President Trump threatened Monday to obliterate Iran's desalination plants, power infrastructure, and oil facilities if negotiators fail to strike a deal soon. The threat marks his most direct challenge yet to the international laws designed to protect civilians during armed conflict.
The statement arrives as the Iran conflict enters its second month and reflects Trump's stated willingness to abandon constraints on military operations that he views as obstacles to victory. Water desalination systems that Iran depends on for survival fall squarely into the category of civilian infrastructure that international humanitarian law explicitly protects.
White House press secretary Karoline Leavitt said Iran's "best move is to make a deal," adding that the U.S. possesses "capabilities beyond their wildest imagination." She insisted the administration would "always act in the confines of the law" while pursuing what she called the "full objectives" of the operation.
A senior U.S. official told Axios the strikes would serve as negotiating leverage. The official suggested Iran's broken economy means a handful of sorties could cripple the nation's power grid and water supply, creating pressure to reach accommodation. The same official noted Trump objected when Israel recently targeted Iranian desalination plants, suggesting the president wants operations to remain "proportionate."
Dismantling the Guardrails
Trump's position sits atop a broader demolition of military legal constraints that his administration has pursued since taking office. Defense Secretary Pete Hegseth has systematically removed the lawyers and oversight mechanisms meant to prevent war crimes.
In March, Hegseth declared "no quarter, no mercy for our enemies" at a Pentagon briefing, using language that the Pentagon's own Law of War Manual identifies as describing a war crime. He has not retracted the statement.
Hegseth fired the top military lawyers for the Army, Navy and Air Force, saying he opposed creating "roadblocks to orders given by a commander in chief." He dissolved the Pentagon's civilian harm mitigation program, which had stationed roughly 200 personnel across military commands to prevent deaths of non-combatants.
The dissolution of that oversight function drew renewed attention after a U.S. airstrike on the war's opening day killed more than 165 people, predominantly girls, at an elementary school in the Iranian city of Minab. Trump initially denied American responsibility, falsely suggesting Iran or another party had obtained Tomahawk missiles. A Pentagon investigation later determined the U.S. was responsible, though no official findings have been released.
Hegseth also moved to punish Senator Mark Kelly, a Democrat from Arizona, for a video encouraging troops to refuse illegal orders.
The shift toward unrestricted warfare mirrors Trump's rhetoric from his 2016 campaign, when he criticized the Geneva Conventions and soldiers he claimed were "afraid to fight." He promised to reinstate waterboarding and "a hell of a lot worse." After winning office in 2016, Trump pardoned soldiers convicted of war crimes in 2019, citing Hegseth's advocacy in his decision. In his 2024 book, Hegseth wrote that troops "should not fight by rules written by dignified men in mahogany rooms eighty years ago."
Trump stated his intent plainly in remarks about the desalination threat, framing strikes as "retribution for our many soldiers" that Iran has allegedly killed over 47 years. International law explicitly prohibits reprisals against civilian populations as a form of collective punishment.
The desalination threat may prove rhetorical, a tool designed purely to extract concessions. But legal experts say it reflects a consistent pattern of statements and military decisions that contradict international armed conflict law.
The approach extends beyond Iran. The U.S. has killed more than 160 people in strikes on alleged drug trafficking boats in the Western Hemisphere since September 2025, providing minimal public justification for the targeting decisions. Last year, Trump's administration sanctioned International Criminal Court officials investigating American and Israeli nationals for potential war crimes.
