On the geopolitical front, the U.S. is aggressively escalating its economic posture, with the Treasury Department announcing impending 'toughest' sanctions against Iran—formally reclassifying Hezbollah as an arm of the IRGC rather than an independent actor—while simultaneously imposing new duties on Canadian motor vehicles, dairy, and alcohol.
