US and Iran announce landmark deal to end military operations; signing set for Friday

Ongoing conflict in Lebanon with two failed ceasefires; unclear if agreement will provide relief to affected civilian populations.
Iran stepped back from another missile attack to preserve the deal
The agreement nearly collapsed when Israel struck Beirut, but Tehran chose negotiation over escalation.

After decades of enmity and months of escalating confrontation, the United States and Iran have arrived at a peace agreement to be formally signed in Switzerland, brokered through Qatar's patient mediation. The deal seeks to quiet multiple theaters of conflict, reopen the arteries of global commerce, and begin the longer work of unwinding sanctions and nuclear tensions. Markets have already responded, and world leaders have offered cautious welcome — yet the agreement's durability rests on forces neither Washington nor Tehran fully controls, chief among them an Israel that has not agreed to stop fighting in Lebanon.

  • Fourteen to fifteen hours of continuous talks in Tehran produced a finalized memorandum, with Iran's amendments accepted and both sides rushing to claim the victory as their own.
  • The Strait of Hormuz closure and US port blockades — twin chokeholds on global energy supply — are set to be lifted, sending oil prices lower the moment the announcement landed.
  • The ceasefire language covering Lebanon carries a hollow ring: Israeli strikes on Beirut's southern suburbs twice nearly collapsed the negotiations, and Netanyahu has signaled no intention of halting operations against Hezbollah.
  • Iran pulled back from the edge of a fresh missile strike on Israel specifically to preserve this deal, revealing how fragile the diplomatic thread truly was in its final hours.
  • A 60-day negotiation window now opens for the harder questions — sanctions relief and Iran's nuclear program — leaving the agreement's most consequential chapters still unwritten.
  • The Friday signing in Switzerland marks a threshold, not a resolution: implementation depends on parties who were not in the room and on a region that has already watched two Lebanese ceasefires dissolve.

The United States and Iran have agreed to a peace deal, with a formal signing set for Friday in Switzerland — an announcement delivered to the world by Pakistan's Prime Minister Shehbaz Sharif. The agreement aims to halt military operations across multiple fronts, most prominently in Lebanon, and to reopen the Strait of Hormuz and Iranian ports, two passages whose closure had sent economic shockwaves far beyond the region.

The breakthrough came after nearly 14 to 15 hours of unbroken talks in Tehran, mediated by Qatar. Iran's deputy foreign minister Kazem Gharibabadi described the final session as grueling, noting that Iranian amendments to a draft memorandum were ultimately accepted. Both governments moved quickly to frame the outcome as a win: Trump declared it would bring "peace and security to the whole region," while Gharibabadi pointed to what he called Iran's military achievements. Oil markets responded immediately, and Trump suggested that once signed, "oil will flow."

The deal's most fragile element is Lebanon. The agreement calls for the "immediate and permanent termination of military operations on all fronts, including in Lebanon" — but Israel, which is not a party to the deal, has shown no sign of ending its offensive against Hezbollah. Israeli strikes on Beirut's southern suburbs twice nearly derailed the negotiations entirely, and Iran itself had been preparing another missile strike on Israel before stepping back to protect the diplomatic process. Two ceasefires in Lebanon have already collapsed, and whether ordinary Lebanese civilians will feel any relief remains an open question.

A 60-day window follows the signing for negotiations on sanctions relief and Iran's nuclear program — the issues Tehran considers most vital to its battered economy. World leaders from the UN Secretary-General to the prime ministers of Japan, Australia, and New Zealand offered measured welcome, each emphasizing the deal's importance to energy stability and regional security.

Friday's ceremony in Switzerland will be a beginning. What it begins depends on whether agreement on paper can survive contact with a region still very much at war.

After what felt like an endless cycle of near-misses and false starts, the United States and Iran have agreed to a peace deal. The formal signing will happen Friday in Switzerland, according to Pakistan's Prime Minister Shehbaz Sharif, who announced the breakthrough to the world. The agreement aims to halt military operations across multiple theaters, most notably in Lebanon, and to restore two of the world's most economically vital passages: the Strait of Hormuz, which Iran had closed, and Iranian ports, which the US had blockaded.

