Iran keeps behaving like an outlaw regime. Australia expelled Tehran’s ambassador last week based on intelligence that its government masterminded an attack on a synagogue in Melbourne and a kosher food company in Sydney. The head of the United Nations nuclear watchdog is receiving enhanced security because of what he calls a threat “from the direction” of Iran. On Sunday, the Iran-backed Houthis raided the offices of the World Food Program, World Health Organization and UNICEF in Yemen’s capital.
