G7 Summit Opens With US-Iran Truce and Plans to Reopen Strait of Hormuz

The 52nd G7 summit in Évian-les-Bains, France, opened Monday under the shadow of a massive geopolitical breakthrough: a tentative peace agreement between the United States and Iran. The surprise deal, designed to end months of direct military hostilities, promises to reopen the Strait of Hormuz and stabilize fractured global energy markets.[1][2]

U.S. President Donald Trump, speaking alongside French President Emmanuel Macron, announced that the 14-point Memorandum of Understanding (MoU) had been signed virtually by U.S. Vice President JD Vance and Iranian Parliament Speaker Mohammad-Bagher Ghalibaf. Trump declared that the critical shipping lane is "already partially opened" and will be fully operational by Friday, when a formal in-person signing ceremony is scheduled in Geneva.[1][5]

The economic implications of the truce are immediate and profound. Roughly 20 percent of the world's oil supply passes through the Strait of Hormuz, which had been effectively choked off by naval blockades and sea mines since the conflict escalated in late February. Global oil prices plummeted and stock markets rallied sharply as news of the impending reopening spread through the summit.[2][4]

Securing the waterway will require a massive multinational effort. Macron confirmed that France and the United Kingdom are organizing a joint naval mission to clear mines and escort commercial vessels. France is preparing to deploy the aircraft carrier Charles de Gaulle and specialized mine-clearance teams within days, while Japan is also considering dispatching Maritime Self-Defense Force minesweepers to assist the coalition.[6][8]

While European leaders expressed profound relief at the de-escalation, the mechanics of the MoU remain highly contested. The agreement establishes a 60-day ceasefire window to negotiate a comprehensive treaty covering Iran's nuclear program and regional security. However, Washington and Tehran are already issuing conflicting statements regarding the timeline for sanctions relief.[1][7]

Iranian state media and officials claim the U.S. has agreed to unfreeze between $12 billion and $24 billion in Iranian assets before the formal negotiations even begin. Conversely, U.S. officials insist that Tehran will not receive any financial relief until it demonstrates strict compliance with the deal's preliminary terms, setting the stage for early diplomatic friction.[1][2]

The most explosive element of the agreement, however, involves a third party: Israel. According to diplomatic sources, the MoU explicitly calls for the "immediate and permanent termination" of military operations on all fronts, specifically including Lebanon. Iranian negotiators reportedly insisted on this clause, tying the broader U.S.-Iran peace to a cessation of Israel's campaign against Hezbollah.[2][7]

The Israeli government, which is not a signatory to the MoU, reacted with furious defiance. Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz vehemently rejected the terms, vowing that Israeli forces will remain in "security zones" across southern Lebanon and Gaza indefinitely. Katz warned that Israel would strike Iran with "full force" if Tehran attempted to use the Lebanon clause to justify new attacks.[4][7]

The U.S.-Iran deal has triggered a rare moment of unified outrage across Israel's fractured political spectrum. Opposition leaders and government officials alike have condemned the agreement as a disaster that funnels billions of dollars to Tehran while leaving its nuclear infrastructure and ballistic missile capabilities intact, characterizing it as a profound betrayal by Washington.[4]

Despite the looming crisis with Israel, the mood among European G7 members is overwhelmingly supportive of the truce. Macron, hosting his final G7 summit, called the pact a "very important step for peace" and emphasized that Europe's primary focus is ensuring the Strait of Hormuz remains open without the imposition of illegal transit tolls.[6]

The sudden pivot to the Middle East has forced a reshuffling of the summit's broader agenda, raising concerns about the ongoing war in Ukraine. Ukrainian President Volodymyr Zelenskyy is attending the Évian-les-Bains gathering to ensure that Western military and financial support does not waver as diplomatic attention shifts toward the Gulf.[2][3]

The summit is also serving as a hub for broader geopolitical realignment. Trump is holding a series of high-stakes bilateral meetings on the sidelines of the G7, including discussions with Indian Prime Minister Narendra Modi, Egyptian President Abdel Fattah el-Sissi, and leaders from Qatar and the United Arab Emirates, aiming to solidify a new regional security architecture.[3]

The ultimate success of the Évian-les-Bains diplomatic push hinges on the coming days. Negotiators face the daunting task of translating a fragile 14-point memorandum into a binding, comprehensive treaty within 60 days, all while navigating a furious Israeli government, a skeptical U.S. Congress, and the logistical nightmare of de-mining the world's most vital energy artery.[1][7]
