SUBJECT: Final Report, OSD Vietnam Task Force

On June 17, 1967, Secretary Robert S. McNamara directed that a Task Force be formed to study the history of United States involvement in Vietnam from World War II to the present. Mr. McNamara's guidance was simply to do studies that were "encyclopedic and objective." With six full-time professionals assigned to the Task Force, we were to complete our work in three months. A year and a a half later, and with the involvement of six times six professionals, we are finally done to the tune of thirty-seven studies and fifteen collections of documents contained in forty-three volumes.

In the beginning, Mr. McNamara gave the Task Force full access to OSD Files, and the Task Force received access to CIA materials, and some use of State Department cables and memoranda. We had no access to White House files. Our guidance prohibited personal interviews with any of the principal participants.

The result was not so much a documentary history, as a history based solely on documents — checked and rechecked with ant-like diligence. Pieces of paper, formidable and suggestive by themselves, could have meant much or nothing. Perhaps this document was never sent anywhere, and perhaps that one, thought commented upon, was irrelevant. Without the memories of people to tell us, we were certain to make mistakes. Yet, using those memories might have been misleading as well. This approach to research was bound to lead to distortions, and distortions we are sure abound in these studies.

To bring the documents to life, to fill in gaps, and just to see what the "outside world" was thinking, we turned to newspapers, periodicals, and books. We never used these sources to supplant the classified documents, but only to supplement them. And because these documents, sometimes written by very clever men who knew so much and desired to say only a part and sometimes written very openly but also contradictorily, are not immediately self-revealing or self-explanatory, we tried both to have a number of researchers look at them and to quote passages liberally. Moreover, when we felt we could be challenged with taking something out of context, we included the whole paper in the Documentary Record section of the Task Force studies (Parts V and VI. A and B). Again seeking to fend off inevitable mistakes in interpretation and context, what seemed to us key documents were reviewed and included in several over-lapping in substance, but separate, studies.
