Trump Announces 'Economic D-Day' Against Iran; Tehran Rejects Threat as 'Diversion'

August 20, 2026 — Three days after the June 17 Islamabad MOU's 60-day negotiating window lapsed unrenewed (Aug 17), President Trump announced what he called an 'economic D-Day' against Iran — a pledge of 'the most crushing economic operation ever taken against any country,' including new secondary sanctions targeting nations and firms, explicitly naming China and India as major buyers of Iranian oil, that help Tehran evade existing sanctions. Iranian Foreign Minister Abbas Araghchi dismissed the threat the same day as a 'diversion' from America's own debt and economic troubles, warning it would 'only bring further defeat' for the US and accusing Washington of 'economic terrorism' threatening the global economy. Oil prices rose more than 2% (to roughly $94/barrel) on the announcement. Trump reiterated the campaign's goal on Aug 21: forcing Iran to abandon its nuclear program and fully reopen the Strait of Hormuz to tanker traffic, which remains at single-digit daily crossings since the MOU deadline expired.
