U.S. Signals Slight Diplomatic Movement with Iran via Pakistani Back-Channels

Secretary of State Marco Rubio confirmed on Friday that there has been "a little bit of movement" in indirect negotiations between the United States and Iran. Speaking on the status of the Trump administration's latest proposal, Rubio noted slight progress but urged caution against exaggerating the breakthrough. The negotiations are currently being facilitated by Pakistani mediators, with Tehran confirming on Thursday that it is officially considering the U.S. terms. The diplomatic track is intensifying as Pakistan's Army Chief, Field Marshal Syed Asim Munir, reportedly travels to Tehran to serve as a high-level intermediary. While regional officials suggest a "partial reduction in differences," the U.S. maintains a dual-track strategy. Rubio emphasized that military strike plans remain "fully ready" and expressed firm opposition to Iran’s attempts to implement a "tolling system" in the Strait of Hormuz, labeling the move unacceptable and threatening a "Plan B" if maritime passage is restricted. Despite the procedural movement, significant friction remains regarding the U.S. "maximum pressure" approach. Iranian officials continue to call for an end to what they term "threat-based diplomacy" as a prerequisite for further progress. For now, the channel through Islamabad remains the primary path for communication as both sides weigh their next steps in the escalating regional standoff.
