US Military Strategy and Security Risks in the Strait of Hormuz

The United States is preparing military and diplomatic efforts to reopen the Strait of Hormuz after the waterway was effectively shut down following the start of Operation Epic Fury on February 28, 2026.

Iran has established a selective passage regime through the Persian Gulf chokepoint, permitting the export of its own oil and natural gas while allowing safe passage only to countries that pay a transit fee. According to reporting from Just Security on April 8, 2026, Tehran has imposed a Tehran toll booth consisting of a $2 million transit fee for commercial shipping rerouted through Iranian territorial waters.

The Iranian Foreign Minister has stated that all vessels seeking to transit the Strait must coordinate directly with Iranian armed forces, subject to unspecified technical limitations.

US Military Options and Escalation

President Donald Trump has stated that the U.S. Navy will reopen the strait and has called for international assistance. To provide the necessary force for this objective, U.S. Ground invasion forces arrived in the Middle East during the weekend of March 30, 2026, including a contingent of 5,000 marines specialized in amphibious landings.

Military analysts suggest the U.S. Has two primary options for forcibly reopening the waterway: deploying a massive naval presence or seizing territory. Some experts believe the U.S. May consider capturing Iranian islands in the Gulf, though such a ground incursion is viewed as a red line for Tehran.

Tensions escalated on March 21, 2026, when President Trump issued an ultimatum stating that Iranian power plants would be obliterated unless the strait was fully opened. The Iranian military responded by threatening to target water desalination, information technology and energy infrastructure related to the U.S. And Israel in the region.

Following the ultimatum, the U.S. President postponed strikes against the power plants for five days to facilitate ongoing discussions. By April 8, 2026, the United States had agreed to a two-week suspension of strikes against Iran, although Tehran continues to maintain de facto control over the Strait of Hormuz.

Global Economic and Security Impact

The closure of the strait, through which approximately one-fifth of the world’s oil trade normally passes, has caused oil prices to rise above $100 per barrel.

Beyond energy markets, the disruption of the waterway is cited as a risk to global food security. Iran has attacked more than 20 ships in or near the Strait of Hormuz since the conflict began.

Diplomatic and Legal Standoff

Tehran has conditioned the end of the war on the establishment of a new legal regime for the Strait of Hormuz. This demand challenges existing U.S. And global interests regarding the freedom of navigation.

Legal analysts argue that Iran’s current hold on the strait is illegal under international law. The U.S. Has pledged to help with traffic buildup in the Strait, but the operational scope of this naval commitment remains undefined.
