Retrenchment as a Screening Mechanism: Power Shifts, Strategic Withdrawal, and Credible Signals

Both advocates and opponents of retrenchment have treated it as an undesirable, last-ditch strategy for states that have already experienced severe decline. This article presents a formal model that identifies an unrecognized benefit of retrenchment: It can provide declining states with valuable information about rising states' future intentions. By removing constraints over the behavior of rising states in a particular region, a declining state can induce hostile risers to attempt revision of the regional order. This, in turn, makes a riser's cooperative behavior more credible as a signal of benign intentions, allowing the decliner to oppose hostile types while accommodating benign ones. In contrast to the existing focus on retrenchment as a desperate strategy taken from a position of weakness, this article suggests that the informational benefits of retrenchment are greatest when it is undertaken early, from a position of strength.
