Reception to follow from 5:00pm - 6:30pm in the lobby in front of the William J. Perry Conference Room

About the event: We use survey experiments to explore a variety of different contexts and how they affect the choices a decision maker might have to make about using nuclear weapons. One set of surveys explores the relationship between expected casualties and the willingness to use nuclear weapons. The result is clearly increasing support for nuclear use as expected casualties in a difficult conventional war increase. We also explore how the alternatives given to a decision maker influence choice. More specifically, we show that when the option not to launch nuclear weapons is presented along with three options to use those weapons, more people select not to launch. Overall, we also find clear evidence of consistent differences between democrats and republicans as well as a strong relationship between decision makers’ punitive tendencies and their support for using nuclear weapons. Implications for risk management and policy will be discussed.

About the event: Vladimir Putin’s full-scale invasion of Ukraine in 2022 has cast a spotlight on Russia’s burgeoning partnership with Iran. Moscow looked to Tehran for drones and ammunition to fuel its so-called ‘special military operation’, and Iran’s support for Russia’s war reflected a decade-long strengthening of Russo-Iranian ties, beginning with the 2011 outbreak of the Syrian Civil War.

Despite a relationship historically marred by mistrust and unmet expectations, the two regimes have worked together to promote their common interests in Syria, where battlefield coordination soon developed into much deeper political alignment. Nicole Grajewski uncovers the drivers of ever-closer cooperation between the Kremlin and the Islamic Republic. Detailing the internal structures, shared anxieties and broader ambitions underpinning this alignment, she explores the genesis of Russia and Iran’s mutual antagonism towards the Western-led global order; the impact of deep-seated leadership concerns over regime security and domestic protests; and the future trajectory of the partnership within the larger world order.

About the speaker: Nicole Grajewski is a fellow in the Nuclear Policy Program at the Carnegie Endowment for International Peace and an Associate with the Project on Managing the Atom at the Harvard Kennedy School's Belfer Center. She holds a PhD in International Relations from the University of Oxford and is the author of Russia and Iran: Partners in Defiance from Syria to Ukraine.

About the event: When states go to war, they must devise a strategy that anticipates how their use of military force will achieve national objectives. But that choice is heavily constrained. This book project shows how wartime strategy is a function of both dispositional and situational factors - that is, the military’s abiding organizational preferences, and the government’s contingency-specific decisions, respectively. This presentation focuses on one of the book’s key theoretical contributions: how a military’s structure and processes reveal its unwritten warfighting preferences. In the Indian case, official doctrine pronouncements suggest a military that is postured to fight state of the art maneuver warfare. But, in reality, its entrenched preferences have not changed in over half a century, and heavily favor attritional combat. Doctrine, of course, is not destiny - states like India can and have fought differently under certain extraordinary conditions. But absent those rare conditions, the Indian Army’s attritional preferences dominate the state’s strategic options, which has implications for conventional deterrence and strategic stability.

About the event: Why do some leaders reposition themselves on salient foreign policy issues in ways that may contradict their earlier behavior or rhetoric? I argue that expectations of how leaders ought to behave are tied to their reputations; however, leaders are also both strategic actors and reputationally mindful. In other words, leaders have strategic incentives to either maintain or moderate their reputations on salient foreign policy issues – a phenomenon I term reputation management. Using controlled case comparisons of eight cases of foreign policy position-taking across India, Israel, South Korea and the United States, I argue that two variables -- the salience of a moderation imperative, and the degree of electoral constraint circumscribing leader behavior -- determine the opportunity costs for leaders to either maintain or moderate their reputations, which outwardly manifests as behavioral consistency or inconsistency respectively.

About the speaker: Fahd Humayun is a Stanton Nuclear Security Fellow at Stanford University’s Center for International Security and Cooperation (CISAC). He completed his PhD in Political Science from Yale University in 2022 before joining Tufts University as an Assistant Professor of Political Science. His research looks at the domestic sources of interstate conflict and crisis behavior, expanding on existing theories of democratic accountability and political representation as they pertain to domestic decision-making and crisis signaling. His book project, “Leaders, Reputation & War” uses case studies of foreign policy position-taking India, Israel, South Korea and the United States to explain why domestic politics compels some leaders to commit to unanticipated national security pathways. He also holds an MPhil from the University of Cambridge and a BSc in International History from the London School of Economics.

About the event: In nearly every country with sizable armed forces, debates persist about the relative effectiveness of military recruitment systems. Conventional wisdom asserts that volunteer armies fight more effectively in battle than conscript armies due to higher levels of training and motivation. I argue instead that conscript forces outperform their volunteer counterparts for several reasons. First, higher domestic political costs of sending draftees into combat incentivize leaders to vet military operations more carefully. Second, the leaders restrict conflicts to those that involve broadly recognized national interests, for which individual conscripts are highly motivated to bear real costs. Third, the average demographic makeup of conscript armies is superior to that of volunteer armies, which translates into advantages in battlefield skill acquisition. Democratic regime type and longer enlistment terms further bolster the battlefield effectiveness of conscript armies. I provide support for these propositions by analyzing cross-national battle-level data as well as American battlefield performance during the Vietnam War. My findings contribute to debates about military recruitment policy and civil–military relations.

