Russia’s ‘Plausible Deniability’ Comes to an End

Every hybrid war depends on a central idea: “plausible deniability.” A state can deny responsibility for an attack when no formal proof exists, even when the evidence points in its direction.

That uncertainty is not a weakness. It creates doubt, confusion and fear among opponents while making a broadly accepted response difficult. The absence of a clear signature can strengthen the effect of such operations.

But that shield has now fallen, the commentary argues. Germany has officially held Russia under Vladimir Putin responsible for an attempted attack involving an explosive-laden drone at Leipzig airport.

The accusation removes what had served as a small fig leaf for Moscow as dozens of actions, explosions, acts of sabotage, cyberattacks and disinformation campaigns hit European countries. The countries mentioned include Germany, Romania, France, Finland and the United Kingdom.

The piece presents Germany’s accusation as a moment when Russia’s alleged hybrid warfare activity can no longer rely on the same degree of uncertainty over responsibility.
