备的更新换代,对国际军备控制产生了广泛的影响.     

From the Editors

Israel's policy of military reprisals has never seemed to follow any consistent pattern of tit‐for‐tat. On the one hand, not every violent incident was answered with a counterattack. On the other hand, when Israel responded, frequently it employed an excessive amount of force, which was disproportional to the Arab provocation. This behavior has not been the consequence of a premeditated and rational strategy. Instead, it appears to have been the result of a political dispute between alternative approaches regarding the use of military force. The following research analyzes the development of this controversy and how these differences of opinion were resolved.
