Iran’s Closure of Strait of Hormuz Shakes Global Oil Markets

Iran has blocked the Strait of Hormuz, a critical maritime chokepoint that previously handled approximately one-fifth of global oil supplies. Tehran has indicated it will not reopen the waterway without concessions from the United States, following a joint Israeli-American military action launched on February 28.

The blockade follows a strategic miscalculation by the U.S. administration regarding Iran’s capacity for retaliation. Netanyahu reportedly convinced the U.S. president that Iran lacked the ability to strike American interests in the region or block the Strait of Hormuz.

These assessments proved incorrect. Iran responded by saturating defense systems with low-cost drones and hypersonic ballistic missiles while simultaneously closing the strait to disrupt the global economy, The Conversation reports.

Internal U.S. Warnings and Intelligence Failures

The risk of a prolonged conflict was flagged internally before the February 28 strikes. The Conversation reports that Dan Caine warned Donald Trump that such strikes were risky and could lead to an enduring conflict.

U.S. intelligence evaluations had also predicted that Tehran would focus its reprisals on regional targets. These assessments specifically identified U.S. bases, Gulf allies, and critical energy chokepoints, including the Strait of Hormuz, as likely targets, according to The Conversation.

The current impasse has created political friction within the United States. The Conversation notes that voices within both the Democratic camp and the MAGA movement are criticizing the conflict, suggesting the war is being conducted for the benefit of Tel Aviv rather than Washington.

Iranian Defense Doctrine and Attrition Strategy

Analysts attribute Iran’s ability to withstand the offensive to a “mosaic defense” doctrine established in the 2000s. According to The Conversation, this strategy disperses command structures to ensure operational continuity even after the removal of high-ranking officials.

Iran has prepared for a war of attrition designed to deplete enemy resources faster than they can be replaced. Alain Chouet, former head of security intelligence at the DGSE, told The Conversation that the Iranian military, while relying on 1970s-era equipment unsuitable for conventional operations, is equipped to wait on the ground and inflict heavy losses on any invading force.

Chouet noted that Iran’s population of 90 million and its vast territory make it a significantly different challenge than previous conflicts in Iraq, Somalia, or Syria.

Operational Challenges for U.S. Forces

The physical geography of Iran has complicated U.S. military objectives. Olivier Dujardin, a specialist in electronic warfare and electromagnetic intelligence, stated to The Conversation that Iran has buried many of its missile installations and hidden production facilities in mountains.

This concealment left U.S. forces with few legitimate targets, leading to strikes on oil refineries and power plants. Dujardin further noted that these operations have resulted in the heavy consumption of munitions.

The conflict currently benefits Russia, according to analysis provided by The Conversation, as the U.S. remains locked in a strategic stalemate with Tehran.
