Why Pakistan Can't Afford to Sit Out the Iran War

The war between the United States, Israel, and Iran has become the most dangerous conflict in the Middle East this century. Now in its second month, it has also produced an unlikely diplomatic protagonist. Pakistan, a country rarely associated with Middle Eastern peacemaking, has positioned itself as the principal intermediary between Washington and Tehran, relaying demands, brokering confidence-building measures, and assembling a coalition of Sunni powers behind a ceasefire framework.
On March 31, Pakistan and China issued a five-point proposal for ending this escalating war. It called for an immediate ceasefire, peace talks, protection of civilians, the provision of humanitarian aid, reopening the Strait of Hormuz, and moving towards a comprehensive peace deal in accordance with the “purpose and principles of the United Nations charter and international law”. By joining Islamabad in presenting a roadmap to end the war, Beijing has subtly indicated that it might assume the role of a guarantor that Tehran seeks for a future agreement. The proposal capped a week of shuttle diplomacy in which Islamabad carried messages between the warring sides and convinced Tehran to allow some 20 oil tankers under its flag through Hormuz as a gesture of seriousness.
Pakistan’s centrality in this effort has surprised many observers. But Islamabad’s motivations are not altruistic. The war threatens to activate multiple fault lines that run through the Pakistani state: sectarian, economic, territorial, and strategic. Understanding why Pakistan assumed the role of mediator requires examining each of those vulnerabilities in turn.
Sectarian Fault Line
Pakistan is motivated by self-interest in seeking a peaceful end to a war in which it is not a party, but which threatens its core interests, stability, and even prospects of survival as a state. The foremost factor motivating its actions is its own Shia population. Pakistan has the largest Shia population after Iran. They constitute up to 20 percent of Pakistan’s estimated 250 million population. Islamabad endured violent protests by Shia protestors after the U.S. and Israel killed Iran’s supreme leader, Ayatollah Ali Khamenei, at the beginning of the war.
At least 30 people were killed in violent protests across the country on March 1. In the most violent single incident, at least 10 people were killed, and scores more were injured in the southern seaport city of Karachi when U.S. Marines opened fire as a mob attempted to storm the U.S. consulate. In the predominantly Shia northern region of Gilgit-Baltistan, which borders China, at least 20 people were killed, and scores more were injured when mobs burned a UN office and damaged or torched several government buildings. Islamabad imposed a curfew in Gilgit-Baltistan and cracked down hard on the protestors. Islamabad is currently pushing for trying some of the protestors in military courts for allegedly vandalizing military installations during the protests.
By cracking down hard on Shia protestors, Pakistan signaled it would not risk its Shia population mobilizing to participate in the war or protest in opposition to it. The country’s most powerful official, Chief of Defense Forces Field Marshall Asim Munir, met a group of Shia clerics on March 19. “Violence in Pakistan, on the basis of incidents occurring in another country, will not be tolerated,” he told the group, according to a handout by the Pakistani military’s media wing.
But some Shia clerics who participated in the meeting said they felt threatened and humiliated. One participant said that Munir’s comments gave the impression that the country’s dominant military establishment doesn’t trust the loyalty of Shia citizens. “We were told not to be more loyal to Iran. If we were more loyal to Iran, then we should leave Pakistan,” said Allama Syed Hasnain Abbas Gardezi, a Shia cleric in Islamabad who participated in the event.
Like Shia populations across the Middle East, Iran’s Islamic revolution inspired and mobilized Pakistan’s Shias, who are present across the country’s ethnic, class, and geographic fabric. Islamabad’s Islamization drive and its status as a harbinger of Western-funded anti-Soviet Afghan Jihad turned the country into a sectarian frontline between the Sunni and the Shia.
While Saudi Arabia funded anti-Shia Sunni political parties and their militant outfits, Iran also funded hardline Shia parties and their militant wings. During the past four decades, thousands have been killed and injured in the sectarian violence, with Shias making up most of the victims. Since at least 2013, Iran’s Islamic Revolution Guard Corps has mobilized Pakistani Shias to fight on its behalf in Syria. Thousands of members of the Zainabyoun Brigade, as the Pakistani Shia militia is formally known, have fought in Syria, which raises the possibility that they can be mobilized again to defend the Islamic Republic while it faces an existential crisis during the ongoing war.
Saudi And Gulf Connections
Closely tied to Islamabad’s complex relations with Iran’s Islamic Republic, led by Shia clerics, is Islamabad’s alliance with its archrival, Sunni Saudi Arabia. In September, Islamabad and Riyadh signed a Strategic Mutual Defense Agreement, which requires Pakistan to defend Saudi Arabia if it faces “aggression”. Yet Islamabad now wants to avoid joining the war against Tehran if Riyadh decides to retaliate against persistent Iranian attacks.
Pakistan, however, is hardly eager to join a devastating war against a Muslim neighbor with which it has enjoyed cordial, though occasionally tense, relations. For Pakistan’s powerful military leaders, joining a war, highly unpopular among its people, might prove to be a disaster. In addition, Islamabad's military posture is primarily oriented against archenemy India. Most of its air force, land forces, and navy are deployed along its eastern border with India and in the Indian Ocean. Pakistan is also currently engaged in a simmering war against its western neighbor, Afghanistan.
