Tensions between Russia and the United States sharply escalated after U.S. forces seized a Russian-flagged oil tanker allegedly linked to Venezuela’s shadow fleet. Moscow condemned the move as an act of piracy, with senior Russian officials issuing stark warnings, including references to possible military retaliation under Russia’s defense doctrine. The incident comes days after the arrest of Venezuelan President Nicolás Maduro, a key Russian ally, further straining relations. Washington maintains the vessel was operating under a false flag and violating sanctions, while Russia insists it had temporary authorization, raising fears of a wider geopolitical confrontation.
