ABU DHABI, June 23 (Reuters) – U.S. Secretary of State Marco Rubio faces a delicate mission this week pitching Washington’s Iran peace deal to Gulf Arab leaders who fear excessive concessions will strengthen Tehran and reshape the region’s security balance and oil flows.
Rubio will arrive in the United Arab Emirates on Tuesday, before traveling to Kuwait and Bahrain, where he will meet officials from the Gulf Cooperation Council, a grouping of monarchies that also includes Saudi Arabia, Qatar and Oman.
At issue are elements of a draft agreement that includes no limits on Iran’s ballistic missiles, a proposed $300 billion reconstruction fund and provisions that could expand Tehran’s regional influence and control over critical oil shipping lanes.
All six GCC nations are strategic U.S. allies that offered some degree of logistical support to Washington during the U.S.-Israeli war with Iran that began four months ago, and all were buffeted by Iranian airstrikes as a result.
Some of those countries are feeling privately disappointed – and surprised – by an interim deal that could open the door to U.S. normalization with Iran, a predominantly Shi’ite country that most Sunni-led GCC states consider their main adversary.
The opinions of these nations matter to U.S. policymakers.
The UAE, Saudi Arabia, Qatar, Kuwait and Bahrain all host U.S. military bases that make up the backbone of America’s security architecture in the Middle East. Should any of those countries rethink their security relationship with the U.S., even in a subtle way, it could have a significant impact on U.S. military strategy in the region.
For Rubio personally -who has maintained notable distance from the Iran talks in recent weeks, deferring almost entirely to Vice President JD Vance and other Trump aides – the trip requires a balancing act.
While America’s top diplomat needs to assuage regional allies, he must do so without appearing to criticize the U.S.-Iran memorandum of understanding. President Donald Trump, who signed the accord last week, remains firmly behind it despite criticism from some of his fellow Republicans in Congress who have accused the administration of capitulating to Tehran.
On Monday, the U.S. Treasury Department issued a broad 60-day waiver on Iranian oil sanctions, suggesting Washington is serious about moving forward with key elements of the preliminary agreement.
Andrew Peek, a former deputy assistant secretary of state for Iraq and Iran who served on Trump’s National Security Council during both his terms, argued that Rubio could reassure any nervous allies by pointing out that Trump has a history of being tough on the Islamic Republic.
“I think you can just remind them that the president has conducted extremely hawkish policies toward Iran – and if this MoU falls through, he will have no compunction about going back to striking them,” said Peek, who is now at the Atlantic Council think tank.
On Monday, Trump appeared to re-up that threat, telling reporters: “If Iran doesn’t live up to their agreement, or if they’re not behaving, I will do what I have to do.”
PEACE – BUT AT WHAT COST?
Leaders from all GCC countries hosting Rubio or present at this week’s talks at least publicly pushed for a diplomatic solution before the war kicked off in February. Most also pushed for a diplomatic off-ramp during the conflict, even as they in practice facilitated the U.S. war effort.
Still, the specific terms of the MoU privately shocked regional officials, according to analysts and diplomats.
One concern relates to ballistic missiles. Throughout the war, the Trump administration said that destroying Iran’s ballistic missile capacity was a central goal. That objective aligned with the interests of the Sunni Gulf states, all well within Iran’s ballistic range.
The MoU, however, does not mention Iranian missiles at all, and Trump himself has in recent days said that denying Tehran such weapons would be “unfair.”
The MoU also foresees a $300 billion reconstruction fund for Tehran, which regional neighbors fear could allow the Islamic Republic to build up its military capacity, while increasing support for regional proxy groups that could destabilize governments throughout the region.
Bahrain’s mainly Sunni leadership, in particular, is concerned that a well-funded Iran could foment an uprising among the island nation’s mainly Shi’ite populace, analysts say. During the Arab Spring, the nation of roughly 1.65 million was the site of massive recurring street protests.
Iran has denied any covert attempts to stoke unrest but has publicly expressed support for Bahraini Shi’ite activists in the past.
