The following is a memorandum from the Director of Central Intelligence, dated July 28, 1981, providing an East Asia Warning Assessment.

Two factors appear most important in underwriting these more extensive operations: a stable logistics base on the Thai/Kampuchean border area and access to and effective utilization of heavier weapons. [C four lines redacted under exemption B1] 5. The DK's ability to make gains has occurred in part as a result of an apparent drawing back by the Vietnamese into an essentially defensive posture. There was general agreement that the Vietnamese are experiencing serious logistics problems which make it increasingly difficult to sustain operations in the field.
