Unblocking inertia: US-Russian nuclear arms control and missile defenses

The United States and Russia, in the aftermath of Russia’s annexation of Crimea and destabilization of Ukraine, seem to have ditched entirely the “reset” in their political relations. Despite this odor of Cold War redux, there remain the opportunities and necessities for renewed attention to strategic nuclear arms control as between the two governments. US and NATO missile defenses as planned for European deployment figure into this equation, although in somewhat unpredictable ways, given technological uncertainties in existing and foreseeable defenses, as well as the possibility of improved delivery systems for offensive conventional or nuclear weapons.

Nuclear Weapons and the Vietnam War

This article analyzes why US leaders did not use nuclear weapons during the Vietnam War. To date, there has been no systematic study of US decision-making on nuclear weapons during this war. This article offers an initial analysis, focusing on the Johnson and Nixon administrations. Although US leaders did not come close to using nuclear weapons in the conflict, nuclear options received more attention than has previously been appreciated. Johnson's advisers raised the issue of nuclear weapons and threats on several occasions, and Henry Kissinger, Nixon's national security adviser, looked into nuclear options to bring the war to an end. Ultimately, however, both administrations privately rejected such options. The conventional explanation for the non-use of nuclear weapons during the Cold War – deterrence – is insufficient to explain the Vietnam case. This article analyzes the role of military, political and normative considerations in restraining US use of nuclear weapons in the Vietnam War. It argues that while military and political considerations, including escalation concerns, are part of the explanation, a taboo against the use of nuclear weapons played a critical role.     

THE SECURITY IMPLICATIONS OF CHINA'S NUCLEAR ENERGY EXPANSION

Nuclear energy is an integral part of China's energy strategy and will increasingly contribute to China's total energy supply. China has more than twenty civilian facilities, including power reactors, mines, and enrichment plants, to support its nuclear power program. As China operates more nuclear plants, more nuclear materials will be produced and stockpiled, and more nuclear facilities will be spread around the country. To ensure that this expanded network of nuclear facilities does not increase the risk that nuclear materials will be diverted or become the target of attack, China will need to develop more reliable domestic nuclear security strategies. China is also poised to become a major exporter of nuclear energy technology. China has committed to keeping nuclear technologies out of the hands of dangerous states and/or sub-state organizations, but in order to fulfill its nonproliferation obligations as well as its treaty-based commitment to share nuclear technologies, China will need to strengthen nuclear export controls and practices. This report 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.     

NUCLEAR ISLANDS

Current International Atomic Energy Agency safeguards do not provide adequate protection against the diversion to military use of materials or technology from certain types of sensitive nuclear fuel cycle facilities. In view of highly enriched uranium's relatively greater ease of use as a nuclear explosive material than plutonium and the significant diseconomies of commercial spent fuel reprocessing, this article focuses on the need for improved international controls over uranium enrichment facilities as the proximate justification for creation of an International Nuclear Fuel Cycle Association (INFCA). In principle, the proposal is equally applicable to alleviating the proliferation concerns provoked by nuclear fuel reprocessing plants and other sensitive nuclear fuel cycle facilities. The INFCA would provide significantly increased nonproliferation assurance to its member states and the wider international community by holding long-term leasehold contracts to operate secure restricted zones containing such sensitive nuclear facilities.
