Book excerpt: Pulitzer-prize winning author David Halberstam's eyewitness account provides a riveting narrative of how the United States created a major foreign policy disaster for itself in a faraway land it knew little about. In the introduction to this edition, historian Daniel J. Singal supplies crucial background information that was unavailable in the mid-1960s when the book was written. With its numerous firsthand recollections of life in the war zone, The Making of a Quagmire penetrates to the essence of what went wrong in Vietnam. Although its focus is the Kennedy era, its analysis of the blunders and misconceptions of American military and political leaders holds true for the entire war.
