Iran Refuses Compromise as Pakistan Mediates U.S. Nuclear Talks

CNBC reported Saturday that Iran’s chief negotiator declared Tehran would make no concessions in ongoing diplomacy with Washington, deepening uncertainty over a fragile ceasefire between the two countries.

Iran’s Hardline Position Rattles Mediation Effort

Iranian Parliament Speaker Mohammad Baqer Qalibaf met Pakistani army chief Asim Munir in Tehran on Saturday. During those talks, Qalibaf said Washington could not be trusted as a negotiating partner. He described the U.S. as lacking basic honesty, a charge Iranian officials have levelled repeatedly in recent weeks. Qalibaf also said Iran would defend its national rights both militarily and diplomatically. He warned that any U.S. decision to resume hostilities would trigger a response more severe than the conflict’s opening phase.

Pakistan Steps In to Bridge Deep Divisions

The visit by Munir is part of a broader regional push by Islamabad to mediate between Tehran and Washington. Pakistani officials held multiple sessions with Iranian Foreign Minister Abbas Araqchi as well as a separate meeting with President Masoud Pezeshkian. Talks centered on a 14-point framework document that Iran has put forward as the primary basis for any agreement. The two sides have been exchanging messages through this diplomatic channel in recent days.

Background: Ceasefire Holds, But Hormuz Remains Closed

Weeks of direct conflict between Iran and the United States preceded the current fragile ceasefire. The fighting has left the Strait of Hormuz largely closed to commercial shipping, rattling global energy markets. Iran has also retained its stockpile of near-weapons-grade enriched uranium throughout the confrontation. Its missile, drone, and proxy networks remain intact. The U.S. and Israel have both stated publicly that dismantling those capabilities is a core objective of any final deal.

Washington Signals Progress, Tehran Pushes Back

Secretary of State Marco Rubio said Friday that the U.S. sees modest movement toward a resolution but acknowledged significant work remains. Iran’s foreign ministry pushed back sharply, saying the gaps between the two sides remain wide and consequential. Markets tracking Persian Gulf shipping and oil supply routes have stayed on edge throughout the ceasefire period. Analysts warn that any breakdown in Pakistan’s mediation effort could quickly reignite hostilities and further disrupt energy flows through one of the world’s most critical maritime chokepoints.
