Donald Trump warns IranUS President Donald Trump on Wednesday announced what he called the “most crushing economic operation” ever imposed against a country, targeting Iran with an unprecedented campaign of economic warfare and isolation while warning nations providing Tehran with financial or commercial support of “tremendous” consequences. Trump said the new measures would target any country whose financial institutions, businesses, airports or government entities provide what he described as a “lifeline” to Iran.

“No one has given the Islamic Republic of Iran a greater opportunity to make a Deal than me. TRAGICALLY, for them, they have failed to take it.

Therefore, today, I am announcing the MOST CRUSHING ECONOMIC OPERATION EVER TAKEN AGAINST ANY COUNTRY! “Today, 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. You know who you are,” he said.

The announcement marks a further escalation of Washington's economic campaign against Tehran as the US war with Iran approaches its sixth month, with the dispute over the Strait of Hormuz continuing to complicate efforts to reach a broader settlement. “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,” Trump said. “Their navy is gone, their air force is destroyed, their military factories are now rubble, their currency is worthless, and their country is hanging by a thread,” Trump said.

Trump also repeated his warning over Iran's nuclear programme, saying: “IRAN WILL NEVER HAVE A NUCLEAR WEAPON.” Before the war began, China, India, Turkey, Germany, South Korea and Japan were among Iran's major trading partners.

Trump did not identify any of these countries as a target of the new measures. “It will be a combination of economic isolation, like the world has never seen before,” Bessent told Newsmax last week.

The US Treasury has also been pursuing a sanctions campaign known as Operation Economic Fury, aimed at cutting off Tehran's sources of revenue through targeted measures. Trump's latest announcement appears to widen that pressure by warning not only Iranian entities but also foreign governments and businesses that continue providing financial, commercial or logistical support to Tehran.
