Pakistan has positioned itself at the epicenter of global diplomacy as Rawalpindi attempts to broker an end to the destructive war between the United States, Israel, and Iran. On May 22, Pakistan Army Chief Field Marshal Asim Munir arrived in Tehran for an urgent, late-night huddle with Iranian Foreign Minister Abbas Araghchi and President Masoud Pezeshkian. The high-stakes visit, Munir’s second to Iran in just over a month, underscores a desperate bid to rescue a fragile April ceasefire that is rapidly coming unstuck.
While public communiqués speak neutrally of diplomatic initiatives to prevent escalation, the reality on the ground is far more perilous. The Donald Trump administration is actively preparing a fresh round of military strikes against Iranian targets, while US Secretary of State Marco Rubio openly rallies NATO allies for a militarized "Plan B" to forcefully reopen the blocked Strait of Hormuz.
The Broker of Rawalpindi
The conflict, which erupted on February 28 after intensive US and Israeli joint air strikes on Iran, has plunged global energy markets into chaos. Pakistan emerged as an unexpected bridge between Washington and Tehran, leveraging its unique position as a Sunni-majority state that shares a 900-kilometer border with Iran while maintaining decades-old defense and intelligence ties with the United States.
Islamabad previously pulled off a diplomatic coup by securing a temporary cessation of hostilities on April 8, followed by hosting historic, direct peace talks between senior US and Iranian officials on April 11 and 12. Those discussions marked the first formal bilateral negotiations of their kind since the 1979 Islamic Revolution. However, the momentum has completely stalled.
Munir did not travel alone. Pakistan Interior Minister Mohsin Naqvi, a key civilian official tightly aligned with the military establishment, was already on the ground in Tehran, laying the groundwork before the Field Marshal’s arrival. The presence of Pakistan’s top military and internal security apparatus in the Iranian capital signals that this is not a routine diplomatic exchange. It is a mathematical necessity for Pakistan, whose own fragile economy cannot withstand a prolonged regional war that drives up fuel costs and threatens border security.
The Choke Point and the Centrifuges
Two intractable issues have paralyzed the negotiation track, rendering previous agreements functionally obsolete.
- The Strait of Hormuz: Since late February, shipping through this vital maritime artery—which typically handles roughly 20% of the world’s petroleum liquids—has been effectively paralyzed. Iran refuses to open the channel unconditionally, viewing its control over the waterway as its ultimate leverage against Western military action.
- The Nuclear Stumbling Block: Tehran is resisting US demands to dismantle key elements of its nuclear infrastructure as a prerequisite for permanent sanctions relief.
Iranian Foreign Ministry spokesperson Esmaeil Baghaei explicitly detailed the deep distrust hovering over the negotiating table, pointing out that Iran has twice agreed to limits on its nuclear program, only to see Western commitments dissolve into conflict. Tehran remains dug into its 14-point proposal, insisting on its rights under the Nuclear Non-Proliferation Treaty while refusing to negotiate under the immediate threat of bombardment.
The friction is compounded by Washington’s shifting red lines. While President Trump recently noted that the US temporarily held back on renewing air strikes following explicit appeals from Gulf Arab leaders, the window for diplomacy is closing.
The Logistics of Plan B
The threat of a collapsed backchannel is already altering Western military positioning. Marco Rubio’s discussions with NATO counterparts in Sweden reveal that the alliance is no longer willing to wait out the Pakistani mediation track indefinitely.
A forced reopening of the Strait of Hormuz would require a massive international naval escort operation, an undertaking fraught with tactical risks given Iran’s sophisticated anti-ship missile inventory and drone capabilities. Despite reports that Iran has managed to down significant numbers of Western surveillance assets, the sheer asymmetry of a sustained US naval and air campaign remains a catastrophic prospect for the region.
General Munir’s midnight diplomacy in Tehran is less about achieving a grand bargain and more about preventing a catastrophic miscalculation. With the US military finalizing strike options and Iran refusing to blink on its maritime blockade, the backchannel managed by Pakistan represents the final operational buffer against an unrestricted regional war.
