The U.S. and Iran have moved into the formal implementation phase of an interim understanding aimed at de-escalating regional conflict. U.S. Central Command (CENTCOM) confirmed the immediate lifting of naval blockades on Iranian ports, though Defense Secretary Pete Hegseth emphasized that military forces remain positioned to resume operations if Tehran fails to meet its obligations. The White House has formally transmitted the agreement text to Congress, initiating a 60-day window for technical nuclear negotiations scheduled to take place in Switzerland with mediation support from Qatar and Pakistan. While the agreement provides for 60 days of fee-free passage through the Strait of Hormuz, significant friction persists regarding the long-term status of the waterway. Iranian chief negotiator Mohammad Baqer Ghalibaf signaled Tehran’s intent to begin charging transit fees once the initial period concludes. Additionally, the U.S. administration clarified that sanctions relief will be phased and tied to a timetable established in a final deal, rather than being granted immediately. Domestically, the Trump administration face political pressure as Republican critics argue the framework is overly favorable to Tehran. Vice President JD Vance has defended the move as a "win-win" security arrangement. The framework also encompasses a cessation of hostilities across regional proxy theaters, including Lebanon, though experts note that reconstruction investment from Gulf states may remain limited due to years of regional tension.
