United States imposes twenty percent tax on all cargo passing Hormuz Strait. Trump declares American military will now secure vital Strait for global trade.

All nations using the strait must financially support American security presence there.

Americans promise free passage, except for Iranian ships or Iran-bound cargo only. Iran warns allowing American intervention equals declaration of war by regional countries.

Experts debate legality of Trump's tax and anticipate potential new regional crisis. Hormuz Strait remains essential route for world oil, increasing international tensions rapidly.