About the event: Scholars have long debated why some conflicts spiral into prolonged cycles of hostility, while others fizzle out. Conventional wisdom suggests that states, when challenged, can demonstrate their resolve by retaliating militarily, thereby deterring future challenges. I argue that the desire for revenge, rather than deterrence concerns, shapes when individuals prefer military retaliation and why such actions provoke cyclical conflicts. Public support for military retaliation is primarily driven by a human desire to balance the suffering inflicted upon one's own ingroup, often without regard for the consequences. Consequently, instead of achieving deterrence, imposing costs on an adversary through military retaliation tends to provoke reciprocal retaliation. I test my theory using a preregistered survey experiment in which China attempts to deter U.S. intervention in a hypothetical Taiwan Strait crisis through retaliation. The results align with the logic of revenge. Rather than deterring the U.S., China's retaliation, which imposes greater suffering on the U.S., increases public support for further escalation, even in scenarios of secret U.S. retaliation with no deterrent benefit. This study contributes to the deterrence versus spiral model debate in two ways. First, it challenges the deterrence model, particularly theories of reputation for resolve. Second, it complements the spiral model by providing an alternative psychological microfoundation for the endogenous emergence of conflict spirals.

About the event: Modern survey experiments indicate that in the event of a limited nuclear strike, the public in the targeted country, including a great democracy, would demand a decisive response. The implications for crisis stability are dire. Just at the moment when democratic decision makers would struggle to formulate a proportional response, they would also have to contend with an enraged populace shouting for vengeance. Public opinion as recently characterized is anathema to sound crisis management. The same mass sentiment that bolstered democratic resolve in the triumphal years after the Cold War now abandons presidents in the age of nuclear multipolarity to foredoomed strategies that overplay their hand. This, however, is not the whole story. Public opinion in real life also prevents leaders from throwing it all away or allowing crises to slip out of control. The Missiles of October in 1962 threatened international peace under different geopolitical circumstances, but the role of public opinion then has lessons for today. What might be called the Robert McNamara-Brent Scowcroft school still reigns. Rather than preclude crisis management, public opinion on net enables it: amplifying popular demand for peace and motivating extraordinary leader performance to preserve it.

About the speaker: Dr. Damon Coletta served as the endowed Scowcroft Professor of Political Science (2020-2021) at the United States Air Force Academy and director of the department’s Eisenhower Center for Space and Defense Studies (2022-2023).  Damon edits the peer-reviewed e-journal, Space & Defense (2012-2024) and serves as social sciences liaison to USAFA’s nationally recognized Nuclear Weapons & Strategy minor program.  He completed a book on science & technology policy and international security, Courting Science: Securing the Foundation for a Second American Century (Stanford, 2016), and coedited NATO’s Return to Europe (Georgetown, 2017).

About the event: The Responsibility to Protect (R2P) has been invoked over one hundred times since its formal endorsement by the UN General Assembly in 2005. Although R2P was designed to protect populations around the world from mass atrocity, it is selectively applied to societies outside of the North. Cases of inaction are also observed over atrocities in the South that would otherwise qualify for intervention by UN standards. Why does the international community intervene in some cases and not others? I argue that R2P betrays a racialized bias whereby the legal principle of sovereignty is transformed into a conditional privilege withheld from most non-European countries all else equal. Debates over a peoples’ capacity for self-rule are historically framed or even justified by racism. Since R2P restores a similar debate wherein state sovereignty becomes contingent, it can affirm prevailing beliefs about race and capacity for self-governance as a means to political ends. I examine R2P cross-nationally by matching countries on characteristics that likely drive intervention. Using UN resolutions and original data on mass atrocity events, I measure the relationship between country racial majority and the decision to intervene. The results suggest that R2P is disproportionately invoked over societies racialized as non-white. To address variation in R2P invocation over countries in the South, I examine a set of cases qualitatively and show that inaction by the international community is racial as it is strategic. A theory of race deepens understanding of the contradictory values that cohere to shape international law and intervention.

Join Stanford's Shorenstein APARC China Program as we welcome Professor Rory Truex from Princeton University to present his recent survey findings on the evolving perspectives of U.S. foreign policy professionals toward China. Based on a survey of nearly 500 professionals and over 50 in-depth interviews, the research reveals a spectrum of policy opinions, alongside a concerning trend of "groupthink" that often shifts discussions toward more hawkish stances. Professor Truex will explore how career and reputational pressures influence these dynamics, shedding light on the shaping of China-related discourse within Washington’s foreign policy circles.
