Blowback (intelligence)

Blowback is the unintended consequences and unwanted side-effects of a covert operation. To the civilians suffering the blowback of covert operations, the effect typically manifests itself as "random" acts of political violence without a discernible, direct cause; because the public—in whose name the intelligence agency acted—are unaware of the effected secret attacks that provoked revenge (counter-attack) against them.
