The Strait of Hormuz is not a national checkpoint. It is one of the world's most protected international waterways under maritime law.

Connecting the Arabian Gulf to the Gulf of Oman, the narrow corridor carries nearly one-fifth of globally traded oil.

Because of that importance, the United Nations Convention on the Law of the Sea (UNCLOS) guarantees uninterrupted transit passage for civilian shipping.

That legal standard bars any coastal state from halting, taxing, licensing or selectively approving vessels using the strait.

Yet the Iranian regime has repeatedly threatened closure, demanded coordination from merchant ships and floated transit restrictions.

Those actions directly challenge the long-settled international principle that no single country controls an international strait.

The regime signed UNCLOS, even without ratifying it, and remains bound by core customary navigation norms recognized globally.

Legal experts have long noted that transit passage through Hormuz cannot be suspended at the discretion of bordering states.

That means any demand for prior authorization, vessel vetting or passage fees falls outside accepted international law.

Recent reports show commercial shipping has already been disrupted by coercive monitoring, attacks and Iranian-imposed procedures.

One cargo vessel was struck this week while transiting Hormuz, underscoring how quickly unlawful interference becomes a global security crisis.

US Secretary of State Marco Rubio has stressed that the issue is not political interpretation but black-letter law.

He noted that international waterways cannot be mined, weaponized or converted into coercive toll lanes by any coastal power.

That warning carries weight because acquiescence in Hormuz would shatter the broader maritime order protecting commerce worldwide.

If one state can unilaterally dictate who passes, under what terms and at what price, every strategic chokepoint becomes vulnerable.

Insurance costs rise, energy prices surge and global supply chains bend under the pressure of manufactured instability.

The Iranian regime's ongoing conduct therefore represents more than regional brinkmanship; it is a test of international resolve.

The world must reject any normalization of unlawful control in Hormuz before temporary harassment becomes permanent precedent.
