The Nuremberg principles were a set of guidelines for determining what constitutes a war crime. The document was created by the International Law Commission of the United Nations to codify the legal principles underlying the Nuremberg Trials of Nazi party members following World War II.

Principle I states, "Any person who commits an act which constitutes a crime under international law is responsible therefor and liable to punishment."

Principle II states, "The fact that internal law does not impose a penalty for an act which constitutes a crime under international law does not relieve the person who committed the act from responsibility under international law."

Principle III states, "The fact that a person who committed an act which constitutes a crime under international law acted as Head of State or responsible government official does not relieve him from responsibility under international law."

Principle IV states: "The fact that a person acted pursuant to order of his Government or of a superior does not relieve him from responsibility under international law, provided a moral choice was in fact possible to him".

Willson served in the US Air Force from 1966 to 1970, including several months as a combat security officer in Vietnam. He left the Air Force as a Captain. He subsequently became a member of Vietnam Veterans Against the War and Veterans For Peace (Humboldt Bay Chapter 56, California). Upon completion of Law School at American University in Washington, D.C., he became a member of the District of Columbia Bar. Willson has had a variety of jobs including penal consultant, prisoner rights advocate, dairy farmer, legislative aide, town tax assessor and building inspector, veteran's advocate, and small businessman.

As a trained lawyer and writer, he has documented U.S. policy in nearly two dozen countries. Since 1986, Willson has studied on-site policies in a number of countries, among them Nicaragua, El Salvador, Honduras, Panama, Brazil, Argentina, Mexico, Colombia, Ecuador, Cuba, Haiti, Iraq, Israel (and Palestinian territories), Japan, and Korea, both North and South. Documenting the pattern of policies that he says "violate U.S. Constitutional and international laws prohibiting aggression and war crimes," Willson has been an educator and activist, teaching about the dangers of these policies. He has participated in lengthy fasts, actions of nonviolent civil disobedience, and tax refusal along with voluntary simplicity.

Jeffrey Ross Toobin (born May 21, 1960) is an American lawyer, author, and legal analyst for CNN and The New Yorker.

Toobin was born in New York City, New York., the son of former ABC News and CBS News correspondent Marlene Sanders, and news broadcasting producer Jerome Toobin. He attended Columbia Grammar and Preparatory School, in New York City and attended Harvard College where he covered sports for The Harvard Crimson, using the column name "Inner Toobin." He graduated magna cum laude with a Bachelor of Arts degree in 1982 and earned a Truman Scholarship. He is also a 1986 magna cum laude graduate of Harvard Law School, where he was an editor of the Harvard Law Review.

Toobin began freelancing for The New Republic as a law student. He went on to become a law clerk to a federal judge and work as an associate counsel to Independent Counsel Lawrence E. Walsh during the Iran-Contra affair and Oliver North's criminal trial, before becoming an Assistant U.S. Attorney in Brooklyn. He then took up his post in 1993 at The New Yorker, and became the first television legal analyst in 1994, at ABC.

Joseph Raymond "Joe" McCarthy (November 14, 1908 – May 2, 1957) was an American politician who served as a Republican U.S. Senator from the state of Wisconsin from 1947 until his death in 1957. Beginning in 1950, McCarthy became the most visible public face of a period in which Cold War tensions fueled fears of widespread Communist subversion. He was noted for making claims that there were large numbers of Communists and Soviet spies and sympathizers inside the United States federal government and elsewhere. Ultimately, McCarthy's tactics and his inability to substantiate his claims led him to be censured by the United States Senate.

The term McCarthyism, coined in 1950 in reference to McCarthy's practices, was soon applied to similar anti-communist activities. Today the term is used more generally in reference to demagogic, reckless, and unsubstantiated accusations, as well as public attacks on the character and/or patriotism of political opponents.

Born and raised on a Wisconsin farm, McCarthy earned a law degree at Marquette University in 1935 and was elected as a circuit judge in 1939, the youngest in state history. At age 33, McCarthy volunteered for the United States Marine Corps and served during World War II. He successfully ran for the United States Senate in 1946, defeating Robert M. La Follette, Jr. After three largely undistinguished years in the Senate, McCarthy rose suddenly to national fame in February 1950 when he asserted in a speech that he had a list of "members of the Communist Party and members of a spy ring" who were employed in the State Department. McCarthy was never able to prove his sensational charge.

Peter "Pete" Seeger (born May 3, 1919) is an American folk singer and an iconic figure in the mid-20th-century American folk music revival. A fixture on nationwide radio in the 1940s, he also had a string of hit records during the early 1950s as a member of The Weavers, most notably their recording of Lead Belly's "Goodnight, Irene", which topped the charts for 13 weeks in 1950. Members of The Weavers were blacklisted during the McCarthy Era. In the 1960s, he re-emerged on the public scene as a prominent singer of protest music in support of international disarmament, civil rights, and environmental causes.

As a song writer, he is best known as the author or co-author of "Where Have All the Flowers Gone?", "If I Had a Hammer (The Hammer Song)", (composed with Lee Hays of The Weavers), and "Turn, Turn, Turn!", which have been recorded by many artists both in and outside the folk revival movement and are still sung throughout the world. "Flowers" was a hit recording for The Kingston Trio (1962); Marlene Dietrich, who recorded it in English, German and French (1962); and Johnny Rivers (1965). "If I Had a Hammer" was a hit for Peter, Paul & Mary (1962) and Trini Lopez (1963), while The Byrds popularized "Turn, Turn, Turn!" in the mid-1960s, as did Judy Collins in 1964, and The Seekers in 1966. Seeger was one of the folksingers most responsible for popularizing the spiritual "We Shall Overcome" (also recorded by Joan Baez and many other singer-activists) that became the acknowledged anthem of the 1960s American Civil Rights Movement, soon after folk singer and activist Guy Carawan introduced it at the founding meeting of the Student Nonviolent Coordinating Committee (SNCC) in 1960. In the PBS "American Masters" episode Pete Seeger: The Power of Song, Seeger states it was he who changed the lyric from the traditional "We will overcome" to the more singable "We shall overcome".
