How the U.S. Can Cripple Iran’s Rulers from a Distance

The killing in Iran continues, and it seems for the moment that the regime has the upper hand. Despite threats from Washington, the U.S has not yet taken military action—whether because the president has decided against it or because the necessary forces have not yet been brought into position. Skeptics of American intervention have argued that it could take much more than a few airstrikes to bring down the ayatollahs. But Edward Luttwak points to the weak state of the regime, and the possibility that Iran’s conventional army could topple it “if, and only if, the Revolutionary Guards are first targeted by the U.S.”
