Preface
The
National Intelligence Council (NIC) is delighted to
publish this historic collection of intelligence documents
related to the Vietnam War. The documents— 38
in this book and 174 in the companion CD— show
how the US intelligence Community viewed critical developments
over a 27-year period, ranging from analysis of the
implications of the post-World War II breakup of colonial
empires to the Communist takeover of Saigon in 1975.
A number of these documents were declassified and published
in other circumstances, but many are being made public
here for the first time. As such, they undoubtedly will
be of immense interest and value to historians and scholars,
academics and diplomats, and comprise in sum a unique
historical record of a challenging and controversial
chapter in US foreign relations.
The documents are estimative intelligence products, that is, reports that projected the impact of current trends into the future to give policymakers and military commanders a heads-up about where events were likely to lead and their probable impact on US security interests. Because they reflected the careful scrutiny and final agreement on conclusions by various Intelligence Community analysts and agencies, they were considered the most authoritative assessments of the Intelligence Community.
Any
collection of this magnitude can only be the product
of extensive collaboration. Work started in September
2004 under the auspices of NIC Chairman Robert Hutchings
and the Information Review Office team of the Director
of Central Intelligence. We are particularly grateful
to the editors and their advisors for their selection
of the documents. The same professional team performed
similar functions for the publication of Tracking
the Dragon: National Intelligence Estimates on China
During the Era of Mao, 1948-1976. We thank Professor
Lloyd Gardner of Rutgers University, a renowned academic
authority on the Vietnam War, for his masterful introduction
to this volume. Within the NIC, Mathew Burrows and his
analytic and production staff helped turn the documents
into a professionally finished book, and the CIA's Imaging
and Publishing Support Service provided the usual high-quality
printing.
Finally, we wish to recognize with this publication the signal contributions of a generation of senior officers and analysts from the various agencies of the US Intelligence Community.

Vice Chairman, National Intelligence Council
