U.S. Secretary of State Marco Rubio said Wednesday that the United States will not take actions that undermine the security of Gulf allies [1].
The statement comes as Washington attempts to manage regional anxiety over a newly announced memorandum of understanding with Iran. Gulf nations have expressed concern that the deal could compromise their own stability, or leave them vulnerable to Iranian influence.
Rubio began a diplomatic tour of the region on Wednesday, June 24, 2026 [2]. The trip includes visits to Kuwait City to meet with the Emir, as well as stops in Abu Dhabi and Bahrain [3]. These meetings are designed to provide clarity on the specifics of the U.S. approach toward Tehran.
At the center of the diplomatic tension is a U.S.–Iran memorandum of understanding valued at $300 billion [4]. This agreement follows a four-month war involving the United States, Israel, and Iran [5]. The scale of the financial terms and the recent history of conflict have left regional partners seeking firm guarantees regarding the U.S. security umbrella.
Rubio said the U.S. will not do anything that would undermine the security of its allies in the context of its dealings with Iran [1]. The Secretary of State is tasked with selling the peace deal to wary partners who fear that a rapprochement between Washington and Tehran might come at the expense of Gulf sovereignty.
While the U.S. emphasizes the stability provided by the memorandum, the Gulf states remain focused on the practical implications of the $300 billion [4] arrangement. Rubio's tour aims to ensure that the transition from active conflict to a negotiated settlement does not create a security vacuum in the region.
“The United States will not take actions that undermine the security of Gulf allies.”
This diplomatic push indicates that the U.S. is attempting to pivot from a period of direct military conflict with Iran to a high-stakes economic and political settlement. By visiting Kuwait, the UAE, and Bahrain, the U.S. is acknowledging that the $300 billion deal cannot succeed without the tacit approval—or at least the neutrality—of the Gulf states, who view Iranian regional ambitions as an existential threat.
