| The author asserts there is no legal way to force a toll as: "Under the United Nations Convention on the Law of the Sea, the Strait of Hormuz is an international strait where all ships enjoy a right of transit passage that coastal states cannot suspend." Except neither Iran nor the USA has ratified the Law of the Sea, which makes this weaker than the author presents. If the US wants to rely on "customary law binds non-ratifiers" to hold Iran to transit passage, that same logic applies to the US's own non-ratification. You can't invoke UNCLOS as binding custom on Iran while treating US non-ratification as irrelevant. The author asserts there is no practical way to force a toll as: "The scale of the waterway makes it far more difficult to physically stop, inspect and control vessels that refuse to pay a toll. Imposing a toll is one thing; enforcing it against unwilling ships is another entirely." Except they don't. The Iranians don't need to inspect every ship. In fact, spot-checking is plenty, since they just need to threaten to destroy ships. International shipping insurers will force compliance on Iran's behalf as underwriters price the risk and shipowners route around it voluntarily. I'm not a fan of the situation and certainly don't condone Iranian support for terror organizations, but let's not pretend they lack a legal and enforceable way to disrupt shipping in the Strait of Hormuz. In fact, they've established/proposed a route through the Strait between the Qeshm and Larak islands that gives them even greater control over traffic. |
Here, you are assuming that those threatened will do nothing. Why? Even when India, for example, had some issues with piracy, they started sending their warships to patrol the route. That's the point the author makes - it will be difficult because if Iran is challenged, it needs to have the political will and military power to fight those who challenge it. You can't fight the whole world.
