Understanding US Policy Shifts in Iran Through Game Theory Analysis

“Mission accomplished.” This phrase has cast a long shadow over U.S. foreign policy since 2003, when George W. Bush triumphantly declared victory on the aircraft carrier Abraham Lincoln—only for the conflict to endure for another eight years. It has come to symbolize the disconnection between military objectives and reported achievements.

The conflict surrounding the Strait of Hormuz is escalating as we enter the second month of tension. Insights from game theory, which studies strategic decision-making, can help illuminate these complex dynamics.

In a traditional military confrontation, the combined might of the United States and Israel stands unmatched. Their advanced weaponry and precision strike capabilities significantly damage Iran’s military infrastructure, suggesting a traditional victory for the alliance.

However, this situation diverges from conventional warfare. It has transformed into a war of attrition, where multiple “players” engage in a costly stalemate, each hoping that the opposing side will eventually falter. Game theory posits that in such scenarios, victory is less about military might and more about which side can endure losses longer. Time is particularly on Iran’s side in this equation.

While Iran incurs significant costs, they remain manageable for the regime. Notably, the Iranian government exhibits an impressive ability to regenerate its command structures—removing one layer of leadership merely allows another to take its place. Moreover, their stockpiles of missiles and cost-effective drones keep replenishing faster than they are used.

In contrast, the United States faces a far steeper financial burden. Maintaining naval dominance in the straits demands continuous, costly deployments. Each drone interception, carrier rotation, and diplomatic effort to sustain a wavering coalition adds to the mounting expenses. In a war of attrition, the asymmetry of costs becomes more critical than raw firepower, and this factor unfavorably affects American interests.

A Blurry Objective

This structural reality explains the Trump administration’s ambiguous definition of victory—a point that has puzzled many. This lack of clarity serves a strategic purpose. Game theory suggests that when battlefield conditions are unfavorable, it is beneficial to obscure objectives.

To devise an effective strategy and foresee potential outcomes, one must first comprehend each player’s goals. Yet, the parameters seem to continuously shift.

This conflict did not initially revolve around the straits. The original aims included regime change, dismantling Iran’s nuclear capabilities, and neutralizing the Islamic Revolutionary Guards Corps. The narrowing of these goals to the more limited objective of controlling the straits signifies a loss of momentum for the campaign.

Interestingly, game theory identifies a dual advantage in such ambiguity. Unconsolidated objectives limit interaction; players who remain vague on their goals have the flexibility to proclaim victory and exit the situation on their terms.

Unclear objectives provide an adaptability that concrete commitments do not. This allows a player with undefined goals to escape accountability for failing to achieve them, and they may even be perceived as successful if they possess the necessary diplomatic skill. President Donald Trump has utilized this strategy throughout his two terms in office.

Moreover, time constraints play a crucial role. Research into the political economy of conflict indicates that leaders facing imminent electoral decisions experience pressure to conclude wars of attrition before voters cast their ballots. With midterm elections approaching, President Trump’s options for securing a withdrawal are rapidly diminishing.
