T he White House isn’t wasting any time: One week after President Trump withdrew the US from the Iran nuclear deal, the Treasury Department imposed new sanctions on Iran’s central bank, labeling its head a global terrorist and accusing him of funneling money to Hezbollah. The Treasury Department also broke up a currency exchange network in Dubai that it said was directing money to the Islamic Revolutionary Guard Corps, Iran’s foreign expeditionary force. Those moves were on top of sanctions reimposed on May 8, when the United States withdrew from the Joint Comprehensive Plan of Action (JCPOA).