Islamabad has joined Riyadh, Ankara, and Cairo in a nascent Muslim bloc, which is closely watching the Israel-led effort to remake the Middle East. Unlike the United Arab Emirates, which has normalized relations with Israel under the Abrahamic Accords, these states are anxious about dealing with a possible regional hegemon if Israel succeeds in causing the demise of the Islamic Republic of Iran or severely weakens its military capabilities and regional standing. Before the war, Riyadh had already moved against curtailing Abu Dhabi’s influence. Some in Israel already see Turkey as the next Iran, while Ankara has urged the Gulf nations to weigh the risks of Israel emerging stronger from the conflict. Islamabad has not recognized Israel, but its policymakers are wary of dealing with its growing influence if it defeats Iran. For decades, they have felt threatened by New Delhi’s growing strategic ties with Israel. Indian Prime Minister Narendra Modi’s visit to Israel on the eve of its war with Iran and talk of forging a close strategic partnership raised alarm bells in Islamabad and must have raised questions in Tehran.
The economic impact of the Iran war appears to be a more immediate concern for Islamabad. Fuel prices have already doubled since the outbreak of the war. This is expected to unleash a new wave of inflation in the country, where persistent price increases are the top public issue. A prolonged war in the Gulf region could become an economic calamity for cash-strapped Islamabad. Some four million Pakistani workers, nearly half of them in Saudi Arabia, send home over $20 billion annually in remittances from the oil-rich Sunni Arab Gulf monarchies. The loss of these and trade with the Gulf would constitute an economic shock Pakistan can hardly absorb.
Balochistan
Pakistan and Iran share the vast restive region of Balochistan across their 560-mile-long border. The mineral and natural-resource-rich region, with its over 1,000-mile-long Makran coast along some of the busiest sea lanes, is divided into the poorest provinces in both countries. Since the dawn of this century, Pakistan’s southwestern Balochistan Province has been reeling from a festering separatist insurgency by secular ethnic Baloch ethnonationalists. Thousands have been killed and hundreds of thousands displaced by military operations and militant attacks. Hundreds of separatists, soldiers, and civilians were killed in the largest ever coordinated attacks earlier this year. The attacks proved that Islamabad’s relentless crackdown on the Baloch nationalist has not crushed their insurrection in the absence of a political settlement.
Iran’s southeastern province of Sistan-Baluchestan has been historically marginalized. The region's Baloch minority, who are two percent of the over 90 million population, has faced discrimination because of its status as an ethnic and linguistic minority where Persians are the majority. As Sunnis, the Baloch are also a religious minority in a predominantly Shia nation ruled by clerics of the same sect. Since 2004, successive Islamist militant groups such as Jundullah and Jaish al-Adl have attacked Iranian forces and government interests in the region.
Tehran and Islamabad have frequently accused and even attacked each other’s territories over support for Baloch rebels. Tehran has also accused Saudi Arabia, the United States, and Israel of support for Baloch militants. Islamabad accuses New Delhi of supporting the Baloch separatists. New Delhi, Riyadh, Washington, and Israel have rejected Islamabad and Tehran’s claims. Since 2024, Tehran and Islamabad have attempted some consistent cooperation against militants in their respective parts of Balochistan. Their cooperation followed tit-for-tat strikes in early 2024 in which Iran and Pakistan targeted Baloch separatists in the other country. Both accused the other of harboring Baloch separatists.
At the beginning of the current war, Israeli Prime Minister Benjamin Netanyahu called on the Baloch, Persians, Kurds, and Azeris “to join forces, topple the regime, and secure” their future. Tehran has viewed such statements and attempts to mobilize armed Kurdish separatists as a plan to fragment Iran along ethnic lines. To prevent such an outcome, Tehran has attacked Iranian Kurdish separatists in northern Iraq. Islamabad would like to avoid dealing with Iran’s fragmentation at all costs because of the perceived danger it would pose to its own cohesion. Thus, diplomacy remains a natural low-cost alternative to all the options currently available to its leaders.
The Limits of Mediation
Pakistan's diplomatic intervention is driven less by ambition than by necessity. Every dimension of the Iran war, including sectarian mobilization, Gulf economic dependence, further instability in Balochistan and the risk of Iranian fragmentation, feeds directly into Islamabad's most acute domestic vulnerabilities. Mediation is the lowest-cost instrument available to a state that cannot afford to be drawn into the conflict or to ignore it.
Whether Pakistan can sustain this role is another question. Islamabad has limited leverage over either Washington or Tehran, and its credibility as a neutral broker is complicated by its defense pact with Riyadh and its own crackdown on Shia dissent. The Chinese co-sponsorship lends weight to the ceasefire framework, but Beijing has so far avoided committing the kind of diplomatic capital. It is not clear whether Beijing will offer security guarantees, economic incentives, and enforcement mechanisms required to make a future settlement durable.
For now, Pakistan has succeeded in opening a channel where none existed. Translating that channel into a ceasefire, and a ceasefire into a negotiated settlement, will require far more than message-carrying. It will require the warring parties to see a political off-ramp as preferable to escalation. For now, neither Washington nor Tehran appears ready to make such a calculation.
