On March 17 Sullivan, as chairman of the Ad Hoc Group on Vietnam, sent Kissinger a memorandum proposing an organization for more effective coordination of psychological operations against Vietnamese Communists. (Ibid., RG 59, S/S–Ex Files: Lot 83 D 305, NSDM 63)
  2. On June 17 Sullivan sent Kissinger a memorandum with an attached paper that listed objectives and set out the themes and ground rules established by the Ad Hoc PSYOPs Committee created by NSDM 63. This paper was approved by the Ad Hoc Committee on Vietnam. In a July 6 memorandum to Kissinger analyzing the paper, Holdridge suggested that the objectives were “fairly traditional”: persuading the leadership to change its policies; increasing internal tensions, doubts, and policies; and motivating the Vietnamese people to question the wisdom of the North Vietnamese Government. Holdridge then listed the proposed targets: the top Party leadership, the Party apparatus, the North Vietnamese people, and Communist forces in the north and south. The themes developed for each target were designed to convince them that the war could not be won and policies must be changed, to increase war weariness and discouragement among troops and the population, and to cause resentment and tension between northerners and southerners. Kissinger approved the paper on July 14. (Memorandum from Holdridge to Kissinger, July 6, attaching a memorandum from Sullivan to Kissinger June 17 and a paper prepared by the Ad Hoc PSYOP Committee submitted to Sullivan on June 12; ibid., NSC Institutional Files (H-Files), Box H–216, NSDM 63)
