The US blockade of Iran is a gamble. Will it work?
The US Blockade of Iran: A Risky Strategy. Will It Pay Off?
As the Iran conflict continues, the United States has positioned itself to enforce a maritime embargo on Gulf traffic, a maneuver it claims is feasible and less perilous than earlier alternatives. Retired Rear Admiral Mark Montgomery, when questioned by the BBC, suggested the operation could be executed with relative ease, noting that it avoids the tight confines of the Strait of Hormuz where earlier confrontations posed greater dangers.
President Trump’s recent proposals—such as seizing Kharg Island or deploying naval escorts through the Strait—highlighted a shift in strategy. However, these options carried risks of direct engagement with Iranian forces, exposing US assets to missile strikes, drone attacks, and potential minefields. In contrast, a blockade allows US warships to operate safely beyond Iranian territorial waters, monitoring and intercepting vessels as they depart or arrive at ports.
“The less confined area of the Gulf offers a safer environment for our forces,” Montgomery remarked, emphasizing the strategic advantage of a prolonged maritime presence.
With access to special forces, helicopters, and fast patrol boats, the US navy is equipped to sustain such an operation. Recent examples, like the Venezuela and Cuba blockades, as well as the Russian oil tanker Marinera seized in January, demonstrate the feasibility of these actions. US Central Command (Centcom) asserts that the current measure will target all ships entering or leaving Iranian ports, while allowing those using other ports to pass with inspections.
The effectiveness of this approach hinges on its ability to disrupt Iran’s oil exports. Since the war began, Iran has maintained its petrochemical trade, bolstering its economy despite ongoing strikes. A successful blockade could cut off this revenue stream, further straining the regime’s financial stability. Yet, Iran’s endurance in the face of prior US and Israeli assaults suggests it may be prepared to withstand additional pressure.
“They believe they can endure this,” said David Satterfield, a former US humanitarian envoy, noting that Iran anticipates economic hardships will not outweigh its strategic gains.
Shipping analysts are closely tracking the movement of vessels from Iranian ports, observing a decline in traffic as the blockade takes effect. “I’m monitoring ships exiting the area now,” said Michelle Wiese Bockmann, a maritime intelligence expert, who expressed concern about the potential for disruptions. Meanwhile, Richard Meade of Lloyd’s List reported a surge in activity following the initial announcement, with 30 identifiable transits recorded in the Strait of Hormuz—highlighting the urgency of the situation.
With a ceasefire still active, the conflict has evolved into a contest of blockades, where the global economy becomes an unintended battleground. China’s involvement in recent diplomatic talks in Islamabad may signal a broader geopolitical shift, as Beijing remains Iran’s largest oil importer. Even with substantial reserves, prolonged supply interruptions could strain China’s economic resilience, prompting pressure on Washington to ease the blockade.
Trump’s latest maneuver is a calculated risk, its consequences uncertain but potentially far-reaching. Whether it succeeds in tightening economic pressure on Iran or sparks new challenges remains to be seen.
