As Pompeo noted in his speech to Iranian-Americans and others in California on Sunday, the centerpiece will be the re-imposition of U.S. economic sanctions; the first batch will go back into force on Aug. 4 targeting the Iranian automotive sector and trade in gold and other metals. A more significant set of sanctions that will hit Iran's oil industry and central bank by punishing countries and companies that do business with them will resume on Nov. 4.
