President Donald Trump on Wednesday issued a stern warning to any nation thinking about offering a lifeline to Iran after announcing the launch of a U.S. operation he likened to an "economic D-Day."

"Today, I am announcing the MOST CRUSHING ECONOMIC OPERATION EVER TAKEN AGAINST ANY COUNTRY! This will be Economic Warfare and Isolation on an unprecedented scale," Trump wrote on Truth Social. "I am also announcing that ANY country that allows its financial institutions, businesses, airports, or government entities to provide any type of lifeline to Iran will itself face TREMENDOUS Economic Consequences."

"Oil smuggling, swap lines, cash transfers, exchange houses, ship registries, front companies — It all needs to stop NOW," he continued. "You know who you are. This will be an ECONOMIC D-DAY, and we need all of our Allies to stand with the United States of America to isolate, and defeat, the Iran threat. These maniacs are on the ropes, and these HISTORIC MEASURES will cripple them and their ability to project terror worldwide."
