Created in 1947, the Central Intelligence Agency plays an important part in the nation's intelligence activities, and is currently playing a vital role in the war on terrorism. While the agency is often in the news and portrayed in television shows and films, it remains one of the most secretive and misunderstood organizations in the United States. This work provides an in-depth look into the Central Intelligence Agency and how its responsibilities affect American life. After a brief history of the agency, chapters describe its organization, intelligence/counterintelligence, covert operations, controversies, key events, and notable people.

"Foreseeing conflict between the legislative and executive branches over the proper functions of government, the Founders of the United States built into the U.S. Constitution the checks and balances that Edwin S. Corwin called "an invitation to struggle." Smist argues that congressional intelligence-oversight committees--such as Senator Church's 1975-76 committee--can, by taking up this struggle, not only handle sensitive information responsibly but help shape rational foreign policy. When Congress is shut out of the intelligence process-as in President Carter's abortive Iran rescue mission and Reagan's Iran-Contra affair-the results can be catastrophic. Smist's detailed analysis of congressional oversight of U.S. intelligence from Pearl Harbor through Iran-Contra is based largely on his interviews with participants, including senators, representatives, and executive-branch officials. The analysis is informed by Smist's dialectical model of "institutional" (conservative, supportive) versus "investigative" (radical, questioning) oversight, which allows him to uncover the frequently obscured historical value of previous Senate and House investigative committees. For example, the Pike committee, 1975-76, even though its final report was suppressed by the House, was able to elicit then Secretary of State Kissinger's admission of presidential control over covert actions, thus shattering the doctrine of "plausible deniability." Because these committees continue to wrestle with the principles underlying government, their unfolding drama is meaningful for the student of constitutional history. This book provides new conceptual tools for the study of intelligence oversight and gives the direct testimony of key participants, making it important not only as political science but as history." --

In 2000 the Washington Post listed The Agency as one of the ten best books on Intelligence in the twentieth century, calling it “An encyclopedic and fair-minded overview of the agency into the 1980s.” A history of the CIA from its intrepid early days to becoming a mature bureaucracy riddled with scandal and scrutiny. During World War II “Wild Bill” Donovan started the Office of Special Services (OSS) and gave the CIA its original image: dashing, Ivy League, and Eastern Establishment. Successive CIA Directors covered in the book were Allen Dulles, Richard Helms, William Colby and William Casey. “The Agency is the first comprehensive history of the CIA, a book designed, in its author’s words, to get away from ‘contemporary demonology’ and to place the CIA firmly within the context of its time... a dazzling, panoramic overview of the CIA’s history. [Ranelagh] mixes keen insights into the organization and the people who ran it with superb accounts of specific crises and operations. This brilliant book is so rich both in detail and generalization that even a reader unfamiliar with the history of the CIA will find it hard to put down... the book pursues many... themes, such as organizational changes within the agency and shifts in its sense of mission, its relationship with presidents and their advisers and other intelligence agencies, the history of specific projects and operations, and the general mood within both the CIA and the government and nation at large. The result is a complex tapestry, full of new information and fresh generalizations.” — Reviews in American History “A massive history of the CIA... Ranelagh... has a good feel for the murky world of intelligence, and has constructed quite a readable work... [he] conducted scores of interviews with insiders and studied more than 7,000 pages of classified and formerly classified documents... Great reading and a valuable reference for students of government bureaucracy and intelligence work.” — Kirkus “Ranelagh... provides here a major overview of the Central Intelligence Agency from its founding in 1947 to [1987]. Based largely on hundreds of interviews, the book examines the personality and policies of each director in the context of the times.” — Publishers Weekly “[A] comprehensive examination of the CIA... Unlike most books on the nearly 40-year-old spy organization, The Agency is not a diary of old war stories or a flashy expose; it is a thoughtful analysis of the CIA from gestation to middle age... An important difference between The Agency and many other scholarly treatments of intelligence gathering is the extensive use of quotes from both on-the-record and unattributed sources, as well as documents obtained under the Freedom of Information Act.” — The New York Times “A thoughtful analysis of the CIA from its beginnings, arguing that dependence on technology has crippled American intelligence.” — The New York Times “Mr. Ranelagh, a British television producer, has written the best comprehensive history of the CIA. He is in control of the massive secondary literature, has used the Freedom of Information Act effectively, interviewed widely, and mined congressional sources. The tone is critical but detached, devoid of both the muckraking passion of the left and the self-congratulatory approach of the old-boy network. A fine book.” — Foreign Affairs “The Agency is without a doubt the finest, best-documented, and most entertainingly written study of the Central Intelligence Agency (CIA) of which I know. It traces the agency from its first gleam in the eye of Wild Bill Donavan through the first term of William Casey on behalf of President Reagan... a genuine literary and stylistic accomplishment.” — Annals of the American Academy of Political and Social Science
