On June 15th, Pakistan brokered a tentative halt to more than one hundred days of war between the United States and Iran. The move thrust an unlikely middle power into a role usually reserved for the world’s strongest states. Prime Minister Shehbaz Sharif announced the deal first on X, and President Donald Trump confirmed it hours later. The agreement calls for an immediate and permanent end to hostilities on all fronts, including Lebanon, and is set to be signed on Friday, June 19th; however, Israel’s rejection clouds that ambition. The terms of the agreement include the U.S. lifting its naval blockade and the reopening of the Strait of Hormuz. Pakistan, a state long dismissed as a security liability, sat at the center of these negotiations, raising the question of what a middle power can, and cannot, accomplish in the current geopolitical climate.

Pakistan’s intervention is being framed as an achievement of diplomatic stature as much as of substance. United Nations Secretary-General António Guterres labelled it a critical step towards a peaceful settlement and credited Islamabad’s role. Jauhar Saleem, a former Pakistani diplomat, offered this reading: “It’s not a question of what changed between April and June. It’s rather an example of a never give up approach in diplomacy where an honest broker respected by both sides can eventually help overcome an overwhelming trust deficit.” He added that “Pakistan’s leverage was and remains its credibility as a trusted friend and well-wisher and a fair intermediary.” Regional analysts note that Tehran deliberately preferred a mediator with no American military bases on its soil. The same commentators, however, point to the limits of that leverage. Israel, a co-belligerent, was never a party to the deal. National Security Minister Itamar Ben Gvir declared on X that the agreement does not bind it, while Defense Minister Katz refused to withdraw from southern Lebanon.

This is the paradox of the middle power, and it leads to questions about what genuine peace making requires. Pakistan can succeed as a convener precisely because it lacks coercive power. It has no stake that threatens either Washington or Tehran, nor does it menace those two nations, so it can carry messages between states that will not communicate directly. Yet the same qualities that make a middle power the trusted broker leave it unable to guarantee the peace it brokers. The result is a settlement that stops the violence by deferring its causes: a final nuclear agreement in 60 days, Iran’s missiles and proxies dropped from the agenda, and terms that largely restore the prewar status quo. Any act of de-escalation is welcome. However, a peace that postpones the hardest questions is shallow, and a middle power alone cannot supply the depth it needs.

Pakistan’s emergence is part of a longer geopolitical repositioning. The war began on February 28th with U.S. and Israeli strikes; an April ceasefire and the Islamabad talks that followed produced the highest-level direct U.S.-Iran engagement since 1979. Pakistan’s credibility rests on the fact that it hosts no U.S. bases, shares a long border and religious ties with Iran, holds a defense pact with Saudi Arabia, and has carefully cultivated its relationship with Washington. Its current role echoes 1971, when Pakistan was the conduit for Henry Kissinger’s opening to Beijing.

The deal’s fate is now largely beyond the reach of Islamabad. The G7 Leaders’ Statement issued at Évian on June 17th welcomed the agreement as secured “under the strong leadership of President Trump, with the support of mediating countries,” never naming the indispensable mediator. The same statement endorsed a French- and British-led multinational initiative to reopen the Strait of Hormuz, folded the International Atomic Energy Agency back into the diplomatic follow-on, and pledged the bloc’s support for implementation while reaffirming that Iran will never obtain a nuclear weapon. The pattern exposes the ceiling of the middle power moment: such states can initiate diplomacy once reserved for the great powers, but they cannot consummate it alone. Whether the world is witnessing a genuine redistribution of diplomatic agency, or merely a useful role bounded by hard power, will be answered in the coming weeks.
