The US blockade of Iran is a gamble. Will it work?
The US Blockade of Iran: A Risky Move with Uncertain Outcomes
The United States has the military capacity to impose a maritime blockade on Gulf shipping routes, but the real question lies in its strategic purpose. Retired Rear Admiral Mark Montgomery, speaking to the BBC, acknowledged the feasibility of such an operation. “It’s doable,” he said, adding that it poses fewer risks than direct confrontation. For instance, forcing Iranian forces back in the Strait of Hormuz could lead to immediate clashes, exposing U.S. assets to Iranian missiles, drones, and fast boats. Mines in the region would further complicate matters, creating a perilous environment. In contrast, a blockade allows U.S. ships to remain safely offshore in the Gulf of Oman, monitoring and intercepting vessels near Iranian ports without direct engagement.
Recent actions by President Trump, such as the potential seizure of Kharg Island or escorting convoys through the Strait, highlight the high stakes of direct military involvement. These scenarios would have placed U.S. forces in vulnerable positions, risking costly confrontations. By contrast, a blockade provides a more calculated approach, leveraging U.S. naval assets like special forces, helicopters, and fast boats to achieve the goal with minimal exposure.
Historical precedents, including blockades of Venezuela and Cuba, demonstrate the U.S. ability to execute such operations. The earlier seizure of the Russian tanker Marinera in the northern Atlantic also showcased the reach of these tactics. According to U.S. Central Command (Centcom), the latest blockade aims to restrict vessels of all nations from entering or leaving Iranian ports, though ships using non-Iranian facilities will still be allowed, provided they undergo inspection. This strategy seeks to cut off Iran’s access to critical oil exports while maintaining some level of global trade flow.
But will this approach succeed? The logic is straightforward: Iran has sustained its oil exports through the Gulf despite ongoing conflict, generating revenue that supports its economy. A successful blockade could disrupt this flow, depriving Tehran of essential funds and further straining its financial position. However, Iran has already shown remarkable endurance in withstanding a month of attacks from the U.S. and Israel. Analysts suggest that the country may be prepared to endure additional pressure, especially as a blockade could drive oil prices higher, potentially offsetting its economic losses.
“They believe they can outweigh this,” said David Satterfield, a former U.S. special envoy for Middle East humanitarian affairs. “The U.S. will feel pain from oil prices, and Gulf states may push for the Strait to remain open.”
Shipping experts are closely tracking the movement of vessels departing Iranian ports. Michelle Wiese Bockmann, a maritime intelligence analyst, noted the visible impact of the blockade. “I’m literally looking at ships that are going through now,” she remarked, expressing concern over the reduced traffic. Richard Meade, editor-in-chief of Lloyd’s List, reported a surge in ship transits through the Strait of Hormuz in the days following Trump’s announcement. “We saw a few U-turns in response to the initial declaration,” he said, highlighting the immediate reaction from the shipping industry.
With a ceasefire currently in effect, the Iran conflict has shifted into a contest between two blockades. The global economy, reliant on Gulf oil, is caught in the crossfire. China’s diplomatic influence in recent talks in Islamabad may play a key role in this dynamic. As the world’s largest importer of Iranian oil, Beijing has a vested interest in maintaining supply chains. Even with strategic reserves, prolonged interruptions could threaten its energy security. Trump’s latest maneuver, therefore, represents a calculated gamble—one that could soon reverberate across international markets.
