U.S. and Iran Near 60-Day Peace Framework to End 100-Day War

After more than 100 days of direct military conflict that has reshaped the Middle East and disrupted global energy markets, the United States and Iran are on the precipice of a fragile peace agreement. President Donald Trump announced that a memorandum of understanding is scheduled to be signed on Sunday, a move he claims will immediately reopen the critical Strait of Hormuz to global shipping. The proposed signing date coincides with the U.S. president's 80th birthday, adding a layer of symbolic timing to the high-stakes diplomacy.[1][3][5]

The emerging agreement is not a comprehensive peace treaty, but rather a preliminary framework designed to de-escalate immediate hostilities and create space for broader negotiations. According to diplomatic sources, the signing would trigger a 60-day ceasefire window. During this period, the core mechanism involves a synchronized stand-down: the U.S. would lift its crippling naval blockade on Iranian ports, while Tehran would reopen the Strait of Hormuz to commercial vessels without charging transit fees.[5][6][9]

The Strait of Hormuz serves as the transit chokepoint for roughly a fifth of the world's daily oil consumption. Iran effectively closed the strait shortly after the war began in late February, deploying mines and drone swarms that virtually shut down oil and natural gas shipments. The U.S. responded by blockading Iranian ports, leading to a grueling economic and military standoff that has battered global markets.[1][6][7]

Trump has framed the impending memorandum as a definitive end to Iran's nuclear ambitions, describing the deal as a "wall to no nuclear weapon." He asserted over the weekend that Iran has agreed to abandon its pursuit of nuclear arms entirely, whether through domestic development or foreign procurement. However, the actual mechanism for ensuring this disarmament remains a subject of intense, ongoing negotiation rather than a settled fact.[1][6][8][10]

While the White House and Pakistani mediators—who have played a central role in brokering the talks—expressed confidence in a Sunday electronic signing, Tehran has forcefully pushed back on the timeline. Iranian Foreign Ministry spokesperson Esmaeil Baghaei stated that no final agreement would be signed on Sunday, characterizing the current text as merely a framework for continuing talks. "As for the exact timing of the memorandum's signing, we must wait," Baghaei said, though he did not rule out a signing in the coming days.[4][5][6][8]

A major area of uncertainty and conflicting claims revolves around $24 billion in Iranian assets currently frozen under U.S. sanctions. The U.S. administration, including Vice President JD Vance, insists that no money will be released upfront simply for signing the memorandum or attending meetings. Washington maintains that any economic benefits will only flow if Iran meets strict, verifiable obligations over the 60-day window.[1][6]

Conversely, Iranian officials maintain that the unfreezing of these funds is an "integral" condition of any lasting agreement. Tehran has demanded access to the $24 billion during the initial 60-day period, along with immediate upfront economic relief. This fundamental disconnect over the sequencing of sanctions relief versus nuclear compliance threatens to complicate the technical-level talks scheduled to follow the initial signing.[6][7]

The prospect of an agreement has ignited fierce domestic opposition within Iran, complicating the negotiating team's mandate. Over the weekend, dozens of protesters gathered outside a foreign ministry office in the northeastern city of Mashhad, chanting slogans against Foreign Minister Abbas Araghchi. Hardline factions argue that reopening the Strait of Hormuz deprives Tehran of its most potent strategic leverage and accuse negotiators of making unacceptable concessions to Washington.[8]

For Iranian hardliners, the waterway is not just a transit route but a primary instrument of deterrence. Araghchi attempted to assuage these concerns in a televised interview, noting that the administration of the Strait of Hormuz "will no longer be the same as before" and emphasizing that the deal requires the lifting of the U.S. naval blockade. Nevertheless, the domestic backlash highlights the political tightrope Tehran's leadership is walking.[8]

The framework has also triggered deep alarm in Israel, introducing another layer of regional complexity. While Prime Minister Benjamin Netanyahu previously stated he was in "full agreement" with Trump on the necessity of preventing a nuclear Iran, senior Israeli officials have warned that the reported terms of the memorandum could severely endanger national security. The Israeli security cabinet is expected to convene to discuss the ramifications of the U.S. concessions.[9]

A critical unresolved issue driving Israeli anxiety is the geographic scope of the ceasefire. Iranian sources indicate that Tehran is demanding the cessation of hostilities on all fronts, including in Lebanon. Israel has been engaged in heavy fighting with the Iran-backed Hezbollah militia, recently announcing the elimination of multiple Hezbollah field commanders. It remains unclear if the U.S. can guarantee a broader regional truce that restrains Israeli military operations in the Levant.[2][9]

Adding to the technical complexity of the nuclear file, Trump suggested that the U.S. would eventually recover and destroy highly enriched uranium buried deep underground in Iran once the region is calmer. This references the U.S. B-2 bomber strikes carried out earlier in the conflict, which targeted subterranean nuclear facilities. Tehran has not publicly agreed to any physical removal of its nuclear material by American forces, making this a likely flashpoint in future talks.[7][11]

The logistical implementation of the peace deal will rely heavily on international partners. Pakistan has emerged as the primary conduit for the negotiations, with Prime Minister Shehbaz Sharif preparing Islamabad to host the electronic signing and subsequent technical discussions. Sharif has been a vocal proponent of the deal, publicly touting that an agreement was imminent and ready for signatures.[1][7][8]

European allies are also preparing to step in once the ink is dry. British Prime Minister Keir Starmer and French officials have signaled readiness to assist in implementing the agreement, specifically by deploying military vessels to help demine the Strait of Hormuz. Restoring freedom of navigation is a top priority for European capitals, which have suffered significant economic blowback from the disruption of global energy supplies.[7][11]

Despite the diplomatic progress, the situation on the water remains highly volatile. Just hours before the proposed Sunday signing, the U.S. military shot down several Iranian attack drones in the Strait of Hormuz. The drones were apparently targeting commercial ships, eliciting a sharp response from Trump, who called the drone activity "totally unacceptable."[2][8]

If the memorandum is signed—whether on Sunday or later in the week—it will merely mark the beginning of a grueling diplomatic sprint. Negotiators will have 60 days to bridge massive gaps on sanctions relief, nuclear decommissioning, and the funding of proxy militias. Both sides will have to navigate intense domestic political pressure, proving that while ending a 100-day war is difficult, securing a lasting peace may be even harder.[6][8]
