Experts in military law have suggested that bombing Iran's infrastructure could constitute a war crime after President Donald Trump threatened to blow up every bridge and power plant in Iran. The issue hinges on whether the power plants are legitimate military targets, whether the attacks were proportional compared to Iran's actions and whether civilian casualties were minimized. The threat was so broad it did not account for the harm to civilians, leading to accusations that such strikes would violate international law. The U.N. Secretary-General Antonio Guterres warned that attacking such infrastructure is banned under international law even if it were a military objective. Michael Schmitt, a professor emeritus at the U.S. Naval War College and an international law professor at the University of Reading in Britain, said that military commanders should consider targeting a power facility that provides electricity to a military base in addition to civilians.
