The term is used both to describe conscious agents operating under the control of an intelligence service and political opponents who may be classed as a "useful idiot" that is, someone, completely unaware of how their actions further the interests of a foreign power.
A related concept is that of a front organization
Critics have argued that the term can be applied to anyone whose political views are disliked by the user.[2]
Criticism[edit]
Criticising the concept, John Girling writes[2]
'Agents of Influence'is an intriguing conception, whose meaning
is as mysterious as its origins, and whose attribution reflects as
much on the user as on the 'used*. With its vague and rather
sinister undertones of manipulation and deceit such a hybrid
expression lends itself easily to innuendo and abuse. It is not
surprising, therefore, that the prejudiced or the merely careless
should characterise those whose political views they dislike, not
as agents of a foreign power (for the allegation lacks any concrete
proof), but as 'agents of influence' working *wittingly or unwittingly*
either for the American CIA or the Soviet KGB
