How robust is public support for extended nuclear deterrence in patron and client states? Recent studies have improved scholarly understanding of US public opinion about nuclear weapon use against non-nuclear adversaries. Yet, there is limited knowledge of public attitudes regarding retaliation for nuclear strikes against US allies. We develop a theoretical typology of nuclear crises and investigate this phenomenon with a novel survey experiment ( n = 6,623). Americans, Japanese, and South Korea

Abstract How does a patron state dampen a client state's domestic aspirations for developing nuclear weapons? What nonproliferation tools most effectively induce a client state's domestic preference for nuclear forbearance? This article assesses the relative effectiveness of three nonproliferation tools available to a nuclear patron: a declaration of extended deterrence, forward deployment of nuclear weapons, and a conditional threat of punishment. More specifically, using experimental data on t

Abstract Does the rise of nationalism lead to immigration policy change? By focusing on elite‐led nationalism, this study offers a novel perspective: When top political leaders rely on nationalism as their legitimation strategy, they are more disposed to adopt policies aimed at strict immigration control, such as the imposition of sanctions on illegal immigrants, due to their hands being tied. We perform a battery of empirical tests using a cross‐national, time‐series data for 33 countries for t

How can democratic governments convince their citizens to support a costly military alliance? We theorize about two rhetorical tools that foreign policy leaders have historically used to achieve this goal: instrumental cues emphasizing national interests and ideational cues highlighting shared values. We then assess the effects of these appeals in various forms and contexts by analyzing two original survey experiments fielded in the United States. Our analysis shows that alliance rhetoric – whet

ABSTRACT In the field of international relations, it has long been believed that nationalism generates adverse foreign policy preferences. This article revisits this long-standing assumption by investigating how stimulating nationalistic sentiments shapes mass foreign policy preferences in two contexts, namely when celebrating national achievements and greatness with a focus on the national Self and when invoking negative historical memories in relation to a salient Other. Using a survey experim

Abstract When Japan in 2019 removed South Korea from its whitelist of most trusted trading partners, South Koreans responded by organizing mass nationalist boycotts against Japanese goods. What affects South Korean citizens’ willingness to participate in this nationalist movement? In this article, we offer a systematic investigation of individuals’ motivations behind their boycott participation along the two dimensions of nationalist boycotts – boycotts as a collective choice and boycotts as an

We examine how a great power’s past behavior toward an informal security partner affects the broader credibility of its security commitments, focusing on the implications of America’s dramatic troop withdrawal from Afghanistan in 2021 as perceived by the U.S., South Korean, and Chinese publics. Against conventional wisdom, we show that knowledge about a great power’s decision to abandon an informal partner in one region of the globe can help increase confidence about its alliance commitments els

Abstract Does nationalism lead to interstate war? This book challenges the widely held assumption that nationalism causes war and systematically investigates how popular nationalism affects a country’s decision to launch military aggression. The book makes a novel and provocative claim that popular nationalism has not only a conflict-inducing effect but also a restraining one, and identifies the conditions under which popular nationalism triggers interstate violence. Specifically, the book asser

Despite growing research on nationalism and its impact in international relations, little work has been done on how the rise of nationalism in host countries influences foreign direct investment (FDI), a key driver for promoting economic growth. We hypothesize that multinational corporations are less likely to enter host countries with high nationalism, due to the multiple risks that high nationalism entails, such as nationalist boycotts and changes in policy initiatives, and that this dampening

Abstract This chapter begins by introducing the theoretical and empirical puzzle of the book: does popular nationalism cause interstate war? To answer this question, the chapter first defines what popular nationalism is and discusses its several distinctive characteristics. In doing so, the chapter clarifies how popular nationalism differs from other related concepts, such as populism, ethnic nationalism, and civic nationalism. It then discusses from whom popular nationalism emerges and defines

In the era of the Fourth Industrial Revolution, classical education has become more important, and the direction of classical education in universities is changing. Therefore, I designed a college classical course to develop the necessary capabilities among students in this rapidly changing era. Among the Chinese classics, <i>Zhuangzi</i> was selected as a recommended book by many universities. The fables contained in <i>Zhuangzi</i> lower the threshold for the study of t

Abstract This chapter proposes a new theory of popular nationalism and war by investigating how popular nationalism factors into political leaders’ strategic decision to launch military aggression. It elucidates how popular nationalism creates two contrasting incentives with regard to the initiation of militarized conflict, and how those incentives, coupled with the two moderating variables—political elites’ perceived chance of victory in conflict and their domestic political vulnerability—ultim

Abstract This chapter investigates how domestic political vulnerability, or the lack thereof, leads to different strategic decisions of leaders confronting popular nationalism. It examines how American popular nationalism contributed to the outbreak of the War of 1812 between the United States and Great Britain. While American popular nationalism exerted pressure on the country’s leaders to declare a war against mighty Great Britain over several maritime issues, it resulted in divergent outcomes

Abstract This chapter investigates how Chinese popular nationalism has influenced the country’s decision of using force or maintaining the status quo in the Senkaku/Diaoyu/Diaoyutai Islands dispute between China/Taiwan and Japan in the East China Sea. The chapter illustrates how China has mainly exercised restraint and maintained the status quo in this dispute, despite strong popular nationalism. Although China has been rising rapidly, its complete victory in conflict has been a distant possibil
