The Politics of Punishment: Why Dictators Join the International Criminal Court

Abstract

Abstract Scholars commonly argue that international law and organizations promote democracy by helping dictators to credibly commit to accountability, individual rights, and transparency. Yet dictators routinely join treaties and international organizations without transitioning to democracy. International law and organizations can generate asymmetric costs for domestic actors because international rules often apply to both governments and non-state actors, yet dictators can limit how these rules are upheld at the domestic and international level. We argue that dictators are most likely to join such treaties and international organizations when they face strong domestic political competition. We illustrate our argument using the International Criminal Court (ICC), which has extensive powers to prosecute individuals for international crimes, including crimes against humanity, genocide, and war crimes. We show that ICC investigations and prosecutions have become a tool for incumbent dictators to target their domestic opponents. We examine the implications of our theory for multiple outcome variables, including the decision to join the ICC, violence, and the survival of dictators in power. Our evidence suggests that dictators are most likely to join the ICC when they face strong political opponents and are subsequently less likely to commit violence and more likely to survive in office.
