President Donald Trump stated that Iran has "agreed to that 100%" not to possess a nuclear weapon and that the Strait of Hormuz saw a record 19 million barrels of oil transit on June 23 [4]. The same day, Secretary of State Marco Rubio told Gulf Cooperation Council foreign ministers in Bahrain and Kuwait that any US-Iran deal would protect their security, while rejecting any arrangement allowing Iran to charge fees for strait passage [2][3]. The two developments — Trump's public claims about Iranian commitments and Rubio's reassurance tour — follow a 60-day negotiation framework agreed in earlier Swiss-mediated talks between Washington and Tehran.
Trump told reporters that Iran had accepted nuclear inspections "into infinity" and that the United States would channel some Iranian funds — if and when released — into purchases of American wheat, soybeans, and corn for Iran [4][2][10]. A White House official separately stated that under the potential agreement, Iran would be obligated to destroy its enriched uranium stockpile, dismantle parts of its nuclear program, and never seek a nuclear weapon [15]. An unnamed US official told the Associated Press that no frozen funds have been released and none will be until Tehran meets the interim agreement's requirements [10]. Treasury Secretary Scott Bessent said "a very large percentage of it will go to buy US foodstuffs and medicines" [10].
Iranian officials offered a different account of what has been agreed. Iran's Deputy Foreign Minister for Legal and International Affairs said the 60-day talks focus solely on the nuclear issue, sanctions termination, reconstruction, and a monitoring mechanism [11]. A senior Iranian diplomat and Director General of the Parliamentary Department of the Ministry of Foreign Affairs stated that the initial memorandum contains no obligations regarding high-enriched uranium or a 20-year suspension of enrichment, and that all nuclear matters are deferred to the 60-day negotiation period [12]. The gap between Washington's description of binding Iranian commitments and Tehran's insistence that nuclear specifics remain unresolved is unresolved in the available record [4][12].
The International Atomic Energy Agency occupies a central position in this dispute. IAEA Director General Rafael Grossi announced that inspectors would visit Iran's enrichment sites under the new interim agreement [13]. However, Grossi had previously warned that the agency has lost continuity of knowledge regarding Iran's enriched uranium stockpile, particularly at a facility in Isfahan where near-weapons-grade uranium is stored, and may declare Iran in non-compliance with the Nuclear Non-Proliferation Treaty if access is not restored [14][21]. At the IAEA General Conference, Grossi called for early resumption of inspections, linking the verification gap to broader security risks [22].
Rubio's Gulf tour addressed a separate set of anxieties. In Kuwait, he stated: "We're not going to do anything that undermines the security of our allies, our longstanding allies in the region" [8]. In Bahrain, he warned that allowing Iran to impose fees on shipping through the Strait of Hormuz would cause "total chaos" and said the US wants a deal but "not at any price" [3]. GCC foreign ministers issued a joint statement that "lasting regional peace and security requires addressing the full spectrum of Iran's threats, including its ballistic missiles, drones and support of proxies" [3]. Bahrain's Foreign Minister Abdullatif bin Rashid Al Zayani welcomed Oman's announcement of a corridor for safe vessel passage through the strait [2], while Oman's top diplomat Badr Albusaidi said the plans "do not entail the imposition of any transit fees" [3].
Gulf states are also pursuing diplomatic channels independent of Washington. An unnamed Gulf diplomat confirmed that countries in the region are preparing a direct dialogue with Iran, likely to be hosted in Saudi Arabia, with invitations extended to Iraq, Jordan, and others [5]. RFI reported that this initiative reflects Gulf states' desire for autonomous diplomatic agency rather than reliance on US-mediated negotiations [5].
Israel's position stands apart from both the US framing and the Gulf approach. Prime Minister Benjamin Netanyahu stated that any US-Iran agreement must dismantle Iran's nuclear infrastructure, not merely pause enrichment [19]. Israeli security analysts and former officials described the emerging deal as failing to meet Israel's key military objectives [20].
Domestic US politics added another layer of friction. Senator Bill Cassidy engaged in a shouting match with Trump during a closed-door Republican lunch, telling reporters afterward: "The American people need to know more than we are being told" [8]. Senator John Kennedy described Trump during the encounter as "mad as a murder hornet" [1]. The confrontation preceded a late-night Senate vote to block a war powers resolution on Iran; Senators Rand Paul and Cassidy reversed their earlier votes after Trump's lobbying [1]. Trump subsequently posted on Truth Social: "This vote puts Iran on notice" [8]. The Guardian reported the clash revealed divisions within the Republican caucus over the administration's Iran policy [18].
Maritime security in the strait remains precarious despite the diplomatic activity. International Maritime Organization Secretary General Arsenio Dominguez announced a temporary pause in efforts to evacuate 600 ships and their crews trapped by the conflict, citing the need to "reconfirm that the necessary safety guarantees continue to be in place" after an attack on a cargo ship [3]. An Axios leak of the memorandum of understanding, as reported by Ahram Gate, detailed provisions for Hormuz reopening without fees, sanctions relief, and a 60-day ceasefire [17].
A policy analysis from the Quincy Institute's Responsible Statecraft argued that durable stability requires going beyond bilateral US-Iran negotiations to build a regional security architecture, including a non-aggression pact between Israel and Iran, a UN-supervised surcharge mechanism as an alternative to Iranian tolls, and a standing negotiating table led by middle powers such as Turkey, Saudi Arabia, and Pakistan [6].
The 60-day negotiation window established in the Swiss-mediated framework continues, with IAEA inspector visits to Iranian enrichment sites expected and Rubio's Gulf tour ongoing [13][2]. The administration has requested $70 billion in congressional funding for the war effort [8], and the Senate's war powers vote remains a point of contention between the White House and members of its own party [1][18].
