National Intelligence Authority (United States): The National Intelligence Authority (NIA) was the United States Government authority responsible for monitoring the Central Intelligence Group (CIG), the successor intelligence agency of the Office of Strategic Services established by President Harry S. Truman's Executive Letter of 22 January 1946 in the aftermath of World War Two.  The National Intelligence Authority and Central Intelligence Group were both replaced respectively by the National Security Council and the Central Intelligence Agency under the National Security Act of 1947 implemented on the 18 September 1947.

John E. McLaughlin: John Edward McLaughlin (born June 15, 1942) is the former Deputy Director of Central Intelligence and former Acting Director of Central Intelligence.  His CIA career lasted more than 30 years starting in 1972 with a focus on European, Russian, and Eurasian issues in the Directorate of Intelligence.  From 1984 to 1985, he served a rotational tour at the State Department in the Bureau of European and Canadian Affairs, where he was responsible for following European relations with the Middle East, Central America, and Africa.  He served as Deputy Director and Director of the Office of European Analysis from 1985 to 1989; Director of Slavic and Eurasian Analysis from 1989 to 1995; Deputy Director for Intelligence, Vice Chairman for Estimates of the National Intelligence Council, and Acting Chairman of the National Intelligence Council from 1995 to 1997; and Deputy Director for Intelligence from 1997 to 2000 — heading up the Agency's analytical corps.

The Spymasters: The Spymasters: CIA In the Crosshairs is a 2015 documentary film which covers the experience of the Central Intelligence Agency as seen through the eyes of the twelve living CIA directors, all of whom were interviewed for the film.  Directed and produced by Jules Naudet, Gedeon Naudet, and Chris Whipple, the documentary was aired on Showtime in the United States November 28, 2015.  The project involved interviews which took more than a year and a half to conduct, beginning with former Director of Central Intelligence and 41st president George H. W. Bush and ending with George Tenet.  The film also contains interviews with numerous other government figures and addresses the September 11 attacks, Iraq War, and weapons of mass destruction controversies, as well as drone strikes.  The disagreements among the former directors underscore the issues confronting the Agency, political leaders, and the American people.  The former directors and the current director, however, seem to agree when it comes to War on Terror: "You can not kill your way out of this."

Intelligence Star: The Intelligence Star is an award given by the Central Intelligence Agency to its officers for "voluntary acts of courage performed under hazardous conditions or for outstanding achievements or services rendered with distinction under conditions of grave risk".  The award citation is from the Director of the Central Intelligence Agency and specifically cites actions of "extraordinary heroism".  It is the third-highest award given by the Central Intelligence Agency, behind the Distinguished Intelligence Cross and Distinguished Intelligence Medal, and is analogous to the Silver Star, the US military award for extraordinary heroism in combat.  Only a few dozen people have received this award (most posthumously), making it one of the rarest valor awards awarded by the US government.

Saddam Hussein and al-Qaeda link allegations: Saddam Hussein and al-Qaeda link allegations were made by the U.S. government officials who claimed that a highly secretive relationship existed between former Iraqi President Saddam Hussein and the radical Islamist militant organization Al-Qaeda from 1992 to 2003, specifically through a series of meetings reportedly involving the Iraqi Intelligence Service (IIS).  In the lead up to the Iraq War, U.S. President George W. Bush alleged that Iraqi President Saddam Hussein and militant group al-Qaeda might conspire to launch terrorist attacks on the United States, basing the administration's rationale for war, in part, on this allegation .  The consensus of intelligence experts has been that these contacts never led to an operational relationship, and that consensus is backed up by reports from the independent 9/11 Commission and by declassified Defense Department reports as well as by the Senate Select Committee on Intelligence, whose 2006 report of Phase II of its investigation into prewar intelligence reports concluded that there was no evidence of ties between Saddam Hussein and al-Qaeda.  Critics of the Bush Administration have said Bush was intentionally building a case for war with Iraq without regard to factual evidence.  On April 29, 2007, former Director of Central Intelligence George Tenet said on "60 Minutes", "We could never verify that there was any Iraqi authority, direction and control, complicity with al-Qaeda for 9/11 or any operational act against America, period."

James Woolsey Jr., and John M. Deutch.  Admiral Studeman retired from the Navy in 1995 after almost 35 years of service.  Between 1988 and 1992 he was director of the National Security Agency; he was the Director of Naval Intelligence, from September 1985 to July 1988.

James Woolsey Jr.: Robert James "Jim" Woolsey Jr. (born September 21, 1941) is a national security and energy specialist and former Director of Central Intelligence who headed the Central Intelligence Agency from February 5, 1993, until January 10, 1995.
