Moving to the USA prior to the outbreak of war in Europe, Farago worked as a freelance journalist and propagandist, editing German Psychological Warfare for the Committee on National Morale, a private pre cursor to the OSS.
After world War II Farago worked for the UN-related diplomatic newsletter United Nations World, for Corps Diplomatique, and as a freelance journalist, eventually coming to join the staff of Radio Free Europe focused on supporting the brewing insurrection in Hungary in 1955-56 by developing a series of radio broadcasts featuring an apocryphal saboteur named Colonel Bell (Bell was subsequently identified by the Soviets as one of the contributors to the unrest that became the 1956 Revolution).
His most controversial book, Aftermath, reported on his research tracking down a wide range of Nazi war criminals as they fled Germany subsequent to the collapse of the Third Reich.
The British historian Stephen Dorril, in his MI6 Inside the Covert World of Her Majesty's Secret Intelligence Service asserts that Faragó was the 'most successful disinformer or dupe' concerning the presence of Nazis in South America.
The original text is as follows: Investigating 'The Nazi Menace in Argentina', author Ronald Newton found that the historic record had been left 'booby-trapped with an extraordinary number of hoaxes, forgeries, unanswered propaganda ploys and assorted dirty tricks'.
The most successful disinformer or dupe was the American Ladislas Faragó, 'a somewhat Hemingway-esque figure with a strong Hungarian accent and a confidential manner', whose 'good connections with the CIA and secret services of several European countries enabled him to investigate and publish on a non-attributable basis' a series of half correct tales.
[4] Moreover, French intelligence operative (during World War II - on the 'Resistance' side - and later) and conservative polemist Pierre de Villemarest justified[5] part of Faragó's statements.
