The US blockade of Iran is a gamble. Will it work?

The US Blockade of Iran: A Strategic Gamble, Will It Pay Off?

The US military’s ability to enforce a naval blockade in the Gulf has been confirmed, but the real challenge lies in determining its purpose. Retired Rear Admiral Mark Montgomery, speaking to the BBC, suggested that such an operation is achievable and poses fewer risks than other alternatives. “It’s less risky than confronting Iranian forces directly and risking a convoy,” he explained, highlighting the strategic advantage of maintaining a safe distance from hostile activity.

Recent proposals by President Trump, such as capturing Kharg Island or escorting oil shipments through the Strait of Hormuz, could have led to more immediate confrontations. These moves would have exposed US assets to missile strikes, drone attacks, and potential minefields. By contrast, a blockade allows warships to patrol remotely, monitoring traffic from Iranian ports and intercepting vessels without direct engagement. “Operating off the coast of the Gulf of Oman reduces the danger compared to the narrow confines of the Strait,” Montgomery emphasized.

Historical examples, like past blockades of Venezuela and Cuba, demonstrate the US’s readiness for such tactics. The recent seizure of the Russian oil tanker Marinera in the northern Atlantic further illustrates the feasibility of intercepting ships across vast waters. However, the effectiveness of this strategy remains uncertain. While a successful blockade could disrupt Iran’s oil exports and strain its economy, the regime has shown remarkable endurance under sustained attacks from the US and Israel.

David Satterfield, a former US special envoy, argues that Iran may believe it can endure the economic pressure. “They think the US will suffer from rising oil prices, and Gulf states will urge them to reopen the Strait,” he said. Despite strategic reserves, China—the world’s largest importer of Iranian crude—could feel the strain of prolonged supply disruptions. This dynamic might influence Washington’s decision-making, as Beijing’s support could be critical in easing tensions.

As of now, shipping activity through the Strait of Hormuz has slowed, with experts closely tracking vessel movements. “I’m observing a noticeable decrease in traffic,” noted maritime intelligence analyst Michelle Wiese Bockmann. Richard Meade, editor-in-chief of Lloyd’s List, reported a surge in transits following Trump’s initial announcement, with around 30 vessels flagged as passing through the Strait. “It seemed like a rush to escape,” he observed. If the blockade continues, the pace of these movements could decline significantly.

With a ceasefire still in effect, the conflict has shifted from direct combat to a contest of maritime control. China’s involvement in diplomatic talks in Islamabad may signal a broader effort to mediate and keep the Strait open. Yet, the outcome hinges on whether the US can enforce its strategy effectively. As the global economy bears the brunt of this standoff, the success of the blockade will determine whether it becomes a turning point or another setback for Tehran.
