US and Iran Sign Preliminary Agreement to End Hostilities, Reopen Strait of Hormuz

US President Donald Trump and Iranian President Masoud Pezeshkian have formally signed a preliminary memorandum of understanding (MOU) to end their 110-day direct conflict. The landmark agreement immediately lifts the US naval blockade on the Strait of Hormuz and establishes a 60-day diplomatic window to negotiate a comprehensive settlement regarding Iran's nuclear program and Western sanctions. The signing, which took place with Trump in France and Pezeshkian signing remotely, marks a sudden halt to a war that has devastated regional infrastructure and battered the global economy.[1][2][3]

The immediate economic impact of the truce was swift. Oil prices tumbled as commercial vessels resumed transit through the critical Middle Eastern waterway. Trump celebrated the reopening on social media, declaring "Let the oil flow!" and authorizing the immediate removal of the US naval blockade. The agreement promises to restore maritime traffic to pre-war volumes within 30 days, providing immediate relief to global energy markets that had been severely constrained by the months-long standoff.[2][3]

However, the fragility of the preliminary deal is already being tested by regional allies who were excluded from the negotiations. A central pillar of the 14-point MOU explicitly calls for the "immediate and permanent termination of military operations on all fronts, including in Lebanon." This clause effectively requires Iran to rein in its proxy forces, but it also demands a halt to military campaigns against them—a condition that immediately clashed with realities on the ground.[2][3][7]

Israel, which was not a party to the US-Iran talks, has flatly rejected the Lebanon ceasefire condition. Israeli Defense Minister Israel Katz stated unequivocally that the Israel Defense Forces (IDF) will not be bound by the bilateral agreement and will not withdraw from southern Lebanon. Israeli officials maintain that their military will remain in the security zone to combat Hezbollah and protect Israel's northern residents, regardless of the diplomatic framework signed in Versailles.[5][7]

The Israeli defiance poses a direct threat to the survival of the US-Iran pact. Hours before the deal was finalized, Israel launched fresh airstrikes on the Dahiyeh district of Beirut. In response, Iranian officials, including Foreign Ministry spokesperson Esmail Baghaei, stated that ending the war in Lebanon is an "inseparable part" of the ceasefire. Tehran has placed the burden squarely on Washington, asserting that the US must ensure Israeli compliance or risk the collapse of the entire agreement.[4][7]

Beyond the battlefield, the financial mechanics of the deal are drawing intense scrutiny and political debate. The framework reportedly includes plans for a $300 billion private investment and reconstruction fund for Iran. Backed by international and Gulf businesses, the fund is designed to rebuild war-damaged infrastructure, including refineries and airports. However, access to this massive capital pool is strictly contingent on Tehran dismantling its nuclear program and submitting to a stringent international inspection regime.[6]

The prospect of a $300 billion fund has sparked immediate political backlash in the United States, with critics accusing the administration of rewarding Tehran. Vice President JD Vance defended the structure, emphasizing that the money would only unlock if Iran honors its strict nuclear obligations. Trump also pushed back against domestic critics, emphasizing that the vehicle relies entirely on private and international capital, stating that the US government is "not putting up 10 cents."[3][6]

Negotiators now face a grueling 60-day sprint to convert the preliminary MOU into a binding final agreement, with initial technical talks set to begin in Switzerland. The core challenge remains Iran's stockpile of highly enriched uranium. While the MOU freezes the status quo, the final deal must address the permanent dismantling of Iran's nuclear weapons capabilities in exchange for a scheduled termination of all Western sanctions.[1][2]

If the sides fail to reach a resolution within the 60-day window—which can be extended by mutual consent—the consequences could be severe. US officials have warned that if talks collapse, Washington is prepared to walk away and significantly tighten economic and military pressure. For now, the world watches to see if a fragile pause in hostilities can survive the deeply entrenched regional conflicts that threaten to unravel it.[2][3]
