The threat of escalating conflict in the Middle East took on a new dimension this week as former U.S. President Donald Trump warned of potential strikes against Iran’s infrastructure, including its desalination plants. The statement, made on his Truth Social platform, raises serious concerns about the potential for widespread humanitarian consequences and the targeting of civilian infrastructure in a region already grappling with severe water scarcity. While the immediate intent appears to be applying pressure on Iran regarding the Strait of Hormuz, the implications of attacking desalination facilities extend far beyond Tehran, threatening the water supply of millions across the Gulf.
Trump’s post indicated that if a deal to reopen the vital shipping lane isn’t reached “shortly,” the U.S. Might “blow up and completely obliterate” Iranian energy infrastructure, with desalination plants included as a possible target. This rhetoric, coupled with recent strikes and counter-strikes between Iran, Israel, and the United States, has heightened anxieties about a wider regional war. Experts warn that while a direct attack on Iran’s desalination capacity might be limited in immediate impact – Iran relies on desalination for a relatively small portion of its water needs – the potential for retaliation against Gulf Arab states, which are heavily dependent on desalinated water, is a significant and destabilizing risk.
The Vulnerability of “Saltwater Kingdoms”
The Persian Gulf region is one of the most water-stressed areas in the world. Decades of rapid population growth, industrialization, and the impacts of climate change have depleted natural freshwater sources, making desalination a critical lifeline for countries like Kuwait, Saudi Arabia, and the United Arab Emirates. According to the International Desalination Association, Kuwait obtains approximately 90% of its drinking water through desalination, while Oman relies on it for roughly 86% and Saudi Arabia for around 70%. These facilities, which remove salt from seawater using technologies like reverse osmosis, are essential for sustaining urban centers, agriculture, and industry.
“Everyone thinks of Saudi Arabia and their neighbours as petrostates. But I call them saltwater kingdoms,” said Michael Christopher Low, director of the Middle East Center at the University of Utah. “They’re human-made fossil-fuelled water superpowers. It’s both a monumental achievement of the 20th century and a certain kind of vulnerability.”
A Potential War Crime and Asymmetrical Response
The deliberate targeting of civilian infrastructure, particularly facilities essential for the survival of the population, is prohibited under international humanitarian law, including the Geneva Conventions. Niku Jafarnia, a researcher at Human Rights Watch, stated that “Desalination facilities are oftentimes necessary for the survival of the civilian population and intentional destruction of those types of facilities is a war crime.” The vulnerability of these plants is compounded by their often limited protection against missile or drone strikes, as noted by Ed Cullinane, Mideast editor at Global Water Intelligence: “None of these assets are any more protected than any of the municipal areas that are currently being hit by ballistic missiles or drones.”
Analysts suggest that Iran, while possessing limited capacity for a direct, large-scale military response against the United States, could leverage its missile arsenal to target desalination plants in Gulf Arab states as a means of exerting pressure and escalating the conflict. David Michel, senior fellow for water security at the Center for Strategic and International Studies, described this as an “asymmetrical tactic,” allowing Iran to “impose costs on the Gulf countries to push them to intervene or call for a cessation of hostilities.”
Iran’s Own Water Crisis and Regional Implications
While the Gulf states are more reliant on desalination, Iran itself is facing a severe water crisis. A five-year drought has left reservoirs supplying Tehran critically low, with some reports indicating levels below 10% capacity, as confirmed by satellite imagery analyzed by The Associated Press. Israeli airstrikes on oil depots near Tehran on March 7 also raised concerns about potential contamination of the city’s water supply due to acid rain and smoke. This existing water stress makes any disruption to Iran’s limited desalination capacity, or its broader water infrastructure, particularly dangerous.
The potential for cascading failures within interconnected power and water systems further exacerbates the risk. Many desalination plants are linked to power stations, meaning damage to one facility can disrupt the other, leading to widespread outages. This interconnectedness, combined with the region’s already precarious water situation, creates a scenario where even a limited strike could have far-reaching and devastating consequences.
Past conflicts have demonstrated this vulnerability. During the 1990-1991 Gulf War, retreating Iraqi forces sabotaged Kuwaiti power stations and desalination facilities, leaving the country largely without fresh water for years. More recently, Yemen’s Houthi rebels have targeted Saudi desalination plants, highlighting the ongoing threat to these critical facilities.
Looking Ahead
The situation remains highly volatile. The U.S. And its allies have long recognized the vulnerability of desalination infrastructure in the Gulf, as highlighted in a 2010 CIA analysis. While Saudi Arabia and the UAE have invested in redundancy measures, smaller states like Bahrain, Qatar, and Kuwait have limited backup supplies. The immediate focus remains on de-escalation and diplomatic efforts to prevent further attacks and protect critical infrastructure. The next key development will likely be the response from Iran and its regional allies to the latest round of strikes, and whether diplomatic channels can be reopened to address the underlying tensions.
