Book excerpt: "This is a study of U.S. government policymaking during the 30 years of the Vietnam war, 1945-75, beginning with the 1945-1960 period. Although focusing on the course of events in Washington and between Washington and U.S. officials on the scene, it also depicts major events and trends in Vietnam to which the U.S. was responding, as well as the state of American public opinion and public activity directed at supporting or opposing the war."--Preface.
