Originally,
blowback was
CIA internal coinage denoting the unintended, harmful consequences—to friendly populations and military forces—when a given weapon is used beyond its purpose as intended by the party supplying it. Examples include anti-Western religious figures (e.g.
Osama bin Laden) who, in due course, attack foe and sponsor; right-wing counter-revolutionaries who sell drugs to their sponsor’s civil populace (see
CIA and Contras cocaine trafficking in the US); and
banana republic juntas (see
Salvadoran Civil War) who kill American
reporters or
nuns (e.g.
Dorothy Kazel).[

In formal print usage, the term
blowback first appeared in the
Clandestine Service History—Overthrow of Premier Mossadeq of Iran—November 1952–August 1953, the CIA's internal history of the
1953 Iranian coup d'état, sponsored by the
US and
UK, which was published in March 1954.
[2][3] Blowback from this operation would indeed occur with the
Iranian Revolution and the
Iran hostage crisis.