The deal emerged from intensive negotiations brokered by Qatar. Iran's deputy foreign minister, Kazem Gharibabadi, described the final push as grueling—nearly 14 to 15 hours of continuous talks in Tehran where Iranian negotiators presented their amendments to a draft memorandum of understanding. Those amendments were accepted, Gharibabadi told Iranian state media, and the text was finalized. The process, he acknowledged, had taken considerable time. Both sides are now claiming victory. Donald Trump declared the agreement would bring "peace and security to the whole region," while Gharibabadi highlighted what he framed as Iran's military achievements. The market reacted immediately: oil prices fell on the announcement, and Trump suggested that once the deal is signed, "oil will flow."

The agreement commits both parties to the "immediate and permanent termination of military operations on all fronts, including in Lebanon." That language, however, masks a significant complication. Israeli Prime Minister Benjamin Netanyahu has given no indication he intends to end Israel's offensive against Hezbollah in Lebanon. Twice in the past week alone, Israeli strikes on Beirut's southern suburbs—launched in response to Hezbollah rockets fired into northern Israel—nearly derailed the entire negotiation. Iran itself had been on the brink of launching another missile attack on Israel before deciding to step back to preserve the deal. Lebanon, caught in the middle, has already seen two ceasefires collapse. Whether this agreement will provide any relief to Lebanese civilians remains unclear.

The deal also establishes a 60-day window for further negotiations on critical issues, particularly the lifting of sanctions against Iran—a top priority for Tehran's struggling economy. The restoration of the Strait of Hormuz and Iranian ports, while not necessarily immediate, offers some relief to both sides: Trump gains political cover from the economic damage the blockade caused globally, and Iran's collapsing economy gets a chance to breathe.

World leaders have largely welcomed the announcement. UN Secretary-General António Guterres called it "a critical step towards the peaceful settlement of the conflict." Japan's Prime Minister Sanae Takaichi expressed hope that free navigation through the Strait of Hormuz would be secured and that a final agreement on Iran's nuclear program would follow quickly. Australia's Anthony Albanese framed the deal as essential to easing energy prices and economic pressure across the region. New Zealand's Foreign Minister Winston Peters called it a "pivotal, constructive deal" and a step toward reducing tensions in a region vital to global economic security.

What happens next depends largely on whether the parties can move from agreement to implementation—and whether Israel, which is not a signatory, will honor the ceasefire in Lebanon that the deal envisions. The signing on Friday marks a beginning, not an ending.

This Great Deal will bring Peace and Security to the whole Region
— Donald Trump
This negotiation process took a long time. Nearly 14 to 15 hours of lengthy talks took place, during which we presented the Islamic Republic of Iran's final amendments to the text.

Why did it take so long to get here? What changed?

Model

Both sides had walked away from the table multiple times. The turning point seems to be that Iran decided the cost of continued escalation—another round of missile strikes, more economic isolation—was higher than accepting a deal. And Trump wanted a win before the signing ceremony.

Inventor

But Netanyahu isn't bound by this agreement. How does that work?

Model

It doesn't, really. The deal is between Washington and Tehran. Israel is its own actor. Netanyahu has shown no willingness to stop operations against Hezbollah, which means the ceasefire in Lebanon could be dead on arrival.

Inventor

So Lebanon is still caught in the middle.

Model

Exactly. Two ceasefires have already failed. This agreement calls for ending military operations there, but if Israel doesn't comply, it's just words on paper.

Inventor

What about the sanctions? That seems to be what Iran really wanted.

Model

Yes. The 60-day negotiation period ahead is really about that. Iran's economy is in freefall. Lifting sanctions is survival for them. But the US will likely demand concessions on the nuclear program in exchange.

Inventor

And the oil markets already moved.

Model

They did. Prices fell immediately because traders believe the Strait of Hormuz will reopen and supply will increase. That's real economic relief, at least on paper.
