Seized oil tanker in international waters without clear legal basis
December 10, 2025
Systemic Escalation
Founders' Principles Violated
Guardrails Violated
International legal norms and sovereignty principles violated.
International maritime law and flag state rights violated.
UN Charter principles and Security Council authorization requirements violated.
Established diplomatic channels and protocols bypassed.
Trigger
US military operation 'Operation Southern Spear' launched to intercept and seize oil tankers carrying Venezuelan crude oil, targeting 'dark fleet' vessels attempting to evade sanctions.
Action Taken
US forces boarded and seized the oil tanker 'Skipper' carrying approximately 1.8 million barrels of Venezuelan crude oil in international waters near Venezuela on December 10, 2025. Operation conducted without Venezuelan consent and without clear UN mandate. Additional tankers (including 'Veronica') seized in subsequent operations.
In His Own Words
"This is a lawful action under US sanctions law, aimed at combating illegal oil shipments."
"The tanker was sanctioned and part of a shadow fleet evading sanctions."
What's Wrong
Maritime seizure operation conducted in international waters without clear legal basis under international maritime law. No UN Security Council authorization. Venezuela called it 'international piracy' and violation of sovereignty. Operation bypassed diplomatic channels and international legal processes.
Impact
International: Sets precedent for maritime seizures based on unilateral sanctions enforcement. Diplomatic: Venezuela and other nations condemn action as piracy, damaging international relations. Economic: Seizure of 1.8 million barrels of oil affects Venezuelan economy and global oil markets. Legal: Questions about legality of seizing ships in international waters based on domestic sanctions.

Background
Operation Southern Spear was launched to intercept 'dark fleet' oil tankers carrying Venezuelan crude oil to evade US sanctions. The operation involved boarding and seizing multiple tankers in international waters. Venezuela and international law experts questioned the legality of seizing ships in international waters based solely on US domestic sanctions law.
Why Level 4?
Systemic escalation: International maritime operation without clear legal basis, affecting multiple countries and systems. Multiple guardrails bypassed: International maritime law, UN Charter, diplomatic channels, sovereignty principles. Measurable harm to international order and legal norms.
