内容摘要：We study adversarial information design in a regime-change context. A continuum of agents simultaneously choose whether to attack the current regime. The attack succeeds if and only if the mass of attackers outweighs the regime's strength. A designer manipulates information about the regime's strength to maintain the status quo. Our optimal information structure exhibits local obfuscation: some agents receive a signal matching the regime's true strength, and others receive an elevated signal professing slightly higher strength. This policy is the unique limit of finite-signal problems. Public signals are strictly suboptimal, and in some cases where public signals become futile, local obfuscation guarantees the collapse of agents' coordination.
