Iranian Foreign Minister Abbas Araghchi said the U.S. Navy and other foreign powers must leave the Strait of Hormuz or face action on June 12, 2026.

This escalation threatens the stability of one of the world's most critical maritime chokepoints. The warning comes as a two-month-old cease-fire [1] remains precarious following consecutive nights of military clashes.

Araghchi said Iran holds "sole responsibility" for the Strait of Hormuz [2]. He established a 30-day timeline [3] to restore the strait to its pre-war operating capacity. The minister said foreign powers must stay out of the area to prevent further interference.

The tension follows a fragile memorandum of understanding between the U.S. and Iran [2]. While some reports suggest the agreement includes ending the naval blockade, Araghchi's rhetoric emphasizes unilateral Iranian control over the waters between Iran and Oman [4].

U.S. leadership has previously signaled a willingness to engage. Donald Trump said, "We must respond," on June 9 [5], following reports of military friction in the region.

The Strait of Hormuz is a strategic gateway for global energy shipments. Any sustained conflict or blockade in these waters could disrupt international oil markets and trigger wider geopolitical instability, a risk heightened by the current military volatility [4].

"Iran holds 'sole responsibility' for the Strait of Hormuz."

The contradiction between the Islamabad Memorandum of Understanding and Araghchi's demands suggests a breakdown in the diplomatic framework intended to manage the Strait. By asserting sole responsibility and setting a rigid 30-day deadline, Iran is testing the resolve of the U.S. Navy and challenging the shared management of the waterway, potentially pivoting from a cease-fire toward active maritime confrontation.
