Rubio tries to reassure Gulf allies on US-Iran deal details

What Happened

United States Secretary of State Marco Rubio began a Gulf tour to reassure allies about a US-Iran memorandum of understanding (MOU) signed after over 100 days of war. The war began on February 28 when the US and Israel launched strikes that killed Iran's Supreme Leader Ali Khamenei. In retaliation, Iran attacked all six Gulf Cooperation Council (GCC) countries: the UAE was struck by approximately 2,800 missiles and drones; Kuwait's airport, commercial ports, and desalination plants were hit; and missile strikes on Qatar's Ras Laffan Industrial City caused 'significant damage'. Iran also effectively blockaded the Strait of Hormuz, costing GCC nations billions in lost oil and gas revenues. The MOU extends a ceasefire for 60 days to negotiate a permanent end, and includes resumption of traffic through the Strait, removal of a US blockade on Iranian ports, a waiver on US sanctions, and unfreezing of Iranian assets. It does not address Iran's ballistic missiles or its regional allies. During Rubio's visit, he met UAE President Sheikh Mohamed bin Zayed Al Nahyan, National Security Advisor Sheikh Tahnoun bin Zayed Al Nahyan, and Foreign Minister Sheikh Abdullah bin Zayed Al Nahyan to discuss security concerns and the Strait of Hormuz. Rubio is also scheduled to visit Kuwait and Bahrain. Separately, former President Trump posted on Truth Social that no tolls, insurance costs, or charges should be applied to ships in the Strait.

Key Actors

Why It Matters

The US-Iran war has directly targeted Gulf energy and transport infrastructure, exposing their vulnerability to Iranian missile and drone attacks and economic strangulation via the Strait of Hormuz. While the MOU offers a pathway to de-escalation and economic relief, its silence on Iran's missile capabilities and network of regional allies leaves GCC states exposed to future coercion or renewed conflict. Rubio's visit signals US commitment to regional security post-war, but Gulf allies are seeking concrete guarantees that their core security concerns will be addressed in the ongoing 60-day negotiations.

Watch For

Rubio's upcoming meetings in Kuwait and Bahrain for further security assurances. The 60-day negotiation window on Iran's nuclear program, ballistic missiles, and proxy relationships. Trump's demand that no tolls be imposed on Strait of Hormuz shipping, testing Iranian compliance. Potential Iranian reactions to the MOU's gaps and US conditions.
