Pakistan's Improbable Moment: Can Islamabad Actually Broker Peace Between Washington and Tehran?

Two weeks ago, Field Marshal Asim Munir — Pakistan's army chief, intelligence veteran, and now the most consequential diplomatic figure Islamabad has produced in a generation — flew to Tehran. He carried what officials described as a new message from Washington. Iran's ambassador to Pakistan had declared just days earlier that Tehran would "do talks in Pakistan and nowhere else, because we trust Pakistan," according to Al Jazeera¹. And yet, as I write this on April 22, Iran has informed Pakistani intermediaries that it will not be sending a delegation for the second round of talks, citing the US naval blockade of its ports as a ceasefire violation. Trump extended the ceasefire at Pakistan's request. The talks have not resumed.

So here is the question worth untangling: is Pakistan's mediation role a genuine strategic asset, or is Islamabad manufacturing relevance it cannot sustain?

I think the answer is both, and the proportions matter enormously.

The channel is real. Start with the facts that are not in dispute. Pakistan has served as Iran's protecting power in the United States since 1992 — Iran's Interests Section physically operates out of the Pakistani Embassy in Washington, DC². That is not a symbolic arrangement. It means Pakistani diplomats have, for over three decades, been the institutional conduit for Iranian consular and quasi-diplomatic functions on American soil. When people ask how Pakistan got into this mediation game, that is the unglamorous infrastructure underneath it.

Then there is the personal dimension. Munir, before becoming army chief in 2022, led both Pakistan's Military Intelligence and the Inter-Services Intelligence (ISI). A retired Pakistani general told Fox News Digital³ that Munir maintained personal relationships with high-ranking Iranian figures, including the late Quds Force commander Qassem Soleimani and IRGC commander Hossein Salami. On the American side, the Munir-Trump relationship solidified during the May 2025 India-Pakistan crisis, where Munir was credited with helping de-escalate tensions. Trump has publicly called him "my favourite field marshal" on at least ten occasions⁴ since June 2025.

This is not the profile of a country bluffing its way into a room. Pakistan delivered a 15-point US proposal to Iran on March 25. It produced a five-point initiative for peace on March 31, followed by a 45-day ceasefire framework on April 5. It brokered the April 8 ceasefire that halted forty days of US-Israeli strikes. And on April 11, Islamabad hosted the first direct, high-level, in-person engagement between US and Iranian officials since the 1979 revolution⁵ — with Vice President JD Vance, Steve Witkoff, and Jared Kushner facing parliamentary speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi across the table, and the Pakistani team led by Prime Minister Sharif, Munir, and Foreign Minister Dar sitting between them.

That is a real accomplishment. And it happened in significant part because the alternatives collapsed. Qatar — which had mediated the 2023 US-Iran prisoner exchange and years of Hamas negotiations — explicitly declined the mediation role⁶ after Iran struck Qatar's Ras Laffan LNG facilities, wiping out 17% of its production capacity. Oman, which facilitated the 2013 nuclear back-channel and the February 2026 indirect talks in Muscat, criticized the US strikes⁷ as having occurred while negotiations were ongoing — a diplomatic protest that constrained its continued role. Pakistan stepped into a vacuum that was not manufactured; it was real.

But the limits are already visible. The April 12 talks lasted 21 hours and ended without an agreement. Vance left Pakistan saying no deal had been reached because Iran would not commit to forgoing nuclear weapons. The US immediately imposed a naval blockade on Iranian ports. Iran called the blockade an act of war. And now, as the ceasefire deadline has arrived and been extended, Iran's Tasnim news agency reports⁸ that Tehran considers attending further negotiations "a waste of time" under current conditions.

This is where the structural problem overwhelms the access advantage. Iran's core demand is not something Pakistan can deliver: an end to the US naval blockade, guarantees that Israel will stop striking Lebanon, and the lifting of sanctions. The US core demand — that Iran surrender its nuclear enrichment capacity — is not something any intermediary can broker, because Iran's decision-making apparatus is, by CNN's reporting⁹, fractured internally, with the new Supreme Leader Mojtaba Khamenei providing unclear direction and the IRGC and civilian negotiators pulling in different directions.

Pakistan can carry messages. It clearly did. But message-carrying encounters a hard ceiling when the messages themselves are unacceptable to the recipient. Barbara Slavin of the Stimson Center characterized¹⁰ Trump's ceasefire extension as "a way to cover the embarrassment" of floundering negotiations. If that assessment is correct — and Iran's refusal to appear for round two supports it — then Pakistan's channel is generating process without substance. That is a real risk.

The deeper tension: mediator or ally? There is another complication that has received insufficient attention. On April 11, the same day Pakistan hosted the Islamabad talks, Saudi Arabia's Ministry of Defence confirmed the arrival¹¹ of Pakistani fighter jets at King Abdulaziz airbase in the Eastern Province under the Strategic Mutual Defence Agreement signed in September 2025 — an agreement that commits Pakistan and Saudi Arabia to treat aggression against one as aggression against both. Pakistan is simultaneously mediating for Iran and deploying military assets to defend a country Iran has been attacking.

A former Pakistani three-star general, speaking anonymously to Al Jazeera¹¹, put it bluntly: Pakistan can hold both roles "only if deployment remains strictly defensive, time-bound, and transparently limited. The moment the theatre shifts to offensive operations, or the perception of offensive coordination emerges, the dual role collapses."

I think this is the right framing. Pakistan's mediation is real, but it is also fragile in a way that self-interested actors rarely acknowledge. The Bill Roggio critique — that Pakistan was "a perfidious ally" in Afghanistan and that Munir's IRGC ties should be "a massive red flag" — comes from the Foundation for Defense of Democracies³, which is hawkish enough to discount, but the underlying concern is not crazy. Pakistan's track record of representing both sides' interests simultaneously, while privately serving its own, is long. The Afghan precedent matters.

So where does this leave us? Pakistan's channel produced a ceasefire and the first direct US-Iran talks in 47 years. That is a genuine diplomatic achievement. It happened because Pakistan possessed a specific combination of assets — the Munir-Trump personal relationship, decades of institutional infrastructure with Iran, non-Arab Muslim identity, and the absence of viable alternatives. The channel is real.

But the channel has also, so far, failed to produce an agreement. Iran has publicly refused to return to talks. The structural obstacles — nuclear enrichment, the Strait of Hormuz, the Lebanon question — are problems of political will and power, not communication. No intermediary resolves those. Pakistan got both sides into a room, which was hard. Keeping them there, which is harder, has not yet succeeded.

The indicator to watch is simple: does Iran actually send a delegation for a second round? If Ghalibaf and Araghchi appear in Islamabad in the coming days, Pakistan's mediation has legs. If the ceasefire expires without renewed talks — or worse, if the US resumes strikes — then Pakistan's channel will have produced a temporary pause but not a pathway to resolution. The Munir-Trump relationship gives Pakistan unusual staying power in this role, but staying power is not the same as influence over outcomes. I expect Pakistan to remain central to the process. I do not expect the process to succeed on the terms either Washington or Tehran has articulated so far.
