Revisiting plausible deniability

Pages 511-533 | Published online: 02 Mar 2020
 

ABSTRACT

Despite its prominence as a tool of statecraft, covert action’s defining characteristic – plausible deniability – remains a slippery concept. This article investigates the logics underlying the two main variants. The first ideal-type, the state model, captures efforts by states to disclaim sponsorship of covert operations. The drivers of covert action are primarily international, the sources of exposure are many, and its relationship with democratic norms is harmonious. The second ideal-type, the executive model, describes efforts to shield chief executives from blame. The drivers of covert action are domestic, the sources of exposure are limited, and its relationship with democracy is conflictual.

8 Although they differ in the sense that the Bay of Pigs was a CIA-led operation whereas Iran-Contra was not, they both qualify as covert action according to conventional definitions. Moreover, the fact that one of them – Iran-Contra – was conducted outside of established channels illustrates the logic of the executive model. That is, leaders may go this route when conducting covert action to escape culpability.
