What Happened
- Ali Larijani, Iran's Supreme National Security Council Secretary and one of its most influential powerbrokers, issued a pointed warning: the Strait of Hormuz would become either "a Strait of peace and prosperity for all" or "a Strait of defeat and suffering for warmongers."
- The statement came in direct response to a threat from US President Donald Trump, who warned Iran would be struck "twenty times harder" if it continued blocking oil through the strait.
- Larijani's statement was posted on X (formerly Twitter), in which he called Trump's threats "hollow" and warned that more powerful forces than Trump's White House had previously failed to eliminate the Iranian state.
- Iran's Islamic Revolutionary Guard Corps (IRGC) issued a parallel statement asserting that Iran was "fully prepared for a prolonged war."
- The standoff represents the highest-stakes confrontation over the Strait of Hormuz since the Iran-Iraq War tanker war of the 1980s.

The Strait of Hormuz — Strategic Geography and International Law
The Strait of Hormuz is an international strait under the United Nations Convention on the Law of the Sea (UNCLOS), specifically subject to the right of transit passage (Part III, Section 2, Articles 37-44 of UNCLOS). Unlike innocent passage (applicable in territorial seas), transit passage cannot be suspended by the coastal state for any reason, and submarines may transit submerged.
- UNCLOS Article 38: All ships and aircraft enjoy the right of transit passage through straits used for international navigation — this right cannot be suspended.
- UNCLOS Article 44: States bordering a strait (Iran and Oman, in Hormuz's case) shall not hamper transit passage and shall give appropriate publicity to any danger to navigation within the strait.
- Iran ratified UNCLOS in 1982 (though its internal laws have sometimes been inconsistent with UNCLOS provisions). The US, while not a party to UNCLOS, recognises the customary international law right of transit passage as binding.
- The strait has a total width of about 54 km at its narrowest point; the navigable shipping lanes are two 3.2 km-wide channels (one inbound, one outbound) separated by a 3.2 km median zone.
- Iran's position has historically been that it has the right to close the strait in a state of war — a claim not accepted under international law.
Connection to this news: Larijani's conditional framing ("peace for all or defeat for warmongers") is Iran's attempt to justify its legal violation of transit passage under UNCLOS by framing it as a wartime necessity and a bargaining chip for ceasefire negotiations.
Ali Larijani — Role and Institutional Context
Ali Larijani is one of Iran's most experienced and influential senior officials, having served across multiple key institutions of the Islamic Republic. He served as Speaker of the Iranian Parliament (Majlis) from 2008 to 2020 and as Secretary of the Supreme National Security Council (SNSC) from 2005 to 2007 — roles that gave him direct oversight of nuclear negotiations and national security strategy.
- The Supreme National Security Council (SNSC) is the highest national security body in Iran, constitutionally established under Article 176 of Iran's Constitution. It is chaired by the President and includes military commanders, intelligence chiefs, and senior ministers.
- Larijani is considered a pragmatist within Iran's hardline establishment, having historically represented a faction open to negotiations while remaining firmly within the revolutionary system.
- His family has deep ties to the Islamic Republic: his brother Sadeq Larijani served as head of the judiciary; his late brother Mohammad-Javad Larijani was a key human rights official.
- Larijani's public statements carry strategic weight — they are calculated diplomatic signals, not mere rhetoric, given his seniority.
Connection to this news: Larijani's framing of Hormuz as offering two paths (peace or defeat) is a classic Iranian negotiating signal — the message is directed not just at the US but at regional powers and international community: Iran is willing to de-escalate if its core demands are met, but will escalate if attacked further.
US-Iran Relations — Historical Flashpoints at the Hormuz
US-Iran tensions over the Strait of Hormuz have a long history. During the Iran-Iraq War (1980-88), the US intervened to protect Kuwaiti tankers re-flagged as American vessels (Operation Earnest Will, 1987-88) — the largest US naval convoy operation since World War II. Iran mined Gulf waters and the US destroyed Iranian oil platforms in response (Operation Praying Mantis, 1988).
- Operation Earnest Will (1987-88): US Navy convoyed re-flagged tankers after Iranian attacks; led to undeclared naval war with Iran.
- Operation Praying Mantis (April 18, 1988): Largest US surface naval engagement since WWII; US sank or damaged several Iranian naval vessels after Iran mined a US frigate.
- Iran's IRGC Navy specifically controls the Persian Gulf and Gulf of Oman approaches; it operates small fast-attack craft, mines, and shore-based anti-ship missiles — asymmetric tools designed to deter or inflict cost on larger US naval formations.
- Iran has previously threatened to close the Hormuz in 2011-12 (during nuclear sanctions), 2018 (after US withdrawal from JCPOA), and 2019 (after US sanctions escalation) — but did not follow through in those instances.
Connection to this news: The current blockade marks the first time Iran has actually closed the Strait of Hormuz in practice, not merely threatened to — escalating a long-standing strategic bluff into a live confrontation with direct global economic consequences.
