The Islamic Revolutionary Guard Corps Navy issued a defiant statement Thursday morning, asserting that foreign powers have “no stake” in the Strait of Hormuz and warning that any U.S. involvement in determining shipping routes through the critical waterway will trigger a “crushing response.”

In the statement, the IRGC accused Washington of “adventurism and interference” amid escalating tensions over commercial shipping in the vital oil corridor. The Guards claimed Iran has increased vessel transit through the strait over the past two weeks, but complained that recent U.S. strikes have disrupted efforts to fully reopen the route.

They further stated that transit capacity under Iranian supervision has recovered to about 50% of pre-war levels, and that passage is only being granted to vessels approved under routes designated by Iran.

The warning comes as the U.S. has conducted multiple rounds of powerful strikes on Iranian military targets in response to Tehran’s attacks on commercial vessels. While Washington emphasizes its operations are meant to protect freedom of navigation and civilian mariners, the IRGC is attempting to project strength by claiming effective control over the strait.

Iran’s top negotiator, Mohammad Baqer Qalibaf, reinforced the hardline position on X Wednesday night, writing:  

“The U.S. has yet to learn that bullying and breaking its commitments no longer come without a cost. Let me be clear: If you strike, you will be struck back. The Strait of Hormuz will be reopened only under Iranian arrangements, not through U.S. threats.”

Despite the bold rhetoric, Iran continues to face sustained U.S. military pressure, including recent strikes on Revolutionary Guard assets, while the U.S. maintains a strong naval presence with over 20 warships in the region. The situation remains tense, with both sides trading threats as the confrontation over the Strait of Hormuz continues.
