Former U.S. President Donald Trump has directed aides to prepare for a “prolonged blockade of Iran,” according to U.S. Officials cited by the Wall Street Journal on Tuesday. The reported request signals a potential escalation of pressure on Iran should Trump return to office, though the precise scope and implementation of such a blockade remain undefined.
The Wall Street Journal’s reporting indicates that discussions involved examining the legal justifications for a blockade, as well as potential logistical challenges. Sources familiar with the deliberations emphasized that the planning is preliminary and contingent on the outcome of the November presidential election. The officials, speaking on condition of anonymity, did not detail specific triggers for initiating a blockade, but suggested it would be considered in response to Iran’s continued nuclear program and support for regional proxies.
A complete blockade would represent a significant departure from current U.S. Policy, which relies on a combination of sanctions, diplomatic pressure, and military deterrence. While the U.S. Maintains extensive sanctions targeting Iran’s oil exports, financial sector, and key industries, a blockade would involve actively preventing all maritime traffic to and from Iranian ports. Such a move would almost certainly disrupt global oil markets and could be interpreted as an act of war.
The Biden administration has pursued a policy of “strategic patience” toward Iran, attempting to revive the 2015 Joint Comprehensive Plan of Action (JCPOA), commonly known as the Iran nuclear deal. The JCPOA placed limits on Iran’s nuclear program in exchange for sanctions relief. However, negotiations have stalled, and Iran has significantly advanced its nuclear capabilities since the U.S. Unilaterally withdrew from the agreement in 2018 under Trump.
Experts in international law suggest that a full blockade of Iran would face significant legal hurdles. Under international maritime law, a blockade is generally permissible only as an act of war or with the authorization of the United Nations Security Council. Given Russia and China’s likely veto power, securing UN authorization is considered highly improbable. The U.S. Would likely argue that a blockade is justified as a measure of self-defense, citing Iran’s support for groups that have attacked U.S. Forces and allies in the region.
The potential economic consequences of a blockade are substantial. Iran is a major oil producer, and a disruption to its exports would likely drive up global oil prices. The Strait of Hormuz, a narrow waterway through which approximately 20% of the world’s oil supply passes, is located near Iran and would be a key chokepoint in any blockade scenario. Disruptions to shipping through the Strait of Hormuz could have a cascading effect on the global economy.
The Iranian government has not yet officially responded to the Wall Street Journal report. However, Iranian officials have consistently warned that any attempt to disrupt Iran’s economy or interfere with its nuclear program would be met with a strong response. In recent years, Iran has increased its military capabilities, including its ballistic missile program and its naval presence in the Persian Gulf.
The U.S. Navy’s Fifth Fleet, based in Bahrain, is responsible for maintaining security in the Persian Gulf and surrounding waters. Any attempt to implement a blockade of Iran would require a significant U.S. Naval presence in the region, potentially increasing the risk of direct confrontation. The U.S. Military has conducted numerous exercises in the Persian Gulf in recent years, demonstrating its ability to project power in the region.
As of Wednesday morning, the White House has not issued a formal statement regarding the report. A spokesperson for the National Security Council stated that the administration is aware of the reporting and is monitoring the situation closely. The State Department declined to comment on the specifics of the reported discussions, reiterating the administration’s commitment to diplomacy and de-escalation.
