Abstract:
Chinese views of nuclear escalation are key to assessing the potential for nuclear escalation in a crisis or armed conflict between the United States and China, but they have not been examined systematically. A review of original Chinese-language sources and interviews with members of China's strategic community suggest that China is skeptical that nuclear escalation could be controlled once nuclear weapons are used and, thus, leaders would be restrained from pursuing even limited use. These views are reflected in China's nuclear operational doctrine (which outlines plans for retaliatory strikes only and lacks any clear plans for limited nuclear use) and its force structure (which lacks tactical nuclear weapons). The long-standing decoupling of Chinese nuclear and conventional strategy, organizational biases within China's strategic community, and the availability of space, cyber, and conventional missile weapons as alternative sources of strategic leverage best explain Chinese views toward nuclear escalation. China's confidence that a U.S.-China conflict would not escalate to the use of nuclear weapons may hamper its ability to identify nuclear escalation risks in such a scenario. Meanwhile, U.S. scholars and policymakers emphasize the risk of inadvertent escalation in a conflict with China, but they are more confident than their Chinese counterparts that the use of nuclear weapons could remain limited. When combined, these contrasting views could create pressure for a U.S.-China conflict to escalate rapidly into an unlimited nuclear war.

Abstract:
When and how do domestic politics influence a state's nuclear choices? Recent scholarship on nuclear security develops many domestic-political explanations for different nuclear decisions. These explanations are partly the result of two welcome trends: first, scholars have expanded the nuclear timeline, examining state behavior before and after nuclear proliferation; and second, scholars have moved beyond blunt distinctions between democracies and autocracies to more fine-grained understandings of domestic constraints. But without linkages between them, new domestic-political findings could be dismissed as a laundry list of factors that do not explain significant variation in nuclear decisions. This review essay assesses recent research on domestic politics and nuclear security, and develops a framework that illuminates when and how domestic-political mechanisms are likely to affect nuclear choices. In contrast to most previous domestic arguments, many of the newer domestic-political mechanisms posited in the literature are in some way top-down; that is, they show leaders deliberately maintaining or loosening control over nuclear choices. Two dimensions govern the extent and nature of domestic-political influence on nuclear choices: the degree of threat uncertainty and the costs and benefits to leaders of expanding the circle of domestic actors involved in a nuclear decision. The framework developed in this review essay helps make sense of several cases explored in the recent nuclear security literature. It also has implications for understanding when and how domestic-political arguments might diverge from the predictions of security-based analyses.

3. Proliferation and the Logic of the Nuclear Market

Abstract:
The evolution of the nuclear market explains why there are only nine members of the nuclear club, not twenty-five or more, as some analysts predicted. In the absence of a supplier cartel that can regulate nuclear transfers, the more suppliers there are, the more intense their competition will be, as they vie for market share. This commercial rivalry makes it easier for nuclear technology to spread, because buyers can play suppliers off against each other. The ensuing transfers help countries either acquire nuclear weapons or become hedgers. The great powers (China, Russia, and the United States) seek to thwart proliferation by limiting transfers and putting safeguards on potentially dangerous nuclear technologies. Their success depends on two structural factors: the global distribution of power and the intensity of the security rivalry among them. Thwarters are most likely to stem proliferation when the system is unipolar and least likely when it is multipolar. In bipolarity, their prospects fall somewhere in between. In addition, the more intense the rivalry among the great powers in bipolarity and multipolarity, the less effective they will be at curbing proliferation. Given the potential for intense security rivalry among today's great powers, the shift from unipolarity to multipolarity does not portend well for checking proliferation.

4. Keeping the Bombs in the Basement: U.S. Nonproliferation Policy toward Israel, South Africa, and Pakistan

Abstract:
Many accounts suggest that the United States did little to prevent Israel, Pakistan, and South Africa from developing nuclear weapons. These accounts are flawed, however. The United States did attempt to stop all three countries from acquiring the bomb and, when those efforts failed, to halt additional proliferation measures such as further testing and weaponization.
