Means Without Ends: Assessing American Statecraft During Operation Earnest Will

Operation Earnest Will, the U.S. Navy’s effort to escort reflagged Kuwaiti tankers through the Persian Gulf between 1987 and 1989, was the largest American naval surface operation since World War II. The operation took place against the backdrop of the Iran-Iraq War, a bloody eight-year conflict that threatened the stability of the Persian Gulf, the flow of global energy resources, and the regional influence of the United States. The operation was driven by a combination of strategic imperatives: protecting vital oil shipping lanes as defined by the Carter Doctrine, denying the Soviet Union an opportunity to expand its influence in the Gulf, and restoring American credibility among Gulf Arab allies following the Iran-Contra scandal.

The Reagan administration practiced sound statecraft in the lead-up to the operation, exhausting diplomatic and economic tools before committing military assets. However, once Earnest Will began, the administration escalated militarily without articulating a clear political endgame. Iran, isolated diplomatically, economically strangled by sanctions and the arms embargo, and facing a superior U.S. naval force, nonetheless continued attacking international shipping because measured violence in the Gulf was effectively its last remaining strategic option. The U.S. climbed an escalation ladder without offering Iran a viable offramp, and bilateral confrontation only ended after Iran faced substantial battlefield losses against Iraq.
