Blockades and fees: Why are the US’s actions in Hormuz legal while Iran’s are not? – interview

According to Adv. Yoav Harris, the legality of blockades in the Strait of Hormuz hinges on adherence to international law, specifically the San Remo Manual and UNCLOS. While the US's blockade could be legal if it meets criteria like impartiality, effectiveness, and allowing humanitarian aid, Iran's actions are deemed illegal. Iran's blockade, announced March 4, 2026, is problematic because it failed to distinguish between enemy and neutral vessels, targeting all ships allegedly not coordinating with the regime. Harris stated, "If we look into what Iran did here, it was simply firing at vessels going through the Strait of Hormuz. It has no basis in international law. It is very close to what is defined as piracy." Additionally, Iran's intention to charge compulsory fees for transit and security services, even for routes closer to Oman, violates international law, as services cannot be forced upon vessels.