The accord, as written, also appears to concede that Iran could have a key role in controlling the Strait of Hormuz going forward, a major concern for the Gulf exporters, which rely on the strait to ship oil and gas.
More broadly, U.S. officials have begun speaking about a broader reset for Tehran, a potential transformation that most GCC states are wary of. On Saturday, Vance said the U.S. was willing to “fundamentally transform” its relationship with Tehran.
“The agreement rehabilitates Tehran’s regime as a regional power,” veteran Saudi columnist Abdulrahman Al-Rashed wrote in the Saudi English-language daily Arab News last week.
“Most of the funds Tehran will acquire in the coming weeks are likely to go primarily towards strengthening the military position, not to support living conditions or the Iranian economy.”

Executive Summary
U.S. Secretary of State Marco Rubio is visiting Gulf Arab leaders in the UAE, Kuwait, and Bahrain to discuss a draft Iran peace deal that has raised concerns among Gulf Cooperation Council (GCC) nations. The agreement, signed by President Donald Trump, includes provisions such as a $300 billion reconstruction fund for Iran and no restrictions on its ballistic missile program, which Gulf states fear could strengthen Tehran’s regional influence. The GCC countries, which host U.S. military bases, are strategic allies but feel disappointed by the deal, which they see as potentially destabilizing. Rubio must balance reassuring these allies without criticizing the administration’s agreement, which has faced criticism from some Republicans. The U.S. has already issued a waiver on Iranian oil sanctions, signaling commitment to the deal, while Trump has warned of consequences if Iran violates the agreement.
The deal’s terms, including Iran’s potential role in controlling the Strait of Hormuz and the lack of missile restrictions, have alarmed Gulf leaders, particularly Bahrain, which fears Iranian influence over its Shi’ite population. Analysts suggest Rubio may emphasize Trump’s history of tough policies toward Iran to reassure allies. However, the broader implications of the deal, including Iran’s regional rehabilitation, remain a point of contention among GCC states, who view Iran as their primary adversary.
Full Take
The narrative presents a high-stakes diplomatic balancing act, where the U.S. seeks to reassure Gulf allies while advancing a contentious Iran deal. The strongest version of this story highlights legitimate concerns: Gulf states, hosting U.S. military bases, fear the deal’s provisions—such as the $300 billion fund and lack of missile restrictions—could embolden Iran, their primary adversary. The article credits these concerns by noting historical tensions and the strategic importance of the region’s oil routes. However, it also frames the deal as a potential path to stability, with Trump’s hawkish reputation serving as a reassurance.
Patterns detected: **ARC-0024 Ambiguity** (the deal’s vague terms on missiles and regional influence leave room for divergent interpretations), **ARC-0043 Motte-and-Bailey** (the U.S. presents the deal as peace-building while downplaying concessions that alarm allies).
Root cause: The paradigm here is realpolitik—balancing short-term diplomatic gains against long-term regional stability. The unstated assumption is that Gulf allies must accept U.S. priorities, even if those priorities undermine their security. This echoes historical U.S. interventions where regional partners’ concerns were secondary to broader strategic goals.
Implications: Human agency is constrained for Gulf states, who must navigate U.S. policy shifts while managing domestic threats. The deal’s financial and military implications could destabilize the region, particularly in Bahrain, where sectarian tensions persist. Second-order consequences may include Gulf states reconsidering their security alliances, potentially shifting toward China or Russia.
Bridge questions: What would it take for Gulf states to trust this deal’s long-term benefits? How might Iran’s regional behavior change with increased funds and legitimacy? What alternatives exist for Gulf security if U.S. guarantees weaken?
Counterstrike scan: If this were an influence campaign, the playbook would involve framing the deal as inevitable while dismissing Gulf concerns as overreactions. The actual content aligns partially—emphasizing U.S. commitment while downplaying Gulf anxieties—but stops short of outright manipulation. The tone remains factual, though selective in highlighting Gulf disappointments.
