Retired Gen. Frank McKenzie, former head of U.S. Central Command, stated on 'Face the Nation' that the U.S. could take control of the Strait of Hormuz or Iran's Kharg Island oil terminal to pressure Iran. He emphasized that direct, existential pressure is needed to gain concessions from Iran as the U.S. and Iran exchange strikes.
