US strike on merchant vessel in Gulf of Oman exposes contested legality of Iran blockade amid great-power rivalry over Strait of Hormuz chokepoint
Original framing: “US forces disable ship ‘attempting to run’ Iran blockade in Gulf of Oman” — Al Jazeera
The 1984-1988 Tanker War provides the direct precedent: 451 commercial vessels attacked, 540,000 tons of shipping damaged, prompting US Operation Earnest Will (reflagging Kuwaiti tankers) and the 1987 UNSC Resolution 598 ceasefire. The 1988 USS Vincennes shootdown of Iran Air Flight 655 (290 dead) — initially claimed as an F-14 attack — established a pattern of US misidentification in the Strait. Britain's 19th-century 'Trucial States' treaties created the legal fiction of Gulf sheikhdoms as British-protected entities, a framework the US inherited in 1971. Iran's 1971 seizure of Abu Musa and the Tunbs, and the 1979 Revolution's repudiation of the 1975 Algiers Accord, fuel Tehran's claim that the Strait is an Iranian security frontier, not an international strait.
The US strike on a commercial vessel in the Gulf of Oman is not an isolated tactical event but a node in a 40-year system of militarized lawlessness in the Strait of Hormuz, where CENTCOM's 'freedom of navigation' operations and Iran's revolutionary naval doctrine have jointly eroded UNCLOS, endangered a thermally collapsing marine ecosystem, and structuralized the expendability of South Asian seafarer labor.
The original Al Jazeera framing — adopting CENTCOM's 'disable/blockade' vocabulary without legal interrogation — reproduces the power/knowledge structure that makes kinetic action appear as policing rather than escalation. Restoring the omitted elements — the San Remo Manual's blockade criteria, the Vincennes precedent, Oman's mediation tradition, ITF abandonment data, ROPME liability frameworks — reveals that the only durable security architecture is a regionally owned, legally binding Hormuz Code of Conduct with mandatory seafarer protections and environmental liability, mediated by the one Gulf actor (Oman) whose indigenous maritime cosmology still treats the sea as a shared commons rather than a sovereign frontier.
