James Jesus Angleton was chief of CIA Counterintelligence from 1954 to 1975. His official position within the organization was Associate Deputy Director of Operations for Counterintelligence . Angleton was significantly involved in the US response to the purported KGB defectors Anatoliy Golitsyn and Yuri Nosenko. Angleton later became convinced the CIA harbored a high-ranking mole, and engaged in an intensive search. Whether this was a highly destructive witch hunt or appropriate caution vindicated by later moles remains a subject of intense historical debate.
According to Director of Central Intelligence Richard Helms: "In his day, Jim was recognized as the dominant counterintelligence figure in the non-communist world." Investigative journalist Edward Jay Epstein agrees with the high regard in which Angleton was held by his colleagues in the intelligence business, and adds that Angleton earned the "trust ... of six CIA directors—including Gen. Walter Bedell Smith, Allen W. Dulles and Richard Helms. They kept Angleton in key positions and valued his work."
