What public pressures do leaders face in international disputes? Leaders often denounce foreign actions as provocations, triggering public anger and demands for restitution. Rather than generating a reflexive rally around the flag, we argue that leaders who invoke foreign provocations-whether hypothetical, remembered, exaggerated, or real-face heightened public disapproval if they fail to take tough action in the present. Across two survey experiments and a quasi-experiment involving US naval patrols in the South China Sea, we find that incidents construed as provocative increase public pressure on the Chinese government to respond or incur public disapproval. We discuss possible explanations, how government elites seek to mitigate public disapproval, and how such events can change the logic of coercion and deterrence.
