Iran's Coercive Leverage: The Desalination Plant Gambit

One of the most strategically significant dynamics in the current Iran-U.S. conflict is Iran’s asymmetric advantage: economic coercive leverage. While the U.S. military still possesses superior firepower, Iran holds a card that matters equally or more in the calculus of modern geopolitics: control over the Strait of Hormuz and the ability to strike the critical infrastructure that sustains the Gulf states.

Hovik and Asbed explore this inversion. Unlike Iran, which relies on desalination for less than 10% of its freshwater needs, the Gulf states are almost entirely dependent on desalination infrastructure. Kuwait is 90% reliant; Saudi Arabia and Oman similarly depend on these plants for survival. When the U.S. struck desalination facilities in Iran’s Hormuzgan province, Iran retaliated by targeting desalination and power plants in Kuwait, creating an existential threat for regional allies of the United States. This forced Kuwait, Saudi Arabia, and others to call Trump directly, demanding de-escalation.

The irony is sharp: Washington escalated against civilian infrastructure without accounting for the fact that its own regional allies are far more vulnerable to retaliation. Iran, by contrast, holds the power to block the Strait of Hormuz, through which roughly one-third of global seaborne oil passes. A sustained blockade would tank global markets instantaneously. This is why Mearsheimer argues Iran now holds stronger negotiating leverage than it did on June 17, when the failed U.S.-Iran memorandum of understanding was signed. Any future negotiation will tilt in Iran’s favor, provided Tehran maintains the credible threat of economic disruption.
