Iran charging fees would set dangerous precedent allowing other countries to charge for passage through strategic straits worldwide, harming global trade long-term.

Mentions examples like Strait of Malacca, Tangier with Strait of Gibraltar, and even US near Greenland as potential locations for similar fees.

Immediate impact would be restricted movement through Strait of Hormuz, with Iran imposing cargo inspections and potential bans on shipments to US/Israel allies.

Restrictions mean less oil supply, leading to higher prices. World must maintain Strait of Hormuz as international waters with free trade flow.
