Rubio lands in Gulf to sell Trump's $300 billion Iran peace deal to wary allies

US Secretary of State Marco Rubio has begun a three-day trip to the Gulf, aiming to reassure allies about a preliminary agreement reached with Iran. The deal, intended to end a four-month war, includes a proposed $300 billion fund, which has raised concerns among regional partners.

Arriving in Abu Dhabi, Rubio acknowledged that allies' disquiet with the accord would be a key topic of discussion. Gulf states are particularly worried that the substantial fund could be used by Iran to rebuild its military capabilities. Furthermore, the agreement does not address Iran's ballistic missile program, a significant concern for Gulf nations that have been targeted by Iranian missiles and drones during the recent conflict.

Rubio's mission is considered delicate, as he must defend the preliminary accord, which President Donald Trump strongly supports, while also addressing the circumspect views of US regional allies. Many Gulf leaders, while pushing for peace, were reportedly surprised and disappointed by the terms of the agreement.

This diplomatic effort follows a round of talks led by Vice President JD Vance with Iranian counterparts over the weekend. Rubio's public remarks during his tour will be closely watched to gauge how the administration frames the deal, especially given past Republican criticism of Iran policy.

That most certainly will come up in these discussions.
