Is the Iran war weakening the US' superpower status?

What Happened

On June 16, 2026, US President Donald Trump announced a deal with Iran to end a conflict launched jointly with Israel over three months prior. Trump said he had 'fully authorize[d] the toll-free reopening of the Strait of Hormuz,' with a memorandum of understanding (MoU) to be signed in Geneva later that week. Unconfirmed reports in pro-regime Iranian media, specifically Fars news agency, claimed that 'Iranian-Omani sovereignty over the Strait of Hormuz' had been added to negotiations and that the US had 'accepted' that fees would be paid to Iran. Vice President JD Vance told CNBC that Washington's 'expectation is that the strait is going to be opened in a toll-free way for the long term' but acknowledged technical negotiations are ongoing. The conflict saw US and Israeli airstrikes degrade Iran's conventional navy and leadership, yet Iran used drones, mines, and small boats to effectively block the strait, extracting concessions.

Key Actors

Why It Matters

The war and its outcome undermine the US role as a guarantor of freedom of navigation and global trade. Iran's ability to shut the Strait of Hormuz through asymmetric means—despite losing its conventional navy—demonstrates that regional actors can hold global energy flows hostage. A deal that grants Iran fees or partial control would set a precedent, raising doubts among Gulf allies about US security commitments and potentially inviting future coercion.

Watch For

The signing of the US-Iran MoU in Geneva later this week and the release of its text, which will clarify whether Iran gains toll-collection rights or sovereignty over the strait. Subsequent technical negotiations on the strait's status. The start of nuclear talks that may be linked to the deal. Reactions from Gulf states, Israel, and other major powers, and any indication of renewed Iranian threats to close the strait.
