Trump Announces "Most Crushing" Iran Sanctions Six Months After Failed Ultimatum

On August 20, 2026, President Trump announced what he called "most crushing" sanctions against Iran. The move follows a February 19 ultimatum in which Trump gave Tehran 10–15 days to reach a deal or face "really bad things." No agreement materialized. No new diplomatic track has been announced with these measures. Trump said US demands remain focused on preventing Iran from obtaining nuclear weapons.
