Trump announces 'economic warfare' against Iran, warns countries of consequences

On August 20, 2026, U.S. President Donald Trump announced what he called an 'unprecedented' and 'most crushing economic operation ever' against Iran, describing it as 'economic warfare.' He warned that any country supporting Iran would face 'tremendous economic consequences.' U.S. Treasury Secretary echoed this warning, saying countries maintaining ties with Iran would face economic repercussions.

However, experts and analysts quoted in coverage question the impact and enforcement of these measures. The announcement raises questions about how the U.S. will implement such broad economic pressure and whether it will effectively change the behavior of other nations.
