Iran has fired back at Donald Trump with a former IRGC commander claiming America's military strategy against Tehran has failed. Hossein Kanani Moghadam mocked Trump's claims over the Strait of Hormuz, accusing the U.S. president of lying and arguing that Washington's shift toward economic pressure signals the start of a new Cold War. He also claimed Iran retains vast missile reserves, dispersed production facilities and enough financial resources to withstand prolonged pressure. But his starkest warning involved Tehran potentially withdrawing from the NPT. Is Iran preparing its biggest nuclear challenge yet?
