This book examines the events that led up to the day--March 31, 1968--when Lyndon Johnson dramatically renounced any attempt to be reelected president of the United States. It offers one of the best descriptions of U.S. policy surrounding the Tet offensive of that fateful March--a historic turning point in the war in Vietnam that led directly to the end of American military intervention. Originally published in 1977. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
