President Donald Trump has unveiled what he calls the most aggressive economic campaign ever directed at a single country, announcing a sweeping new sanctions offensive against Iran that threatens to penalize any nation doing business with Tehran.

Trump made the announcement on Truth Social on August 19, characterizing the effort as “the MOST CRUSHING ECONOMIC OPERATION EVER TAKEN AGAINST ANY COUNTRY” and framing it explicitly as economic warfare. The campaign, dubbed “Operation Economic Fury,” represents a deliberate pivot away from military options and toward financial strangulation as the primary tool of US foreign policy toward Iran.

The new initiative builds on an already extensive sanctions architecture targeting more than 1,000 entities, including vessels and aircraft linked to Iran’s economy. But the real teeth of the announcement lie in the secondary sanctions threat: Trump warned that any country providing “financial lifelines” to Iran would face what he described as “TREMENDOUS Economic Consequences.”

No specific new sanctions designations or tariff schedules were detailed in the announcement itself. The move appears to be, at this stage, a declaration of intent and a public warning shot aimed at Iran’s remaining trade partners.
