Iran’s emerging doctrine for confronting the United States, Israel and the Gulf monarchies is not built around winning battles. It is built around making war too costly to fight. Rather than trying to defeat the US Navy or Israeli Air Force head‑on, Tehran is developing what might be called a strategy of thirst and hunger: a form of “hydraulic warfare” that targets water, energy and food systems at their weakest points.
At the heart of this approach is a hard geographic reality. The Arabian Peninsula and Israel are some of the most water‑scarce regions on earth. They survive not because the climate allows it, but because industrial technology forces it: huge, energy‑intensive desalination plants provide a large share of drinking water for Gulf states and for Israel. Those plants are coastal, fixed, and heavily concentrated. If you can disable a few dozen facilities, you don’t just hurt an adversary’s economy – you threaten the basic habitability of entire countries.
Over the past two decades, Gulf governments have poured billions into desalination to secure their survival. Kuwait gets the vast majority of its drinking water from eight plants. Qatar has built over a hundred, supplying nearly half its needs. The UAE operates dozens, while Saudi Arabia runs “super plants” that provide more than half the country’s potable water. Israel, similarly, relies on a small number of large facilities that together meet most domestic demand.
This success story carries an embedded vulnerability. In a region where summer temperatures routinely exceed 45 degrees Celsius, even a short disruption in water supplies can become a humanitarian emergency. Within days, not weeks, populations in the millions would face choices between rationing, evacuation and unrest. Health systems would be overwhelmed, agriculture would collapse, and industrial activity would grind to a halt.
Iran’s planners have clearly understood this. Instead of treating desalination plants as just another critical infrastructure category, they have elevated them into strategic levers. Hit a desalination complex or the power grid that feeds it, and you create a crisis that is politically explosive but still technically “limited” – you are not bombing cities, but the effect on those cities is immediate and profound. That distinction matters in the court of international opinion, and in Tehran’s calculus, it creates space for coercion short of total war.
The second pillar of Iran’s strategy is the Strait of Hormuz, the 21‑mile‑wide passage through which about one‑fifth of global oil consumption and a similar share of LNG trade flows. For decades, Hormuz has been recognized as a strategic chokepoint. Iran has spent years turning it into something more: a kind of economic minefield in which any shooting incident risks detonating worldwide price spikes and shipping chaos.
Iran cannot hope to “control” the Strait in the classic naval sense. But it doesn’t need to. By deploying fast boats, mini‑submarines, naval mines and long‑range drones along the approaches, and by integrating their targeting with external intelligence and surveillance, Tehran can make transit through Hormuz look uninsurable during a crisis. Energy companies, shipping lines and insurers are finely tuned to risk. A few well‑placed attacks or even credible threats could be enough to divert tankers around Africa, stretch delivery times and send oil prices doubling in days.
Here, again, Iran’s objective is not to defeat an enemy fleet. It is to force everyone else – from Washington to Beijing – to ask whether confronting Tehran militarily is worth the shock to energy markets, inflation and domestic politics.
Iran’s “hydraulic warfare” concept relies on combining different tools to create overlapping crises. One layer is kinetic: missiles and drones aimed not at city centers but at desalination facilities, pumping stations and power plants that feed them. Iran has already shown that it can reach targets across the Gulf with ballistic missiles and cruise systems.
Another layer is cyber. Water and power infrastructure is heavily automated. Disrupting control systems, scrambling sensor data or triggering shutdown protocols can disable critical assets without leaving a smoking crater. Iranian‑linked actors have already been accused of probing or attacking water and power networks, particularly in Israel. Such operations serve both as testing grounds and as a warning: these systems are reachable.
The third layer is economic. By threatening Hormuz, Iran indirectly hits not just its immediate adversaries but the broader global food and energy system. The Gulf is a major transit route for grain, cooking oils, frozen meat and especially fertilizers like ammonia and sulfur used worldwide. If shipping through Hormuz and the Suez corridor is deemed too dangerous, vessels must sail thousands of extra kilometers. Freight costs and insurance premiums soar, and the ripple effects show up in supermarket prices from Cairo to Kolkata to Berlin.
