The Iran war risks reigniting after the U.S. tried to force open the Strait of Hormuz for commercial shipping, firing on Iranian forces and sinking six small boats targeting ships. But the shaky ceasefire seemed to hold Tuesday even after the United Arab Emirates said Iran fired missiles and drones at it. The U.S. aims to end Iran’s control of the strait by creating an “enhanced security area.” Two American-flagged merchant ships successfully transited the strait on Monday. Iran’s closure of the strait has sent fuel prices skyrocketing and rattled the global economy.
