Nuclear Issues

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

"In Bargaining on Nuclear Tests the historian Or Rabinowitz demonstrates the rare ability to engage with contemporary policy debates on nuclear proliferation and U.S. nonproliferation strategies on the one hand, and successfully utilize qualitative analytical frameworks in social science like prospect theory (19) on the other."

Scholars have argued that acquiring nuclear weapons should allow states the luxury of exiting conventional arms races. In turn, a decreased budgetary focus on conventional arms should make possible greater spending on social welfare. The author contests this logic of nuclear substitution by examining its most likely exponent, Pakistan. As a poor, underdeveloped state, a nuclear Pakistan should have welcomed the opportunity to cease its arms race with India, and spend greater sums on its population's welfare. Instead, the article shows that Pakistan has doubled down on its pre-nuclear conventional posture, mainly because of its revisionism over Kashmir.

Pakistan has developed tactical nuclear weapons to deter India from executing its Cold Start war doctrine. India, however, has disavowed that doctrine. Further, the use of such weapons against Indian troops inside Pakistan would kill and injure countless civilians, while risking massive nuclear retaliation by India. In this International Security article, Jaganath Sankaran argues Pakistan should reconsider the role of tactical nuclear weapons in its military strategy.

Chinese President Xi Jinping addresses China’s new concept of nuclear security with four “equal emphasis” at the third Nuclear Security Summit, and makes four commitments to strengthen nuclear security in the future. To convert President Xi’s political commitments into practical, sustainable reality, China should take further steps to install a complete, reliable, and effective security system to ensure that all its nuclear materials and nuclear facilities are effectively protected against the full spectrum of plausible terrorist and criminal threats. This paper suggests the following measures be taken to improve China’s existing nuclear security system, including updating and clarifying the requirements for a national level DBT; updating and enforcing existing regulations; further promoting nuclear security culture; balancing the costs of nuclear security, and further strengthening international cooperation on nuclear security.

Through structured interviews and a literature review, we assess which approaches to protection against insider thefts in the casino and pharmaceutical industries could be usefully applied to strengthen protections against insider theft in the nuclear industry, where insider thefts could have very high consequences.

This article examines and evaluates security measures at Chinese civilian nuclear power plants and suggests ways to improve them. It also reviews current export control policies and systems, identifies likely challenges to the expanding nuclear sector, and proposes possible solutions.

Matthew Fuhrmann's article "Spreading Temptation: Proliferation and Peaceful Nuclear Cooperation Agreements," was published by in the Summer 2009 issue of International Security. In his article, Dr. Fuhrmann argues "Peaceful nuclear cooperation—the transfer of nuclear technology, materials, or know-how from one state to another for peaceful purposes—leads to the spread of nuclear weapons. With a renaissance in nuclear power on the horizon, major suppliers, including the United States, should reconsider their willingness to assist other countries in developing peaceful nuclear programs."

Why do states provide sensitive nuclear assistance to nonnuclear weapon states, contributing to the international spread of nuclear weapons? Using a new dataset on sensitive nuclear transfers, this paper analyzes the determinants of sensitive nuclear assistance. Dr. Kroenig first describes a simple logic of the differential effects of nuclear proliferation, which is used to generate hypotheses about the conditions under which states provide sensitive nuclear assistance. He then shows that the strategic characteristics of the potential nuclear suppliers are the most important determinants of sensitive nuclear assistance. Explanations that emphasize the importance of economic motivations do not find support in the data. This paper presents a new approach to the study of the spread of nuclear weapons, focusing on the supply side of nuclear proliferation.

Hui Zhang re-examines the North Korean explosion on October 9, 2006. His research suggests that the test was likely not a failure if Pyongyang had planned for a yield of 4 kt, as it told Beijing prior to the event.
