History and usage

The term is purported to have been coined by Vladimir Lenin to describe those western reporters and travellers who would endorse the Soviet Union and its policies in the West. However, no reference to a communist sympathizer or political leftist as a "useful idiot" was made in the United States until 1948, and not until decades later would the phrase be attributed to Lenin. In 1948, the phrase was used in a New York Times article in relation to Italian politics, and was not mentioned again in print until 1961. The expression "useful idiot" has never been discovered in any published document of Lenin's, nor has anyone claimed to have heard him say it.

In the United States, the term is sometimes used as a pejorative by political conservatives against political liberals and radicals. The tone of usage implies that the "useful idiot" is ignorant of the facts to the extent that they end up unwittingly advancing an adverse cause that they might not otherwise support. The term gained increased use after the publication of conservative columnist and Reagan administration Mona Charen's 2004 book Useful Idiots: How Liberals Got It Wrong in the Cold War and Still Blame America First.

The term is also occasionally used by anarchists and some other radicals to describe groups and individuals whose ideology is alleged to be excessively deferential to a government or authoritarian political movement.

Since the September 11, 2001 attacks, the term "useful idiot" has also been used by some commentators to describe individuals said to take a softer line against Islamism and terrorism.

Para mí es un tópico de la propaganda anticomunista, ahora reciclada en propaganda antiislamista. Porque hay gente que siempre necesita estar en guerra con alguien.

Por cierto, en español se usa la expresión tonto útil.

Supongo que tienes una máquina que lee los pensamientos. También que conoces a muchos miembros del Komintern o afiliados al islamofascismo.

Claramente estás confundido, pero ¿de qué realidad hablas?
