An AP review found that both Washington and Tehran were making expansive claims about the Strait of Hormuz that exceeded what publicly verified evidence could establish. Military presence, commercial passage and legal authority are separate tests, making declarations of control an unreliable guide to conditions at sea.

U.S. officials said American forces were taking or restoring control of the strait. Iran asserted authority to manage traffic and potentially collect fees under its interpretation of an interim arrangement. The United States and other governments dispute Iran's legal position and cite freedom of navigation.

Commercial traffic, naval escorts and observed attacks provide more concrete evidence than official slogans. The narrow waterway carries about one-fifth of normal global oil and gas flows. Control can mean the ability to deny passage, maintain routine traffic, escort ships or impose rules; those are not identical. Coastal states have rights in territorial waters, while international navigation law constrains interference with transit.

Clear distinctions between physical control, shipping access and legal rights help readers assess escalation without amplifying wartime propaganda. Treating control as a binary prize hides the practical question facing crews: can a ship pass safely, predictably and lawfully? A navy may dominate open water yet still fail to prevent missile or drone attacks, while a coastal state may disrupt traffic without possessing uncontested legal authority.

Fact-checking wartime claims requires updating conclusions as ship movements and military operations change. Open-source evidence cannot reveal every submarine, missile battery, rule of engagement or classified naval operation. That distinction matters because a current report should not turn an unresolved point into a conclusion.

Watch independent vessel-tracking and insurer advisories for changes in actual transit. Watch whether governments publish legal memoranda or negotiated navigation terms. Those developments will show whether today's action changes durable conditions or remains an announcement whose practical effects are still incomplete.
