Donald Trump says "MOST CRUSHING ECONOMIC OPERATION" against Iran

President Donald Trump said the United States would launch a far-reaching financial crackdown on Iran after diplomatic efforts came to a standstill, calling the move an exceptionally tough economic step. In an August 20 post on Truth Social, he said Iran had passed up an offer to negotiate and warned that countries providing any assistance through banking, commerce, airport operations, or government channels would face serious consequences. He said the campaign would target smuggled oil, cash transfers, currency-exchange services, vessel registrations, and companies used as fronts for Iranian activity, and he called on American allies to support the isolation effort. The possible impact on major economies with Iranian ties, especially China, was not immediately clear.
