Why the US believes Iran’s leadership is struggling despite their bluster

Washington: The US-Israeli war against Iran has fractured the Iranian government, complicating its ability to make decisions and coordinate larger retaliatory attacks, according to officials familiar with US and Western intelligence assessments.
Several dozen Iranian leaders and their deputies have been killed since the war began four weeks ago. Those who survive have had difficulty communicating and are unable to meet in person, for fear of having their calls intercepted by the United States or Israel and being targeted in an airstrike.
