President Donald Trump announces a new U.S. economic campaign against Iran, describing it as the “most crushing economic operation ever taken.” Multiple outlets report he also warns that countries that trade with Iran will face “tremendous economic consequences.” The announcement is framed as part of Washington’s broader pressure effort as the conflict involving Iran continues.

Several reports note that markets react to the prospect of tighter U.S. economic isolation of Iran. Standard Media says oil prices fall as investors brace for details of the U.S. plan to isolate Iran’s economy. ABC News and others describe the threat in terms of an “Economic D-Day,” highlighting the president’s language about timing and impact.

While outlets differ mainly in wording—such as “economic warfare and isolation” versus “Economic D-Day”—they align on the core message: Trump is signaling expanded economic pressure on Iran and on third countries doing business with Tehran, but specific measures are not detailed in the provided summaries.
