Trump threatens economic consequences for any country supporting Iran

Aug 20, 2026

U.S. President Donald Trump has announced an unprecedented economic campaign against Iran, threatening "tremendous economic consequences" for any country providing a lifeline to Tehran. The announcement, which Trump termed an "Economic D-Day," comes as the US-Iran war nears its six-month mark following the expiration of a 60-day ceasefire. While Trump did not name specific targets, the move threatens to disrupt trade with China, which purchases over 80% of Iran's shipped oil. Iranian Foreign Minister Abbas Araghchi dismissed the threats as a diversion from U.S. domestic debt crises.
