Rite of Passage

The MAGAnauts, and many of the others, keep mewling that the Strait of Hormuz is some kind of international waterway, and thus can't be deemed within the territorial waters of Iran and Oman. To be clear: even the olde time 12 mile limit means that Oman and Iran have an overlapping claim to the waters of the Strait. That is not in dispute, no matter what Bone Spur Samurai^© and his minions say.

But... there is an international treaty, known by its acronym UNCLOS

This is because Iran is not a party to the 1982 United Nations Convention on the Law of the Sea (UNCLOS).

And, as you'd likely guess, neither is the USofA

The USA has long been one of the most ardent champions of the freedom of navigation, despite not being a party to UNCLOS.

Neither country ever ratified the treaty.
