Trump statements about Iran raise questions about international law

President Donald Trump's recent statements of intent about his administration's plans for Iran — some laced with profanity, some threatening deeply destructive, nation-shattering actions — have raised questions about international law. In his news conference on Monday, Trump threatened to blow up every bridge and power plant in Iran, an action that would be so far-reaching that some experts in military law said it could constitute a war crime. The issue could turn on whether the power plants were legitimate military targets, whether the attacks were proportional compared with what Iran has done and whether civilian casualties were minimized.
