US Backdowns Undermine Sanctions: Past Empty Threats Reduce Acquiescence

Why Reputation Matters for Sanctions?

Timothy M. Peterson investigates how the credibility of U.S. sanction threats shapes whether targeted states give in. Scholarship often assumes that empty threats damage a sender's reputation, but little work tests how targets actually respond to a sender's prior behavior. Peterson argues that targets look at how the United States has treated previously resistant states: if the U.S. recently backed down, a current target infers that threats are likely empty and is less likely to acquiesce; if the U.S. recently imposed sanctions on a resistant state, the current target expects enforcement and is more likely to comply.

How the Study Tests That

• The analysis uses a statistical examination of U.S. sanction threats from 1971–2000, treating target acquiescence to threats as the outcome of interest.
• Key independent variables capture whether the United States recently backed down from threats or recently imposed sanctions on other resistant targets, letting the study assess how prior sender behavior influences expectations about enforcement.
• The empirical strategy connects observable patterns in U.S. behavior to target responses rather than assuming reputation costs a priori.

Key Findings

• Strong evidence that when the United States recently backed down from a sanction threat, subsequent targets are significantly less likely to acquiesce—consistent with reputational damage from apparent empty threats.
• Weaker but suggestive evidence that recent U.S. imposition of sanctions against a resistant target increases the likelihood that a new target will acquiesce.

Implications for Coercive Diplomacy

These results show that reputational dynamics in sanctions operate through observable patterns of enforcement: targets update expectations based on how senders treated other resistant states. For policymakers, the study highlights that decisions to impose or forego sanctions have spillover effects on future credibility. For scholars, the paper reframes reputation as a forward-looking inference by targets grounded in prior sender actions rather than an abstract cost assumed in models of coercive diplomacy.
