US-Iran sanctions rhetoric sharpens; no sanctions action or force movement seen
On 20-21 Aug 26, outlets reported Trump threatening 'economic D-Day' sanctions on Iran and Tehran vowing a 'devastating response' hours later. No sanctions authority, target list or effective date was named in reporting.
KEY JUDGMENTWe assess this exchange is coercive signalling around a sanctions threat rather than a precursor to hostilities, with a negotiating track still running; the next observable step should be economic measures, not a change in force posture.
