Five weeks ago, the United States and Israel launched surprise strikes on Iran that killed Supreme Leader Ali Khamenei and triggered the largest disruption to global oil markets since the 1970s. Since then, two parallel tracks have run simultaneously: intensifying military operations that have killed over 7,300 people and a fragile diplomatic effort, led by Pakistan, to get the two sides talking. On April 4, Iran's foreign minister publicly denied reports that Tehran had refused to attend Pakistan-hosted negotiations, calling the reports a misrepresentation and keeping the diplomatic channel nominally alive.

The stakes extend far beyond the battlefield. Iran's closure of the Strait of Hormuz has removed roughly 20 percent of global oil supply from the market, pushing crude prices above $126 per barrel and threatening a worldwide recession. President Trump has set an April 6 deadline for Iran to reopen the strait or face strikes on its power grid and bridges. Whether the Pakistan-mediated diplomatic track can produce a framework before that deadline — or whether escalation overtakes negotiation — is the central question of this crisis.
Why it matters
One-fifth of the world's oil is blocked, crude has topped $126 a barrel, and a global recession looms unless diplomacy breaks through.

Scenarios
1
Pakistan-brokered framework produces a ceasefire and Hormuz reopening
Discussed by: Al Jazeera analysts, Christian Science Monitor, Pakistan Today — citing backchannel progress and both sides' endorsement of Pakistan as facilitator
Araghchi's public insistence that Iran never refused Islamabad talks could be a signal that Tehran is keeping the door open for a face-saving climb-down. If Pakistan can bridge the gap between the US 15-point plan and Iran's five conditions — perhaps through a phased approach where a ceasefire and partial Hormuz reopening come first, with nuclear and reparations issues deferred — a framework could emerge before or shortly after the April 6 deadline. The four-nation coalition provides multiple channels and alternative venues if Islamabad proves politically difficult.
2
April 6 deadline passes, US strikes Iranian infrastructure, war intensifies
Discussed by: NPR, Axios, Washington Times — based on Trump's repeated threats and the pattern of escalation
Trump has already extended the deadline twice. If he follows through on April 6, strikes on Iran's power grid and bridges would represent a major escalation from military targets to civilian infrastructure, likely ending any near-term diplomatic track. Iran would likely intensify its own attacks on Gulf energy infrastructure and US assets. Oil prices could spike well beyond $130 per barrel, and the economic shock could tip major economies into recession.
3
Prolonged war of attrition with intermittent, inconclusive talks
Discussed by: CSIS, Atlantic Council, The Diplomat — noting the wide gap between US and Iranian demands and the Korean War parallel of fighting-while-talking
The most historically consistent outcome. The US and Iran remain too far apart on core demands — Washington wants Iran's nuclear program dismantled; Tehran wants reparations and Hormuz sovereignty — for a quick resolution. But neither side can deliver a knockout blow. The war settles into a pattern of military pressure punctuated by periodic mediation rounds, with Pakistan, Turkey, and Egypt rotating as intermediaries. The Strait of Hormuz remains partially or fully closed for months, reshaping global energy markets.
4
China or a major external power brokers a deal outside the Pakistan framework
Discussed by: The Diplomat, The National, Al Jazeera — noting Dar's Beijing visit and China-Pakistan joint initiative
Pakistan's Ishaq Dar visited Beijing in late March, and China issued a joint initiative with Pakistan. China's leverage as Iran's largest oil customer and a major US trading partner gives it unique economic tools. If the Islamabad track stalls completely, Beijing could step in with security guarantees or an economic package that neither the US nor regional mediators can offer, potentially reshaping the diplomatic architecture entirely.
Historical Context
Oman's secret backchannel to the Iran nuclear deal (2012-2015)
July 2012 – July 2015
What Happened
Sultan Qaboos of Oman hosted at least five secret meetings between senior US officials — Deputy Secretary of State William Burns and adviser Jake Sullivan — and Iranian counterparts in Muscat. Both sides denied the talks existed for over a year. The backchannel built the framework that became the 2015 Joint Comprehensive Plan of Action, which froze Iran's nuclear program in exchange for sanctions relief.
Outcome
Short Term
The secret meetings produced enough trust to move quickly when Iran elected moderate president Hassan Rouhani in June 2013, enabling a public interim agreement by November.
Long Term
The JCPOA held from 2015 to 2018 before the first Trump administration withdrew. It proved that US-Iran agreements are possible through regional mediators — but also that they can be undone by political change in Washington.
Why It's Relevant Today
Pakistan in 2026 occupies the same structural role Oman played in 2012: a neighbor with credibility on both sides facilitating deniable contact. Araghchi's public denial of a breakdown mirrors how backchannel diplomacy typically functions — public denials often signal ongoing private engagement, not its absence.
Korean War armistice negotiations (1951-1953)
July 1951 – July 1953
What Happened
Armistice talks between UN Command and North Korean-Chinese forces lasted two years and 575 meetings at Panmunjom, while fighting continued throughout. The talks were formally suspended for 199 days at one point. Both sides used military offensives to strengthen their negotiating position. India's diplomat V.K. Krishna Menon ultimately broke the deadlock by proposing a prisoner repatriation formula that neither belligerent could have offered without appearing to concede.
Outcome
Short Term
The armistice established a demilitarized zone roughly where the war started. Neither side 'won' in traditional terms.
Long Term
The armistice was never replaced by a peace treaty and remains in effect 73 years later — a reminder that 'temporary' ceasefire arrangements can become permanent.
Why It's Relevant Today
The Korean precedent shows that theatrical breakdowns in negotiations — including long suspensions — are normal when talks run alongside active combat. The Wall Street Journal's 'dead end' report and Araghchi's denial may be part of this same pattern: public posturing that coexists with continued behind-the-scenes contact. It also suggests Pakistan's ultimate contribution may be a specific face-saving formula, not just a venue.
Algeria's mediation of the Iran hostage crisis (1980-1981)
September 1980 – January 1981
What Happened
With no diplomatic relations between the US and Iran, Algeria served as physical intermediary for four months, shuttling documents and proposals between Washington and Tehran to resolve the 444-day hostage crisis. Algerian Deputy Foreign Minister Redha Malek designed a financial escrow mechanism through the Bank of England and Algeria's central bank to unfreeze approximately $8 billion in Iranian assets, giving both sides a technical structure that obscured what was politically a difficult concession.
Outcome
Short Term
The Algiers Accords were signed January 19, 1981, and 52 hostages were released the following day.
Long Term
The Iran-US Claims Tribunal established by the accords continued operating in The Hague for decades. The model proved that financial architecture designed by a mediator can resolve disputes where direct concession is politically impossible.
Why It's Relevant Today
Algeria worked because it was ideologically sympathetic to Iran but pragmatically credible to Washington — precisely the balance Pakistan occupies today. The case suggests that if the current impasse is partly about face-saving, Pakistan's contribution may need to be a specific mechanism (sequencing of sanctions relief, Hormuz reopening protocols, verification arrangements) rather than simply hosting talks.
