U.S. Secretary of State Marco Rubio arrived in Manama, Bahrain, on Wednesday to pitch a preliminary U.S.-Iran peace accord to Gulf Cooperation Council (GCC) leaders. The mission aims to address regional fears that the draft agreement, which lacks ballistic missile limits, could empower Tehran and destabilize Middle Eastern security and oil markets.
Why are Gulf allies skeptical of the U.S.-Iran preliminary accord?
The six-member GCC—comprising Saudi Arabia, Qatar, Oman, the United Arab Emirates, Kuwait, and Bahrain—views the proposed framework with significant caution. According to Reuters, these Sunni-led monarchies fear that excessive concessions to Tehran could shift the region’s security balance and threaten vital oil flows.
Specific terms within the draft agreement have heightened these concerns. The current document includes no limits on Iran’s ballistic missile program. Additionally, the accord contains provisions that could expand Tehran’s regional influence and its control over critical maritime shipping lanes.
The economic implications also weigh heavily on regional leaders. The draft suggests a $300 billion reconstruction fund for Iran. While a Memorandum of Understanding (MoU) indicates that regional countries might be partially responsible for these costs, Rubio told reporters in Kuwait that he is not asking allies to contribute to any such fund during this trip.
What are the conflicting claims regarding nuclear inspections?
A major point of contention involves the level of oversight Iran will allow. U.S. President Donald Trump stated on Tuesday that Iran has agreed to nuclear inspections into “infinity.” However, Tehran has countered this claim, stating it made no such concession during negotiations.

This discrepancy follows a first round of negotiations held in Switzerland on Monday. Beyond inspections, the two nations have offered contradictory accounts regarding:
- Financial incentives provided to Iran.
- Control and access to the Strait of Hormuz.
- The impact of Israel’s ongoing conflict in Lebanon.
| Issue | U.S. Position (Trump Admin) | Tehran Position |
|---|---|---|
| Nuclear Inspections | Agreed to “infinity” | No such concession made |
| Financial Incentives | Conflicting accounts provided | Conflicting accounts provided |
How could the deal impact regional security and stability?
The potential for U.S. normalization with Iran creates internal pressure for several Gulf states. For Bahrain, the stakes involve domestic stability. The country is ruled by a Sunni monarchy but maintains a Shi’ite majority. Local officials expressed concern to Reuters that a financially liberated Tehran could encourage unrest among Bahrain’s Shi’ite population.
The GCC nations acted as strategic U.S. allies during recent conflicts, providing logistical support to Washington. Many of these states were also directly affected by Iranian airstrikes. Consequently, any shift in the U.S. security architecture could prompt these allies to rethink their long-term military relationships with the United States.
What happens next for the U.S.-Iran framework?
Rubio’s meetings in Manama on Thursday represent the final leg of a three-day tour through the UAE, Kuwait, and Bahrain. His goal is to convince skeptical allies that the Trump administration’s preliminary accord will not undermine their security. The success of this mission will likely determine how much support the GCC provides for the implementation of the framework agreement.
