US Sets Saturday Ultimatum for Iran to Denounce Hormuz Attacks

The Trump administration has issued an explicit Saturday deadline for Iran to publicly acknowledge the unhindered opening of the Strait of Hormuz and commit to a total cessation of hostilities against commercial shipping.

U.S. officials confirmed Friday that the ultimatum was delivered to Tehran both through direct communications and regional diplomatic intermediaries.

The mandate follows a series of maritime skirmishes that Washington asserts directly violated a bilateral memorandum of understanding signed three weeks ago.

Diplomatic Brinkmanship

The escalating maritime friction has pushed the fragile security agreement to the verge of a total breakdown.

President Donald Trump declared the temporary ceasefire defunct earlier this week following repeated Iranian strikes on merchant vessels.

Diplomats from Iran and Oman are scheduled to convene in Muscat on Saturday to address the intensifying crisis.

Oman previously collaborated with U.S. and Gulf partners by establishing an alternative shipping channel near its coastline, a development that reportedly compromised Tehran’s regional leverage and triggered internal regime friction.

Internal Regime Fractures

U.S. intelligence indicates an active power struggle within the Iranian state apparatus over compliance with the memorandum of understanding.

While some Iranian negotiators reportedly expressed a desire to continue diplomacy following recent military clashes, hardline factions within the regime have actively resisted implementation.

Washington expects a formal declaration from Tehran following the conclusion of the Muscat summit.

U.S. officials have warned of severe retaliatory measures should the Iranian government refuse to issue a public, explicit guarantee regarding toll-free and unhindered transit through all channels of the strait.

Nuclear Negotiations Imperiled

The current maritime standoff raises profound administrative concerns regarding Tehran's broader reliability as a negotiating partner.

U.S. officials noted that failure to uphold basic maritime commitments complicates prospects for a far more complex nuclear accord.

While negotiators have achieved incremental progress during three weeks of indirect and direct talks, Washington is actively preparing alternative strategic options.

The administration emphasized that while time has been permitted for diplomacy, the window for a comprehensive agreement remains strictly limited.
