contents Costly pre-play messages can deter unnecessary wars - but the same messages can also entrench stalemates once violence begins. We develop an overlapping-generations model of a security dilemma with persistent group types (normal vs bad), one-sided private signaling by the current old to the current young, and noisy private memory of the last encounter. We characterize a stationary equilibrium in which, for an intermediate band of signal costs, normal old agents mix on sending a costly reassurance only after an alarming private history; the signal is kept marginally persuasive by endogenous receiver cutoffs and strategic mimicking by bad types. Signaling strictly reduces the hazard of conflict onset; conditional on onset, duration is unchanged in the private model but increases once a small probability of publicity (leaks) creates a public record of failed reconciliation. With publicity, play generically absorbs in a peace trap or a conflict trap. We discuss welfare and policy: when to prefer back-channels versus public pledges.
