US and Iran Reach Deal to End War and Reopen Strait of Hormuz, but Israel Vows to Maintain 'Security Zones'

The United States and Iran have reached a preliminary agreement to end a devastating months-long war, signaling a potential close to a conflict that has severely disrupted global energy markets. The memorandum of understanding, mediated by Pakistan, outlines an immediate and permanent termination of military operations across all fronts. The diplomatic breakthrough sets the stage for an official signing ceremony scheduled for Friday in Switzerland, offering a fragile off-ramp from a war that began with US and Israeli strikes in late February.[4][6][7]

At the center of the agreement is the reopening of the Strait of Hormuz, a vital maritime chokepoint that Iran had blockaded, alongside the reciprocal lifting of a US naval blockade on Iranian ports. President Donald Trump heralded the deal's completion, declaring that he had authorized the immediate removal of the US blockade and that the strait would be "permanently toll-free." "Ships of the World, start your engines. Let the oil flow," Trump announced, claiming that vessels loaded with crude were already beginning to move.[6][7]

The prospect of unfreezing a waterway that handles roughly 20 percent of the world's oil consumption sent an immediate shockwave through global markets. Crude oil prices tumbled nearly 5 percent toward $80 a barrel, retreating from the $110 highs seen at the war's onset. Equities rallied in tandem, with the benchmark S&P 500 climbing 1.7 percent and the tech-heavy Nasdaq jumping 3.1 percent as investors bet on an end to the energy chaos.[2][7]

However, the immediate relief on Wall Street will not translate to instant savings for consumers at the pump. Energy analysts warn that US fuel prices will take months to fully normalize. Producers require significant time to ramp up output, and persistent port bottlenecks combined with heightened summer demand will keep prices elevated even as crude oil begins to flow more freely through the Gulf.[5]

The shipping industry is also treating the political declarations with profound caution. While maritime organizations welcomed the diplomatic progress, a Joint Maritime Information Center advisory warned that the US blockade technically remains in effect until the Friday signing. The advisory instructed mariners not to attempt crossing the strait until explicit direction is given, noting that the maritime threat level remains "severe" and that enforcement actions—including vessel boardings—are still active.[10]

In Washington, the diplomatic victory lap was quickly complicated by fierce domestic debate over the financial concessions embedded in the framework. Rumors circulated that the agreement included a staggering $300 billion reconstruction fund for Iran, prompting outrage from critics who accused the administration of using American taxpayer money to bankroll a hostile nation. Deal skeptics argued that the financial package, alongside the unfreezing of billions in Iranian assets, effectively rewarded Tehran and left it stronger than before the conflict.[1][8]

Vice President JD Vance forcefully pushed back against the narrative, clarifying the mechanics of the reconstruction package. Vance confirmed that while the $300 billion figure is real, not a single dollar will come from US taxpayers. Instead, the funds will be provided by Gulf Cooperation Council states—including Qatar, Saudi Arabia, and the United Arab Emirates—as conditional investments tied to Iran's strict adherence to the agreement. Vance emphasized that the deal requires a rigorous inspections regime and that the Gulf-funded capital is entirely dependent on Tehran's performance.[1][8]

Yet, the most severe threat to the US-Iran pact comes not from domestic politics, but from America's closest Middle Eastern ally. The memorandum of understanding reportedly includes provisions for ending military operations in Lebanon, where Israel has been engaged in a fierce ground war against Hezbollah. But Israeli leadership immediately and publicly rejected any expectation that they would withdraw their forces to accommodate the Washington-Tehran framework.[3][6]

In a defiant press conference, Israeli Prime Minister Benjamin Netanyahu stated that the IDF will maintain its presence in southern Lebanon indefinitely. "We have established strengthened security zones around Israel. We did this in Gaza, Lebanon and Syria, and we will remain in these security zones as long as necessary to protect our country," Netanyahu declared. He claimed that while Iran had demanded an Israeli withdrawal during the negotiations, Israel successfully resisted the pressure, though he admitted he had not yet seen the precise details of the US-Iran memorandum.[3][9]

Israeli Defense Minister Israel Katz reinforced the hardline stance, stating that the security zones will be cleared of local residents and that all terror infrastructure will be destroyed. Katz warned that holding the buffer zones is among the military's greatest achievements and that Israel will not compromise its security interests regardless of international pressure. "If Iran attacks Israel because of events in Lebanon, we will strike it with full force," Katz added, underscoring the explosive potential for the ceasefire to collapse.[9]

The stark disconnect between the US-brokered peace framework and Israel's operational reality leaves the Friday signing ceremony shrouded in uncertainty. Iranian officials have already struck a cautious tone, citing a history of broken commitments, while Hezbollah has insisted there can be no return to the pre-war status quo. As diplomats race toward Geneva, the world watches to see if a signature can truly untangle a multi-front war, or if the conflicting red lines in Lebanon will ignite the region once again.[4][6][7]
