Trump Blockade of Iran Ports Risks Widening War to High Seas

US President Donald Trump’s threat to blockade the Strait of Hormuz after talks with Iran collapsed over the weekend risks widening a war now entering its seventh week, lifting oil prices and raising the prospect of further economic pain around the globe.

The US military said it would implement a blockade of all maritime traffic entering and exiting Iranian ports at 10 a.m. on Monday Washington time, adding that it would allow other vessels to transit the Strait of Hormuz if they’re not stopping in the Islamic Republic. Iran’s military adviser to the supreme leader, Mohsen Rezaee, has said the nation “will not allow” such an embargo and says it has “great untapped leverage to counter it.”
