Nuremberg and Vietnam: An American Tragedy is a 1970 book written by Telford Taylor, the Chief Counsel Prosecutor at the Nuremberg Trials. Introduction Nuremberg and Vietnam: An American Tragedy is an examination of the United States' conduct of the Vietnam War in comparison to the actions taken by Nazi Germany during the Second World War. Taylor chose as the epigraph to the book an excerpt from a 1946 statement by Gen. Douglas MacArthur confirming the death sentence imposed by a U. S. military commission on Japanese General Tomoyuki Yamashita: Telford Taylor, was once the Chief Counsel Prosecutor at the war crimes trials of Nazi leaders in Nuremberg, Germany from 1946–1949. In that capacity, Taylor helped to establish the laws by which Nazi war criminals would be tried for their crimes. Synopsis The book begins with a lengthy history of war crimes beginning with the "knightly chivalry" of the medieval period. These rules were put into place in order to minimize unnecessary cruelties during the course of warfare. The rules protected civilian populations from massacre and the needless spread of disease. Thus, the blanket of immunity that protects soldiers from being held criminally responsible for murder committed during the course of warfare had to be carefully balanced so as to discourage wartime atrocities. The laws of war remained largely unwritten until U.S. President Abraham Lincoln approved the "Instructions for the Government of Armies of the United States in the Field", in 1863. Concerning spies, prisoners of war, and the punishment of war crimes, this document comprising 159 articles facilitated the formation of military tribunals and later led to a demand for the formalization of international laws of warfare. Thus, international laws of warfare were codified by means of a series of treaties known as the Hague and Geneva conventions. The most important consequence of these treaties is that all nations, whether signatory or otherwise, were bound by international laws of war. The Nuremberg Trials, for which Taylor served as a leading figure, gave rise to several developments in regard to international law as applied to warfare. First, it gave international jurisdiction to the prosecution of war crimes; and second, it obligated individuals engaged in warfare to adhere to international laws of conduct over and above those of their respective armies. Of greatest importance with respect to this book, however, is that the United States as a result of its participation emerged
