US Treasury Secretary Scott Bessent announced that Washington will impose what he called the toughest-ever sanctions aimed at collapsing Iran's economy, marking a shift toward economic isolation as a central US strategy in its confrontation with Tehran. Analysts note the move signals an intensified push to cripple Iran's financial system alongside military and diplomatic pressure. The sanctions push has drawn mixed international responses. Georgia has declined to join the European Union's latest round of sanctions against Iran, with a representative of the ruling Georgian Dream party saying Tbilisi's foreign policy decisions are guided by national interest rather than following EU or US-led measures uniformly, highlighting cracks in international consensus on isolating Tehran economically.
