So here's the situation: a former U.S. president is talking about sending warships to one of the world's most important oil shipping lanes. On Saturday, Donald Trump said multiple countries will join the U.S. in dispatching naval vessels to keep the Strait of Hormuz open after what he described as Iran's attempted shutdown of the waterway. This isn't just geopolitical posturing—it's about a narrow strip of ocean that handles about one-fifth of the world's oil. When someone threatens to close that, people tend to get interested.

In a post on Truth Social, Trump said nations "affected" by the attempted closure will send ships alongside the U.S. to keep the passage "open and safe." He argued that even with Iran's forces degraded, Tehran could still harass traffic using drones, mines, or short-range missiles. Think of it as a high-stakes escort service for oil tankers.

Trump listed China, France, Japan, South Korea and the U.K. among countries he wants in the naval effort, adding "others" he said are also impacted. The goal, he said, is to remove the risk of disruption from what he called an "artificial constraint" on shipping. It's a coalition-style maritime plan built around protecting commercial traffic while anticipating those low-cost attacks.

What This Means for Oil Markets

Let's talk about why this matters. The Strait of Hormuz is a chokepoint for about 20% of global oil supply. Any threat to transit there is a direct issue for energy markets and, by extension, for anyone who buys gas or follows the stock prices of energy companies. Trump explicitly linked U.S. military choices around Iran's Kharg Island—a key oil export node about 300 miles from Hormuz—to whether Iran interferes with shipping through the strait.

In comments on Friday about recent strikes on Kharg Island, Trump said U.S. Central Command hit military targets there while leaving oil infrastructure intact for now. But he warned that could change if Iran, or another actor, tries to obstruct maritime movement. "Should Iran, or anyone else, do anything to interfere with the Free and Safe Passage of Ships through the Strait of Hormuz, I will immediately reconsider this decision," he wrote. Translation: we haven't blown up the oil facilities yet, but we're keeping that option in our back pocket.

Iran's Military Weakening Amid U.S. Pressure

Trump's narrative here is that Iran is already on the back foot. In earlier statements, he emphasized that Iran has apologized and pledged not to attack its regional neighbors, framing this as a significant capitulation following relentless U.S. and Israeli military actions. He labeled Iran as no longer the "Bully of the Middle East," suggesting this shift occurred after what he described as their first loss to surrounding countries in "thousands of years."

This historical context—whether you buy it or not—is part of the story Trump is telling about Iran's perceived military decline. His insistence on Iran's "unconditional surrender" further complicates diplomatic relations, as Iranian officials have publicly rejected external influence on their politics. The narrative of Iran's decline under pressure feeds into the broader context of securing the Strait of Hormuz, particularly as Trump calls for allied naval support.

Can Global Allies Secure the Strait?

The plan, as described, involves escorting and protecting commercial traffic while anticipating those low-cost attacks like mines or drones. Trump said U.S. forces would also keep striking along Iran's shoreline and target Iranian boats and ships. In a Fox News Radio interview with Brian Kilmeade aired on Friday, Trump said the U.S. would escort ships through the strait if needed. He also said the U.S. would hit Iran "very hard over the next week."

Beyond the naval plan, Trump urged Iran's military and those tied to the regime to lay down their arms. He also claimed, in a later post, that Iran's plans against the region and Israel are now "dead." It's a maximalist approach: assemble a coalition, show force, and demand surrender.

The High Stakes of Kharg Island's Control

To understand why Kharg Island is in the conversation, you need to know its role. The island sits about 16 miles off Iran's coast and handles about 90% of the country's oil shipments. That puts it at the center of any squeeze on Tehran's export revenue. Its location—roughly 300 miles from the Strait of Hormuz—ties the island's security directly to the wider fight over safe passage.

Trump said the U.S. has the world's most advanced weapons but chose not to destroy the island's oil facilities, while keeping that option on the table if shipping is threatened. According to his posts, the U.S. and partner navies will "soon get the Hormuz Strait OPEN, SAFE, and FREE." The message is clear: the strait stays open, one way or another, and the world's major economies apparently have a shared interest in making that happen.
