Inside the U.S.-Iran Peace Deal: How the Islamabad Memorandum Halted a 110-Day War

The United States and Iran have officially signed the "Islamabad Memorandum of Understanding," bringing an abrupt halt to a 110-day military conflict that severely disrupted global energy markets and reshaped Middle Eastern alliances. Brokered primarily by Pakistan, with support from Qatar, Turkey, and Egypt, the 14-point agreement was digitally signed by U.S. President Donald Trump and Iranian President Masoud Pezeshkian. The pact immediately terminates military operations on all fronts, lifts the U.S. naval blockade on Iranian ports, and mandates the reopening of the Strait of Hormuz to international commercial shipping.[3][5]

For the global economy, the cessation of hostilities averts what President Trump described as a potential "economic catastrophe." The closure of the Strait of Hormuz—a vital maritime chokepoint through which approximately 20 percent of the world's exported oil and natural gas passes—had driven inflation higher and undermined global growth prospects. Following the announcement of the memorandum, crude oil prices experienced an immediate drop, with Brent crude falling as the threat to energy supplies receded.[5]

However, international law experts and geopolitical analysts caution that the memorandum is less a comprehensive peace treaty than a high-stakes framework to negotiate one. The document establishes a 60-day window for technical talks regarding Iran's nuclear program and its regional proxy networks, effectively deferring the conflict's most intractable issues. Because the agreement is a political understanding rather than a formal treaty requiring U.S. Senate ratification, its enforcement relies heavily on the immediate compliance and good faith of both administrations.[3][6]

The economic mechanisms embedded in the memorandum are vast and heavily front-loaded. In exchange for Iran restoring maritime traffic through the Strait of Hormuz to pre-war levels within 30 days—and allowing toll-free passage for a period of 60 days—the United States has agreed to waive sanctions on Iranian oil exports. This waiver allows Iran to immediately resume selling crude oil, petrochemical products, and related banking and insurance services on the global market.[3][5]

Furthermore, the agreement outlines the unfreezing of billions of dollars in Iranian assets held overseas and proposes the creation of a $300 billion international reconstruction fund for Iran, contingent upon Tehran signing a final nuclear pact. The U.S. has also pledged not to deploy additional troops to the region during the negotiation window, and has committed to removing its forces from the "proximity" of Iran within 30 days of a final deal being reached.[3][6]

This sudden diplomatic pivot has triggered a political earthquake in Israel, where both the government and the public feel sidelined and betrayed by their closest ally. Israeli officials had entered the joint military campaign with the expectation that it would result in the complete destruction of Iran's nuclear facilities, the dismantling of its ballistic missile program, or the collapse of the Islamic Republic's government.[2]

Instead, the memorandum leaves Iran's infrastructure largely intact. Crucially, it permits the continued domestic enrichment of uranium under International Atomic Energy Agency (IAEA) supervision, rather than forcing the surrender of all nuclear material as Washington had initially demanded at the start of the war. In cities across Israel, commentators and citizens alike have condemned the deal as a capitulation that leaves the nation surrounded by emboldened adversaries, with many expressing shock that the U.S. abandoned the military campaign so abruptly.[2][6]

The rift between Washington and Jerusalem spilled into public view this week, exposing a severe fracture in the historic alliance. U.S. Vice President JD Vance delivered a blistering rebuke to Israeli leaders who criticized the deal, telling them to "wake up and smell the reality" of their growing international isolation. Using unusually sharp language from the White House briefing room, Vance pointedly noted that American taxpayers had funded "two-thirds" of the weapons defending Israel over the past three months.[1]

Vance warned that Donald Trump remains the only world leader sympathetic to Israel's current position, signaling that the White House will not tolerate Israeli efforts to undermine the diplomatic breakthrough. U.S. intelligence agencies reportedly warned the Trump administration that Israeli Prime Minister Benjamin Netanyahu might take steps to derail the agreement, particularly as he faces intense domestic pressure to achieve a decisive military victory.[1]

The fragility of the U.S.-Iran memorandum was immediately tested by escalating violence in Lebanon. The agreement explicitly called for a cessation of hostilities on all fronts, which Washington interpreted as including the ongoing conflict between Israel and the Iran-backed militant group Hezbollah. The inclusion of Lebanon in the text effectively required Iran to rein in its most powerful proxy force, though U.S. officials clarified that Israel retained the right to strike back if attacked.[3]

When Israel launched waves of airstrikes across southern Lebanon in response to a deadly Hezbollah drone attack that killed four Israeli soldiers, the entire peace framework shuddered. Iranian officials warned that the fighting could be a "make or break" factor for the broader peace process, insisting that a ceasefire in Lebanon was essential before they would proceed with diplomatic talks. The flare-up prompted U.S. officials, including Vice President Vance, to temporarily delay their travel to the negotiations.[2][4]

Recognizing the existential threat to the negotiations, the Trump administration exerted heavy pressure on Israel to halt its northern offensive. On Friday, U.S. and Qatari mediators successfully brokered a ceasefire between Israel and Hezbollah, pulling the broader peace framework back from the brink. President Trump described the Lebanon truce as the "icing on the cake," noting in an interview that he had personally urged Israeli officials to accept the pause in fighting to clear the path for diplomacy with Tehran.[7]

With the Lebanon ceasefire holding, the diplomatic focus now shifts to Switzerland, where the grueling 60-day technical negotiations are set to begin. U.S. envoys Steve Witkoff and Jared Kushner have traveled to the Alpine nation to meet with Iranian Foreign Minister Abbas Araghchi, alongside mediators from Qatar and Pakistan.[3][4]

These technical talks will determine whether the interim economic relief and military stand-down can be converted into a permanent resolution regarding Iran's nuclear ambitions and ballistic missile programs. The negotiations will also have to address the exact schedule for lifting all remaining U.S. sanctions, a key demand from Tehran.[3][4][5]

The uncertainty surrounding the final outcome remains immense. The U.S. has maintained that it will "bomb the hell out of them" if Iran violates the terms of the agreement, keeping the threat of military force firmly on the table as leverage. Conversely, Iran views the document as a recognition of its sovereignty, a definitive end to U.S. military pressure, and a guaranteed pathway to economic recovery.[6]

If the negotiators in Switzerland cannot bridge the massive gap between these two interpretations over the next two months, the Middle East could rapidly slide back into a devastating regional war. For now, the Islamabad Memorandum stands as a fragile bridge over a chasm, halting the immediate bloodshed but leaving the underlying geopolitical tectonic plates entirely unresolved.[6]
