‘Subordinate monopolization and the origins of major power conflict’ (forthcoming at Security Studies)
An overlooked pathway through which rising powers may be drawn into conflict with major powers is competition over small states and territories. When a rising power seeks to monopolize a subordinate, preventing other major powers from pursuing their interests in its territory, this challenges the material interests of other major powers and violates norms of open subordinate governance. To address this violation, threats and force may be employed. Moreover, the monopolizer is perceived as having revisionist preferences for international order, meaning future interactions are more discordant, making conflict more likely. This argument is evaluated through quantitative examination of rising power disputes between 1816 and 2010 and comparative case study analysis of Russo-Japanese and Spanish-American Wars. Contestation of the norms of subordinate governance play an important role in shaping the probability of major power conflict, and provide insight into the behavior of the major powers in the contemporary international order.
How have understandings of fundamental norms of international society changed over time? How does this relate to the decline of interstate violence since 1945? Previous explanations have focused on regime type, domestic institutions, economic interdependence, relative power, and nuclear weapons, I argue that a crucial and underexplored part of the puzzle is the change in understanding of sovereignty over the same period. In this article, I propose a novel means of examining change in these norms between 1970 and 2014 by analyzing the content of UN Security Council resolutions. This analysis is then utilized in quantitative analysis of the level of violence dispute participants resorted to in all Militarized Interstate Disputes in the period. I find that as liberal understandings of fundamental norms have increased, that the average level of violence used has decreased. This points to a crucial missing component in the existing literature: that institutions can only constrain when political actors share the right norms.
Works in progress
Book project: ‘Open Hierarchies: Access and Order in World Politics’’
I examine how access to subordinate states shapes international order, arguing that stable orders depend not on the absence of hierarchy, but on norms that limit exclusive control over subordinate states. When states seek to establish exclusive access to subordinate states through political, military, or economic means, they challenge these norms, increasing the risk of major power conflict. Combining quantitative analysis with comparative historical case studies, I develop a new theory of hierarchy, strategic competition, and the governance of international order. I examine these dynamics through the strategies of major powers, subordinate states, and state-backed firms, showing how each shapes patterns of access and influence.
‘The location of rising power disputes: social position and regional expansion’
I argue that the social position of rising powers has an influential effect upon the location of disputes rising powers enter into. In short, those rising from within the ranks of the great powers tend to have extra-regional disputes, whilst those rising from below the great powers concentrate in their home region.
‘Second rank powers and international order’
How do second rank states impact the international order? What are their strategies? This project seeks to understand the place of states on the fringes of the major powers in international relations, and their impact on the international order. It seeks, therefore, to understand states that are rising and declining, as well as those that endure at a level just outside of the major powers.
‘War, victory, and state formation’ (with Luis L. Schenoni, UCL)
This project examines how victory in interstate wars impacts state capacity over the longer term from 1816 onwards.
‘The impact of UN peacekeeping norms on interstate conflict’
I utilize content analysis of UNSC and UNGA resolutions to understand the evolution of peacekeeping norms, and applies this to the success of peacekeeping missions.
