OPLAN 34A

A program of covert operations against North Vietnam designed to convince Hanoi to desist from supplying and supporting the Viet Cong in South Vietnam. The measures undertaken included:
  • Electronic intelligence collection
  • Psychological operations – leaflet drops and radio broadcasts
  • Sabotage operations in North Vietnam
President Johnson approved OPLAN 34A in January 1964 and the covert actions, which began the following month, played a role in the Tonkin Gulf incident.
