Iran's ethnic fault lines offer path for US, Israel

Just over half of Iran's population is Persian, but the country of 90 million has seen less strife along ethnic lines than many of its neighbors, despite plenty of discontent against the clerical Shia government that cracked down ruthlessly on protests weeks ago. Since Israel and the United States attacked Iran on Saturday, killing supreme leader Ayatollah Ali Khamenei, Tehran has launched missiles and drones across the region and specifically targeted Iranian Kurdish groups across the border in Iraq.
