US military asserts control of Hormuz, choking Iran's trade artery | DW News

Key Concepts

• Naval Blockade: A strategic operation to prevent vessels from entering or leaving a nation's ports.
• Maritime Superiority: A military condition where one force has sufficient control over a maritime area to conduct operations, though it falls short of absolute "supremacy."
• Strait of Hormuz: A critical global chokepoint for oil and gas transit.
• Asymmetric Warfare: Conflict between belligerents whose relative military power differs significantly, often involving unconventional tactics.
• Law of Naval Warfare: International legal framework requiring blockades to be announced, impartial, effective, and inclusive of provisions for neutral vessels and relief supplies.
• Mine Countermeasures (MCM): Specialized naval operations to clear sea mines, essential for maintaining safe passage in contested waterways.

1. The US Naval Blockade of Iran

The US Central Command (CENTCOM) has announced the implementation of a full naval blockade on Iranian ports, effectively halting maritime trade. This action follows Iran’s closure of the Strait of Hormuz during a month-long conflict with the US and Israel.

• Strategic Intent: Experts suggest the blockade serves as a bargaining chip for upcoming diplomatic negotiations and a method to cripple Iran’s oil and gas revenue.
• Military Reality: Ralph Thiele, head of Euro Defense Germany, clarifies that while the US claims "maritime superiority," this does not equate to total control. The blockade is currently manageable due to low traffic volume, but sustaining it would significantly tax US naval resources.

2. Legal Framework and Compliance

Todd Huntley, Director of the National Security Law Program at Georgetown University, outlines the requirements for a lawful naval blockade:

• Requirements: To be legal under international law, a blockade must be formally announced, applied impartially to all nations, and be physically effective.
• The "Trump Factor": Huntley notes that while President Trump’s initial social media posts regarding the blockade were legally problematic, the subsequent formal announcements by CENTCOM brought the operation into alignment with the Law of Naval Warfare.
• Humanitarian Obligations: The Department of Defense Law of War manual mandates that neutral vessels carrying relief supplies must be permitted passage.

3. Military Assessment and Risks

• Escalation Potential: Thiele argues that Iran currently possesses more potential for escalation than the US. A major risk involves China, a primary consumer of Iranian oil, which could become an "ugly opponent" if its shipping interests are directly targeted.
• Regional Defense: Contrary to fears of Iranian retaliation against Gulf ports, Thiele notes that nations like the United Arab Emirates (UAE) have demonstrated high-level air defense capabilities, making them resilient against missile and drone strikes.
• Mine Warfare: The deployment of Japanese minesweepers to the Gulf highlights a critical gap in US naval planning. The withdrawal of US minesweepers prior to the conflict necessitated reliance on international partners to clear the Strait of Hormuz.

4. War Objectives and Outcomes

• Regime Change: Experts view the goal of regime change as increasingly unlikely.
• Military Degradation: The US-Israeli coalition has reportedly destroyed 80% to 90% of Iran’s ballistic missile infrastructure. While this significantly lowers Iran’s immediate military threat, it does not eliminate it, as Iran retains the capacity to rebuild over time.
• Diplomatic Outlook: Despite the ongoing blockade, diplomatic efforts are underway. Pakistan has proposed a second round of peace talks, which President Trump indicated could occur in the near future.

5. Notable Quotes

• Ralph Thiele on Military Terminology: "Superiority... means in this area that you talk about [you have more to say]. There is a higher term which is supremacy, which means in principle the other has nothing to say at all."
• Todd Huntley on Presidential Communication: "The president certainly doesn't consult manuals... which often leaves the military in an uncomfortable situation of trying to clean up and divine what the intentions of the commander in chief truly are."

Synthesis and Conclusion

The US naval blockade of Iran is a high-stakes maneuver intended to exert economic pressure and gain leverage in diplomatic talks. While the blockade is legally defensible under current CENTCOM protocols, it faces significant operational challenges, including the potential for resource exhaustion and the risk of involving global powers like China. Military experts conclude that while the blockade has successfully degraded Iran’s ballistic missile capabilities, it is not a standalone solution for victory. The ultimate success of this strategy depends on the US defining a clear "end state" and effectively coordinating with regional allies to manage the security of critical waterways like the Strait of Hormuz.
