Selling international law enforcement: Elite justifications and public values

Abstract

International law enforcement is an understudied but indispensable factor for maintaining the international order. We study the effectiveness of elite justifications in building coalitions supporting the enforcement of violations of the law against territorial seizures. Using survey experiments fielded in the USA and Australia, we find that the effectiveness of two common justifications for enforcement—the illegality of a country’s actions, and the consequences of those actions for international order—increase support for enforcement and do so independently of two key public values: ideology and interpersonal norm enforcement. These results imply elites can build a broad coalition of support by using multiple justifications. Our results, however, highlight the tepidness of public support, suggesting limits to elite rhetoric. This study contributes to the scholarship on international law by showing how the public, typically considered a mechanism for generating compliance within states, can impede or facilitate third-party enforcement of the law between states.
