US naval blockade on Iran is an 'illegal act of war', analyst says

Key Concepts

• Strait of Hormuz: A critical maritime chokepoint where the seizure of cargo ships occurred.
• Naval Blockade: A military action preventing the passage of goods, which Iran characterizes as an "act of war" under international law.
• Unilateral Sanctions: Economic restrictions imposed by the U.S. Congress without UN or international mandate, specifically regarding $20 billion in frozen Iranian assets.
• Zero Enrichment: A U.S. policy demand requiring Iran to cease all uranium enrichment activities.
• Tactical Nuclear Weapons: Small-scale nuclear devices that the U.S. is speculated to be considering for use against Iran’s underground missile production facilities.

1. Maritime Tensions and Diplomatic Standoff

The Islamic Revolutionary Guard Corps (IRGC) has seized two cargo vessels, the MSC Franchesca and the Epimenondes, in the Strait of Hormuz. Iran justifies these seizures by alleging the ships operated without authorization and manipulated their navigation systems. Simultaneously, the U.S. has extended a ceasefire to facilitate peace negotiations; however, Iran maintains that talks are contingent upon the lifting of the U.S. naval blockade on Iranian ports.

2. Perspectives on Negotiations and International Law

Professor Fouad Izadi of the University of Tehran argues that the U.S. approach lacks the "good faith" required for legitimate international negotiations.

• Legal Argument: Izadi asserts that blockading a country is an act of war under international law, making it contradictory to engage in peace talks while maintaining such a blockade.
• Skepticism: There is a prevailing sentiment in Iran that the U.S. is not genuinely seeking peace but is instead using the ceasefire to "buy time" and prepare for further military strikes.

3. Proposed Gestures for De-escalation

Professor Izadi outlined specific actions the U.S. could take to signal a genuine commitment to peace:

• Asset Release: Unfreezing over $20 billion in Iranian assets currently held in foreign banks, which Iran views as illegal, unilateral sanctions.
• Rhetorical Shift: A reduction in hostile or profane rhetoric from President Trump, which is seen as a prerequisite for serious diplomatic engagement.

4. The "Zero Enrichment" Policy and Nuclear Concerns

The U.S. has pivoted to a demand for "zero enrichment" of uranium. Professor Izadi provided critical context regarding this stance:

• Historical Context: Iran previously offered to remove enriched uranium from its soil during the UN General Assembly in September and again in February to avoid conflict.
• The War Calculus: Following the death of over 3,200 civilians and the destruction of infrastructure, the Iranian perspective has shifted. There is a widespread belief that the U.S. may be considering the use of tactical nuclear weapons to destroy Iran’s underground missile production facilities.
• Strategic Deterrence: Izadi notes that if the U.S. were to use nuclear weapons against Iran, it would provide Iran with a strategic justification to develop its own nuclear arsenal. Consequently, Iran is now highly cautious about conceding its enriched uranium, fearing that doing so would leave it vulnerable to a nuclear strike.

5. Synthesis and Conclusion

The situation remains a high-stakes stalemate defined by deep-seated distrust. While the U.S. seeks to neutralize Iran’s nuclear capabilities through a "zero enrichment" policy, Iran views this demand—coupled with the ongoing naval blockade—as a precursor to a potential nuclear attack. The path to diplomacy is currently obstructed by the U.S.'s refusal to lift the blockade and release frozen assets, and Iran’s reluctance to repeat past concessions that it now believes would invite further military aggression.
