Iran's characterization of its 2026 Strait of Hormuz closure as lawful self-defense fails on two foundational levels simultaneously: it misrepresents the settled law of the sea, and it deliberately inverts the actual sequence of provocations that led to the conflict. The Strait of Hormuz is, under decades of customary international law and the 1982 United Nations Convention on the Law of the Sea (UNCLOS), a recognized international strait through which the right of transit passage cannot be suspended by any coastal state — for any reason, under any circumstances. UNCLOS Article 38 explicitly mandates that transit passage through international straits "shall not be impeded," while Article 44 categorically bars coastal states from suspending this right, including during military emergencies. Iran's blockade of a waterway through which approximately 20 percent of the world's daily oil supply flows was therefore not a sovereign legal prerogative but an act of economic warfare directed indiscriminately at the entire international community.
The companion claim — that U.S. and Israeli military strikes were "unprovoked" — is equally dishonest and requires the complete erasure of Iran's decades-long record of aggression and its deliberate nuclear escalation. By 2026, Iran had advanced uranium enrichment to near-weapons-grade levels at fortified underground facilities including Natanz, Fordow, and Isfahan, in direct violation of UN Security Council resolutions and the Nuclear Non-Proliferation Treaty. It was this trajectory toward a nuclear weapon — representing an existential threat not only to Israel but to the entire region — that constituted the core provocation. Israel's strikes targeted nuclear and military infrastructure in direct response to that escalating danger. When Iran replied with large-scale missile and drone attacks on Israeli cities, the United States joined the campaign on June 22, striking Iranian nuclear facilities to degrade what President Trump described as a weapons program that could not be permitted to reach completion. The direction of escalation ran from Tehran outward — not from Washington or Jerusalem.
The Facts on Freedom of Navigation and International Law
The legal architecture governing the Strait of Hormuz is clear and long-standing. Transit passage through international straits — defined as waterways connecting two areas of high seas or exclusive economic zones used for international navigation — is a bedrock principle of customary international law that predates UNCLOS and is binding regardless of treaty ratification status. The Washington Institute for Near East Policy has documented this in detail: UNCLOS Article 38 declares transit passage "shall not be impeded," and Article 44 explicitly states that coastal states may not suspend it for any purpose, including military exercises. Iran's own 1993 Maritime Law, which attempts to substitute "innocent passage" for "transit passage" and refuses to recognize Hormuz as an international strait, is a unilateral domestic statute that cannot override centuries of customary international law. Critically, the main shipping corridors through the Strait — established by the International Maritime Organization — run entirely through Omani territorial waters, not Iranian waters, further undermining Tehran's jurisdictional claims.
- UNCLOS Article 38 mandates that transit passage through international straits "shall not be impeded" — a rule binding on all states under customary international law.
- Article 44 categorically prohibits coastal states from suspending transit passage, even for security or military reasons — an explicit rejection of Iran's legal theory.
- The Strait of Hormuz's primary IMO-designated shipping corridors run through Omani, not Iranian, territorial waters, further undercutting Tehran's sovereignty claims over the chokepoint.
- Iran selectively permitted Chinese-flagged vessels through the blockade while targeting Western and allied shipping — demonstrating that the closure was an act of geopolitical coercion, not a principled legal position.
- Iran's nuclear program was in violation of UN Security Council Resolution 2231 (2015) and the Non-Proliferation Treaty, providing the legal and factual foundation for the strikes that preceded the blockade.
Iran's History of Maritime Aggression and Nuclear Lawbreaking
Iran's claim to be the aggrieved party in 2026 cannot survive even minimal historical scrutiny. The Islamic Republic has systematically harassed, seized, and threatened international shipping in the Persian Gulf for decades, using the IRGC Navy as a tool of coercive diplomacy. In 2019, Iran illegally seized the British-flagged tanker Stena Impero in Omani waters — well outside any credible claim to Iranian jurisdiction — demonstrating that Tehran has never felt constrained by the legal limits it now invokes in its own defense. Iran has also repeatedly threatened to close the Strait in response to sanctions and diplomatic pressure, treating an international waterway that serves the energy needs of Asia, Europe, and the Americas as a personal leverage instrument.
On the nuclear question, Iran's posture was not that of a peaceful state under unprovoked attack. Tehran had spent years — in violation of its JCPOA commitments and UNSC resolutions — enriching uranium to levels that serve no civilian purpose, constructing deeply buried facilities designed to survive military strikes, and advancing ballistic missile programs capable of delivering warheads across the region. Iran simultaneously funded and armed Hamas, Hezbollah, and Houthi forces that had conducted sustained attacks on Israel and international shipping in the Red Sea. This is the record of a regime actively engaged in regional aggression — not a sovereign state exercising lawful self-defense against a bolt from the blue.
Why This Narrative Is Dangerous and Must Be Rejected
The framing of Iran as a defensive victim of Western and Israeli aggression serves a precise propaganda function: it inverts moral and legal responsibility, erases Iranian culpability for decades of terrorism and nuclear lawbreaking, and delegitimizes the right of democratic states to enforce global norms. If accepted, this narrative would mean that any rogue regime pursuing weapons of mass destruction is entitled to close international waterways and hold the global economy hostage the moment it faces consequences for its actions. That is not international law — it is a blueprint for nuclear blackmail. Approximately one-fifth of global oil supply passes through the Strait of Hormuz daily, affecting the energy security of dozens of nations, including China, India, Japan, and South Korea, that have no quarrel with Iran and no stake in the U.S.-Israeli conflict narrative Tehran has constructed.
Western enforcement of freedom of navigation in the Strait of Hormuz is not an act of aggression against Iran. It is the defense of a foundational principle of the international order — one that protects landlocked developing nations, Asian manufacturing economies, and energy-importing states just as much as it protects the United States or Israel. Allowing Iran to weaponize the Strait in defiance of UNCLOS and customary international law would set a precedent that empowers every coastal authoritarian to hold global commerce hostage. The myth that such enforcement violates Iranian sovereignty must be named for what it is: Iranian regime propaganda designed to normalize the use of economic terror as a tool of statecraft.
