How do policymakers infer the long-term political intentions of their states' adversaries? A new approach to answering this question, the “selective attention thesis,” posits that individual perceptual biases and organizational interests and practices influence which types of indicators a state's political leaders and its intelligence community regard as credible signals of an adversary's intentions. Policymakers often base their interpretations on their own theories, expectations, and needs, sometimes ignoring costly signals and paying more attention to information that, though less costly, is more vivid (i.e., personalized and emotionally involving). In contrast, intelligence organizations typically prioritize the collection and analysis of data on the adversary's military inventory. Over time, these organizations develop substantial knowledge on these material indicators that they then use to make predictions about an adversary's intentions. An examination of three cases based on 30,000 archival documents and intelligence reports shows strong support for the selective attention thesis and mixed support for two other approaches in international relations theory aimed at understanding how observers are likely to infer adversaries' political intentions: the behavior thesis and the capabilities thesis. The three cases are assessments by President Jimmy Carter and officials in his administration of Soviet intentions during the collapse of détente; assessments by President Ronald Reagan and administration officials of Soviet intentions during the end of the Cold War; and British assessments of Nazi Germany before World War II.
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.
