Rubio Briefs G7: US-Iran War to Last Another 2-4 Weeks

Introduction: A Revised Timeline for the Conflict

U.S. Secretary of State Marco Rubio has indicated that the ongoing military conflict with Iran is expected to persist for an additional two to four weeks. This statement, made during a private meeting with G7 foreign ministers in France on Friday, marks the first time a senior U.S. official has suggested the war could extend beyond the four to six-week timeframe initially mentioned by President Donald Trump. The revised projection comes as the conflict enters its 28th day, signaling a more prolonged engagement than previously anticipated by the White House.

Details from the G7 Briefing

Inside the closed-door session, Rubio provided counterparts with an update on the U.S. strategy and diplomatic efforts. According to three sources familiar with the discussion, he explained that the U.S. is nearing a point where serious negotiations with Tehran could begin. However, communication remains indirect, conducted through intermediaries rather than direct channels. This process has been hampered by security concerns, as Iranian officials are reportedly avoiding phone communications to prevent being tracked and targeted.

Rubio also conveyed a sense of uncertainty regarding Iran's internal power structure, noting it is unclear who holds ultimate decision-making authority. He mentioned that at least two Iranian officials have shown interest in negotiations but are awaiting approval from higher leadership. Despite these diplomatic overtures, the administration continues to deploy thousands of additional troops to the region and is reportedly considering escalatory military options, which could include the use of ground forces.

Post-Conflict Strategy for the Strait of Hormuz

A key focus of the discussion was the future security of the Strait of Hormuz, a vital global oil transit chokepoint. Rubio clarified that the U.S. does not currently require assistance from G7 nations to reopen the strait. Instead, he asked allies to prepare for a post-conflict role by contributing to a maritime task force. The objective of this international coalition would be to police the waterway and ensure freedom of navigation, demonstrating to Iran that it does not control the passage. According to one source, there was unanimous agreement among the G7 ministers on this point. Rubio added that this measure is necessary because Iran intends to impose a toll on any vessels passing through the strait after the conflict.

Military and Humanitarian Developments

The conflict has seen significant military action from both sides. The U.S. military has fired more than 850 Tomahawk cruise missiles in four weeks, a pace that has reportedly raised concerns within the Pentagon about inventory levels. Concurrently, Israel has conducted strikes on weapons production facilities in Tehran and targeted Hezbollah infrastructure in Beirut, Lebanon. In response, Iran has continued to launch missiles toward Israeli cities like Jerusalem and Tel Aviv.

The humanitarian toll of the war is severe. The International Federation of Red Cross and Red Crescent Societies reported that over 1,900 people have been killed and at least 20,000 have been wounded in Iran. In response, the United Nations has formed a task force to address the impact on humanitarian aid and agricultural shipments through the Strait of Hormuz.

International Reactions and Diplomatic Efforts

The conflict has drawn varied responses from the international community. German Foreign Minister Johann Wadephul accused Russia of aiding Iran by helping to identify potential strike targets. Meanwhile, Polish Prime Minister Donald Tusk warned that a further escalation in the Middle East is possible in the coming days. The G7 foreign ministers issued a joint statement calling for an immediate halt to attacks on civilians and civilian infrastructure.

On the diplomatic front, Iran is expected to deliver a response to a U.S. peace proposal on Friday. If direct talks materialize, Vice President JD Vance is anticipated to lead the U.S. delegation, with Rubio, Steve Witkoff, and Jared Kushner also involved in the diplomatic initiatives. President Trump has postponed plans to destroy Iranian energy plants by another 10 days, extending the deadline to April 6, potentially to allow space for negotiations.

Analysis of the Extended Timeline

The extension of the war's timeline suggests that the Iranian regime has proven more resilient than U.S. planners may have initially calculated. Despite significant military pressure and strikes on command centers and missile factories, Iran's leadership maintains its grip on power. The U.S. strategy appears to follow a dual track: maintaining intense military pressure while simultaneously exploring avenues for a negotiated settlement. The emphasis on a post-war security structure for the Strait of Hormuz indicates that Washington's long-term goal is the sustained containment of Iranian influence in the region, even after active hostilities cease.

Conclusion

As the war in Iran moves into its second month, the U.S. has adjusted its public timeline, preparing allies for a longer conflict while signaling a readiness for serious negotiations. The coming weeks will be critical in determining whether the path forward leads to a diplomatic resolution or further military escalation. The international community is watching closely as Iran prepares its counter-proposal to the U.S. peace plan, a development that could shape the future of the entire Middle East.
