U.S. and Iran Sign Memorandum of Understanding to End 110-Day War

The United States and Iran have officially signed a 14-point Memorandum of Understanding (MOU), establishing a framework to end a costly 110-day war that has disrupted global energy markets and destabilized the Middle East. The agreement imposes an immediate halt to military operations on all fronts and initiates a 60-day window for technical negotiations aimed at reaching a comprehensive nuclear and economic settlement.[4][5]

The document was signed remotely, with President Donald Trump affixing his signature during a G7 summit dinner at the Palace of Versailles in France, and Iranian President Masoud Pezeshkian signing in Tehran. Brokered heavily by Pakistani mediators, the MOU serves as a preliminary ceasefire rather than a finalized treaty, leaving the most contentious details regarding sanctions relief and nuclear inspections to be hammered out in upcoming talks in Switzerland.[4][5]

Under the immediate military terms of the agreement, the United States will begin lifting its naval blockade of Iranian ports, with a commitment to fully remove impediments within 30 days. In exchange, Iran has agreed to reopen the Strait of Hormuz—a critical artery for global oil supplies—to commercial shipping toll-free for the duration of the 60-day negotiation period. The text also explicitly calls for the termination of military operations in Lebanon, a clause that effectively requires Tehran to rein in Hezbollah forces.[4][5]

The economic and nuclear provisions outline a high-stakes roadmap. The MOU stipulates that international inspectors from the International Atomic Energy Agency (IAEA) will be granted access to oversee the destruction or removal of Iran's highly enriched uranium stockpile. If Tehran meets these nuclear compliance benchmarks, the U.S. and its regional partners have pledged to develop a reconstruction and economic development plan for Iran worth at least $300 billion, alongside a scheduled lifting of sanctions.[4][5]

President Trump has aggressively touted the agreement as a decisive American victory, characterizing it as an "unconditional surrender" by Tehran. Speaking to reporters, Trump emphasized the devastating toll the U.S. military campaign took on Iranian forces, claiming that 159 Iranian naval ships were destroyed and sent to the "bottom of the sea" during the conflict.[1]

Vice President JD Vance has also defended the framework, pushing back against domestic critics by arguing that the U.S. "wins either way." Vance emphasized that the immediate reopening of the Strait of Hormuz provides vital relief to the global economy, while the 60-day window places the burden of proof squarely on Iran to dismantle its nuclear capabilities before any substantial financial relief is delivered.[2]

Despite the administration's assurances, the MOU has faced intense skepticism from Republican lawmakers on Capitol Hill. Senators including Tom Cotton and Rick Scott have voiced alarm over the proposed $300 billion reconstruction fund and the prospect of unfreezing Iranian assets. Critics argue that offering massive financial incentives mirrors the flaws they saw in the 2015 Obama-era nuclear pact, warning that Tehran could use the funds to rebuild its military and fund proxy networks once the immediate crisis passes.[6]

In Tehran, the agreement has been met with a mixture of pragmatic acceptance and hostile rhetoric. Supreme Leader Ayatollah Ali Khamenei authorized the signing, but Iran's Supreme National Security Council (SNSC) quickly issued a statement declaring "complete distrust" of the United States. The SNSC warned that Iranian forces are closely monitoring the implementation of the deal and have a predetermined plan for "reciprocal action" if Washington fails to honor its commitments or attempts to alter the terms during the 60-day window.[3][7]

Regional observers note that the inclusion of Lebanon in the ceasefire terms introduces a significant layer of fragility. While the MOU dictates an end to hostilities on that front, Israeli officials have maintained that they will not withdraw their troops from Lebanese territory until their own security objectives are met. This discrepancy leaves a dangerous flashpoint unresolved, as Hezbollah and Israeli forces continue to eye each other warily despite the broader U.S.-Iran pause.[4][8]

The focus now shifts to Bürgenstock, Switzerland, where technical delegations are set to begin the arduous process of translating the 14-point framework into a binding final treaty. With both sides retaining the right to walk away at any time, the next two months will test whether the immediate economic relief of an open Strait of Hormuz can provide enough momentum to solve a deeply entrenched geopolitical standoff.[5][8]
