Donald Trump posted to Truth Social on 25 April: "If they want to talk, all they have to do is call!!!"1 The post followed his Fox News statement that he would not authorise an 18-hour flight for Steve Witkoff and Jared Kushner to meet Iran's foreign minister in Pakistan. As an operational fact, the Truth Social line establishes direct phone contact as the new US procedural condition for any engagement with Tehran.
Iran's stated condition runs in the opposite direction. Spokesperson Esmaeil Baqaei has confirmed "no meeting is planned", and Tehran continues to route through Pakistani mediation. Iran has been publicly clear it will not accept direct US contact as the modality; Washington has now been publicly clear it will not pay to send envoys. A modality dispute is categorically harder to resolve than a substance gap because each side's procedural condition is also a domestic political signal: Tehran accepting a Trump phone call concedes the supplicant framing, and Washington dispatching envoys to Pakistan concedes Iran's parity claim.
The "call us" line follows the cancellation of the Witkoff and Kushner mission that had been prepared in coordination with the Vance Islamabad 2 track now postponed. With six days remaining on the WPR clock, neither side has a face-saving exit because both have committed in public.
