History

Historical Context

The Gulf of Tonkin Incident in August 1964 marked a pivotal escalation in U.S. involvement in Vietnam, following President Lyndon B. Johnson's claims of unprovoked attacks on American destroyers. This led to the Gulf of Tonkin Resolution, granting Johnson broad military powers. The recent sinking of the IRIS Dena by a U.S. submarine highlights ongoing tensions, echoing Cold War dynamics and implicating allies like Australia through the AUKUS pact.
