The Pentagon is the headquarters of the United States Department of Defense, located in Arlington County, Virginia. As a symbol of the U.S. military, "the Pentagon" is often used metonymically to refer to the Department of Defense rather than the building itself.

Designed by the American architect George Bergstrom (1876–1955), and built by Philadelphia, Pennsylvania, general contractor John McShain, the building was dedicated on January 15, 1943, after ground was broken for construction on September 11, 1941. General Brehon Somervell provided the major motive power behind the project; Colonel Leslie Groves was responsible for overseeing the project for the Army.

The Pentagon is the world's largest office building by floor area, with about 6,500,000 sq ft (600,000 m²), of which 3,700,000 sq ft (340,000 m²) are used as offices. Approximately 23,000 military and civilian employees and about 3,000 non-defense support personnel work in the Pentagon. It has five sides, five floors above ground, two basement levels, and five ring corridors per floor with a total of 17.5 mi (28.2 km) of corridors. The Pentagon includes a five-acre (20,000 m²) central plaza, which is shaped like a pentagon and informally known as "ground zero", a nickname originating during the Cold War and based on the presumption that the Soviet Union would target one or more nuclear missiles at this central location in the outbreak of a nuclear war.

Osama bin Mohammed bin Awad bin Laden ( /oʊˈsɑːmə bɪn moʊˈhɑːmɨd bɪn əˈwɑːd bɪn ˈlɑːdən/; Arabic: أسامة بن محمد بن عوض بن لادن‎, ʾUsāmah bin Muḥammad bin ʿAwaḍ bin Lādin; March 10, 1957 – May 2, 2011), was the founder of Al-Qaeda, the jihadist organization responsible for the September 11 attacks on the United States and numerous other mass-casualty attacks against civilian and military targets. He was a member of the wealthy Saudi bin Laden family, and an ethnic Yemeni Kindite.

Bin Laden was on the American Federal Bureau of Investigation's (FBI) lists of Ten Most Wanted Fugitives and Most Wanted Terrorists for his involvement in the 1998 U.S. embassy bombings. From 2001 to 2011, bin Laden was a major target of the War on Terror, with a US$25 million bounty by the Federal Bureau of Investigation. On May 2, 2011, bin Laden was shot and killed inside a private residential compound in Abbottabad, Pakistan, by U.S. Navy SEALs and CIA operatives in a covert operation ordered by United States President Barack Obama.

Daniel Ellsberg, PhD, (born April 7, 1931) is a former United States military analyst who, while employed by the RAND Corporation, precipitated a national political controversy in 1971 when he released the Pentagon Papers, a top-secret Pentagon study of U.S. government decision-making in relation to the Vietnam War, to The New York Times and other newspapers. He was awarded the Right Livelihood Award in 2006. He is also known for a fundamental contribution to decision theory, the Ellsberg paradox.

Ellsberg was born in Chicago, Illinois, in 1931, the son of Adele D. (née Charsky) and Harry Ellsberg. His parents were Jewish and had converted to Christian Science, and he was raised in a Christian Science atmosphere. He grew up in Detroit, Michigan, and attended Cranbrook Kingswood School. His mother had wanted her son to be a concert pianist but he stopped playing in July 1946 when she was killed in a car crash, together with his sister, after his father fell asleep at the wheel of the car in which the family was traveling and crashed into a culvert wall.

James George Janos (born July 15, 1951), better known as Jesse Ventura, is an American statesman, actor, author, and former professional wrestler who served as the 38th Governor of Minnesota from 1999 to 2003.

Ventura served as a Navy UDT during the Vietnam War. He later embarked on an 11-year professional wrestling career from 1975 to 1986, taking up the stage name Jesse "The Body" Ventura. He had a long tenure in the World Wrestling Federation as a performer and color commentator, and was inducted into the company's Hall of Fame in 2004. After leaving wrestling, Ventura began a successful film career, appearing in films such as 1987's Predator.

Ventura first entered politics as Mayor of Brooklyn Park, Minnesota from 1991 to 1995. He ran as the Reform Party candidate in the Minnesota gubernatorial election of 1998, running a campaign centered on grassroots events and unusual ads that implored citizens not to "vote for politics as usual". The campaign was successful, and Ventura served from January 4, 1999, to January 6, 2003, without running for a second term.
