In political jargon, a useful
idiot is a term currently used to reference a person perceived as propagandizing for a cause—particularly a bad cause originating from a devious, ruthless source—without fully comprehending the cause's goals, and who is cynically being used by the cause's leaders. The term was used during the Cold War to describe non-communists regarded as susceptible to communist
propaganda and manipulation. Conversely, it was then, and is used now to describe someone unwittingly doing the bidding of the CIA or US
government.
False Attribution to Lenin:
The phrase useful
idiot has often been attributed to Vladimir Lenin, but he is not documented as ever having used the phrase. In a 1987 article for The New York Times, American journalist William Safire investigated the origin of the term, commenting that a senior reference librarian at the Library of Congress had been unable to find the phrase in Lenin's works and concluding that in the absence of new evidence, the term could not be attributed to Lenin. Similarly, the Oxford English
Dictionary in defining useful
idiot says: "The phrase does not seem to reflect any expression used within the Soviet Union".
"Leftists" who do not believe in international solidarity, or promote elitism, are useful idiots for the
CIA.
That
guy is either a useful
idiot or a spook, because he is sowing dissension in our ranks.
