UNITED STATES PERSPECTIVE

Washington, June 23, 2026. Eighteen hours of nearly continuous negotiations at the Burgenstock resort on the shores of Lake Lucerne: Vice President JD Vance departed Switzerland on Monday morning asserting he had 'laid very good foundations for a successful final agreement.' The carefully calibrated phrase conveys both what has been accomplished and what remains undone. 'We have laid the foundation. We have not yet built the house,' Vance acknowledged during a press briefing before his departure.

The two delegations—on the American side, Vance, Steve Witkoff, and Jared Kushner; on the Iranian side, Mohammad Bagher Qalibaf and Foreign Minister Abbas Araghchi—produced a joint communique from Qatari and Pakistani mediators praising 'encouraging progress' in 'a positive and constructive atmosphere.' Concretely, the parties agreed on a 60-day roadmap toward a final nuclear accord, the creation of a 'High Level Committee' for political oversight, and working groups on nuclear matters, sanctions, and dispute resolution.

On the economic front, Treasury Secretary Scott Bessent announced Monday the issuance of a temporary general license for 60 days authorizing the production, delivery, and sale of Iranian oil. Araghchi specified on the Iranian side that Tehran had secured waivers for its petroleum and petrochemical exports, the lifting of port blockades, and the unfreezing of some frozen assets. The question of blocked funds remains, however, a source of friction: Alex Vatanka, a researcher at the Middle East Institute, warned that the frozen assets dossier would constitute 'one of the first major implementation disputes in the coming weeks.'

The session nearly collapsed several times. Tehran announced Saturday it had closed the Strait of Hormuz in response to Israeli strikes in Lebanon—a claim that U.S. Central Command (CENTCOM) immediately denied, asserting the strait had never stopped functioning. Trump, from the United States, escalated with repeated threats on Truth Social, suggesting the possibility of striking Iran 'even harder' and seizing the strait. The Iranian delegation briefly walked away from the negotiating table after these messages were published. 'When you engage in trash talk, you cannot expect the President of the United States not to respond,' Vance countered, while defending the talks' continuity.

Among the results deemed most significant in Washington: Tehran's agreement to the return of IAEA inspectors, which Vance called a 'major milestone' and 'first step toward permanent denuclearization.' A deconfliction mechanism among the United States, Iran, and Lebanon was also established to prevent any regional escalation. Yet U.S. intelligence agencies remain skeptical: according to Axios, several officials do not believe Iran is prepared to make sufficient nuclear concessions to finalize an agreement within the prescribed timeframe.
