Iran Claims Hormuz Sovereignty While Selectively Granting Passage — The Strait as Day 26 Diplomatic Weapon

The Strait of Hormuz became a defining Day 26 diplomatic battlefield. Iran formally demanded sovereignty over the strait — a maximalist claim that goes beyond de facto control to challenge UNCLOS transit passage rights — while simultaneously demonstrating its selective control by granting safe passage to a Thai-flagged tanker under diplomatic coordination with Bangkok. Iran's naval commander declared the USS Abraham Lincoln under 'constant monitoring,' and the IRGC fired 101 missiles at the carrier the previous day. The IEA reported Hormuz traffic has collapsed 90% since the conflict began. The WTO warned one-third of global fertiliser supplies normally transit the strait, threatening food scarcity in import-dependent regions. Iran's sovereignty claim and selective-passage capability establish a powerful negotiating hand: the 15-point US plan's Hormuz safe-passage guarantee clause requires Iran to surrender this leverage. Iran's first public ceasefire condition — a 'concrete guarantee' the war won't restart — frames Hormuz reopening as contingent on US credibility, not just signing. US forces (7,000 troops, including 82nd Airborne) are now positioned near Kharg Island, Iran's primary crude export terminal — the counterpressure to Iran's Hormuz leverage.
