This volume investigates the diplomatic objectives and strategic policy decisions of the United States government regarding Southeast Asia during the period of 1955 to 1957. The text is compiled by the Office of the Historian at the U.S. Department of State, utilizing declassified internal memoranda, telegrams, and intelligence reports to reconstruct the decision-making processes of the Eisenhower administration. It argues that U.S. policy in the region was primarily driven by the containment of communism and the stabilization of newly independent nations through economic and military aid.

Historians and political scientists utilize this series as the definitive primary source record for American foreign policy during the mid-twentieth century. The text is noted for its high academic density and serves as a foundational reference for researchers examining the origins of U.S. military intervention in Southeast Asia.
