What International Law Says About Trump's Threats to Bomb Iran's Bridges and Power Plants

Why It Matters

The analysis highlights the legal exposure of U.S. officials and troops to war‑crime liability, emphasizing the need for strict adherence to the law of war in any Iranian strike planning.

Key Takeaways

• Threats to destroy civilian infrastructure breach war‑crime rules
• Indiscriminate attacks violate proportionality and distinction principles
• Each target requires case‑by‑case lawful military objective analysis
• Commanders must filter orders through legal training and oath
• War crimes have universal jurisdiction, no statute of limitations

Pulse Analysis

President Donald Trump's recent public threats to bomb every bridge and power plant in Iran have reignited a debate that extends beyond politics into the realm of international humanitarian law. Under the law of armed conflict, both U.S. statutes and treaties such as the Geneva Conventions prohibit attacks that are indiscriminate or intended to terrorize civilian populations. Retired Lieutenant Colonel Rachel VanLandingham, a former Air Force officer and law professor, argues that the rhetoric alone may satisfy the legal definition of a war crime, because it signals an intent to target essential civilian infrastructure without a specific military justification.

The core principles of distinction and proportionality require commanders to separate civilian objects from legitimate military targets and to ensure that any anticipated civilian harm is not excessive relative to the concrete military advantage. VanLandingham emphasizes that bridges or power stations may become lawful objectives only after a rigorous, case‑by‑case assessment demonstrating a direct contribution to enemy operations. She cites the U.S. State Department’s condemnation of Russia’s winter attacks on Ukrainian power grids as a recent illustration of how indiscriminate strikes on civilian utilities breach both customary international law and U.S. statutes.

For U.S. forces, the practical implication is clear: any order to strike Iran’s nationwide infrastructure must be filtered through the chain of command’s legal review and the service members’ oath to uphold the Constitution. Failure to conduct proportionality and necessity analyses could expose individuals and commanders to universal jurisdiction prosecutions, which have no statute of limitations. VanLandingham advises senior officers to rely on established targeting protocols and to reject politically‑driven directives that ignore the law of war, thereby preserving both operational legitimacy and moral authority.
