Louis Stephen St. Laurent (1 February 1882 – 25 July 1973) was the 12th prime minister of Canada, from 15 November 1948 to 21 June 1957. He was a Liberal with a strong base in the Catholic francophone community, from which he had long mobilised support to Prime Minister William Lyon Mackenzie King. His foreign policy initiatives transformed Canada from an isolationist ex-colony with little role in world affairs to an active "middle power".

St. Laurent was an enthusiastic proponent of Canada's joining NATO in 1949 to fight the spread of Communism, overcoming opposition from some intellectuals, the Labor-Progressive Party, and many French Canadians. The contrast with Mackenzie King was not dramatic – they agreed on most policies. St. Laurent had more hatred of communism, and less fear of the United States. He was neither an idealist nor a bookish intellectual, but an "eminently moderate, cautious conservative man ... and a strong Canadian nationalist"

Sir Winston Leonard Spencer-Churchill (30 November 1874 – 24 January 1965) was a British politician, statesman, army officer, and writer, who was Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955. As Prime Minister, Churchill led Britain to victory in the Second World War. Ideologically an economic liberal and British imperialist, he began and ended his parliamentary career as a member of the Conservative Party, which he led from 1940 to 1955, but for twenty years from 1904 he was a prominent member of the Liberal Party.

Widely considered one of the 20th century's most significant figures, Churchill remains popular in the UK and Western world, where he is seen as a victorious wartime leader who played an important role in defending liberal democracy from the spread of fascism. Also praised as a social reformer and writer, among his many awards was the Nobel Prize in Literature.

Elizabeth II (21 April 1926 – 8 September 2022), became head of the Commonwealth and queen regnant of seven independent Commonwealth countries: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon on 6 Feb 1952.

She reigned through major constitutional changes, such as devolution in the UK, Canadian patriation, and the decolonisation of Africa. Her many historic visits and meetings include a state visit to the Republic of Ireland and visits to or from five popes. Significant events have included her coronation in 1953 and the celebrations of her Silver, Golden, and Diamond Jubilees in 1977, 2002, and 2012 respectively. In 2017, she became the first British monarch to reach a Sapphire Jubilee. She is the longest-lived and longest-reigning British monarch as well as the world's longest-reigning queen regnant and female head of state, the oldest and longest-reigning monarch and the longest-serving head of state.

Dwight David "Ike" Eisenhower (October 14, 1890 – March 28, 1969) was an American army general and statesman who served as the 34th president of the United States from 1953 to 1961.

During World War II, he was a five-star general in the United States Army and served as supreme commander of the Allied Expeditionary Forces in Europe. He was responsible for planning and supervising the invasion of North Africa in Operation Torch in 1942–43 and the successful invasion of France and Germany in 1944–45 from the Western Front. In 1952, Eisenhower entered the presidential race as a Republican to block the isolationist foreign policies of Senator Robert A. Taft, who opposed NATO and wanted no foreign entanglements. He won that election and the 1956 election in landslides.

Robert Anthony Eden, 1st Earl of Avon, (12 June 1897 – 14 January 1977) was a British Conservative politician who served a relatively brief term as Prime Minister of the United Kingdom from 1955 to 1957. Having been deputy to Winston Churchill for almost 15 years, he succeeded him as the Leader of the Conservative Party and Prime Minister in April 1955, and a month later won a general election.

Eden's worldwide reputation as an opponent of appeasement, a "man of peace", and a skilled diplomat was overshadowed in 1956 when the United States refused to support the Anglo-French military response to the Suez Crisis. Two months after ordering an end to the Suez operation, he resigned as Prime Minister on grounds of ill health and because he was widely suspected of having misled the House of Commons over the degree of collusion with France and Israel.

The Vietnam War took place from 1 November 1955 to the fall of Saigon on 30 April 1975, with US involvement ending in 1973. It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The North Vietnamese army was supported by the Soviet Union, China, and other communist allies; the South Vietnamese army was supported by the United States, South Korea, the Philippines, Australia, Thailand and other anti-communist allies.

An anti-war movement gained strength in the US. Nixon appealed to the "silent majority" of Americans who he said supported the war but revelations of the My Lai Massacre, and the 1969 "Green Beret Affair" provoked national and international outrage. In 1971 the Pentagon Papers were leaked to The New York Times. The top-secret history of US involvement in Vietnam, commissioned by the Department of Defense, detailed a long series of public deceptions on the part of the US government.
