Iran's militant and unyielding supreme leader, Ayatollah Ali Khamenei, who ruled the Islamic Republic for more than three decades and oversaw an era of harsh internal repression and confrontation with the United States and Israel, has died following the Israeli strike in Tehran, as his compound was reduced to rubble, a senior Israeli official told Fox News Digital. "Khamenei was the contemporary Middle East's longest-serving autocrat. He did not get to be that way by being a gambler. Khamenei was an ideologue, but one who ruthlessly pursued the preservation and protection of his ideology, often taking two steps forward and one step back," Behnam Ben Taleblu, senior director of FDD's Iran program, told Fox News Digital.
