Useful idiot – noun

A useful idiot is a derogatory term for a person perceived as propagandizing for a cause without fully comprehending the cause’s goals, and who is cynically used by the cause’s leaders.

The term was originally used during the Cold War to describe non-communists regarded as susceptible to communist propaganda and manipulation. The term has often been attributed to Vladimir Lenin, but this attribution is unsubstantiated.
