Strait of Hormuz conflict: US rejects Iran's reopening deal

Why did the US reject the Iranian proposal for the Strait of Hormuz?

President Donald Trump rejected the proposal on Saturday, labeling the Iranian offer as an attempt to secure a deal because Tehran is "losing so badly." Speaking to reporters at the White House, the US President dismissed the terms of the negotiation, stating that the proposal was not acceptable to the United States. Trump emphasized that the US already possesses "total control" over the strait, despite the significant economic consequences of the current closure.

The rejection has direct implications for global energy markets. The closure of the waterway has contributed to massive rises in global oil prices and steep increases in fuel costs for consumers worldwide. By refusing the deal, the Trump administration is maintaining a hardline stance against Tehran's attempts to normalize shipping through the corridor under current conditions.

The US position on Iranian maritime offers

The US administration's stance is supported by high-ranking officials, including US Ambassador to Nato Matthew Whitaker. In a statement to Fox News, Whitaker criticized the Iranian proposal as a collection of "half measures" and "illusory deals" intended to improve Tehran's international standing. Whitaker reinforced the President's authority to dismiss such offers, suggesting they lack the substance required for a genuine resolution to the maritime blockade.

How is Iran responding to the diplomatic impasse?

Iranian Foreign Minister Abbas Araghchi stated that only a "negotiated solution" can bring an end to the ongoing conflict between the US and Iran. In a Telegram post, Araghchi acknowledged the rejection by President Trump but noted that Tehran is awaiting a "definitive" official response from the United States. He expressed skepticism regarding the consistency of the US position, noting that the President has issued contradictory statements in the past.

Araghchi maintained that the conditions proposed by Iran to reopen the strait are identical to those outlined in a memorandum of understanding (MOU) signed between the two nations in June. This MOU was intended to provide a framework for de-escalation, but its viability has been called into question by Iranian leadership following the resumption of US military actions.

Internal Iranian perspectives and leadership stability

President Masoud Pezeshkian has highlighted the deep-seated distrust caused by the war as a primary obstacle to successful dialogue. Speaking to CBS, Pezeshkian suggested that while Iran is open to implementing the June MOU in stages, the US must demonstrate that it has no intention of attempting to overthrow the Iranian government. He pointed out that the US "tore up" the existing agreement when it resumed its bombing campaign, complicating any path toward reconciliation.

Questions also remain regarding the health of Iran's new Supreme Leader, Mojtaba Khamenei. Following reports that he sustained serious injuries to his face and legs during a US strike in February, his public appearance has been non-existent. However, President Pezeshkian has attempted to downplay these concerns, stating he has met the Supreme Leader twice and that there are no ongoing health challenges preventing him from conducting lengthy official talks.

What is the impact of 'Operation Economic Outcast' on Iran?

The Trump administration is utilizing a strategy known as "Operation Economic Outcast" to exert maximum economic pressure on Tehran. This initiative aims to leverage a blockade to force Iran to cease its attacks on vessels navigating the Strait of Hormuz. Treasury Secretary Scott Bessent indicated that these sanctions are already having a measurable effect on the Iranian economy.

According to Bessent, the economic pressure has led to several regional shifts, including:

The halting of flights from various Iranian airlines by Turkey and Oman.
The cessation of flight services by the United Arab Emirates.
The suspension of financial transactions with Iranian entities by certain banks in both the UAE and Turkey.

Despite these measures, the effectiveness of the blockade remains a subject of debate among economists. A significant factor in this uncertainty is the role of China, which remains Iran's largest oil purchaser. Historically, China has ignored US-led sanctions to continue its trade with Tehran, potentially providing a financial lifeline that mitigates the impact of 'Operation Economic Outcast'.

What role are regional mediators playing in the crisis?

Oman continues to serve as a primary mediator in the efforts to resolve the tension between the US and Iran. During the UN General Debate, Omani Foreign Minister Sayyid Badr bin Hamad bin Hamood Albusaidi called for all involved parties to engage in open dialogue. The Omani government is actively seeking cooperation from all sides to ensure the safety of navigation in the strategic waterway.

The mediation efforts are occurring against a backdrop of high-level diplomatic activity in New York. While Iran raised the issues of reopening the strait and ending hostilities on the sidelines of the UN General Assembly, the lack of a consensus between the two superpowers has left the mediation efforts in a state of uncertainty. The success of Oman's intervention likely depends on whether the US moves toward a definitive diplomatic stance or continues its policy of economic and military pressure.
