About this report
In Europe’s strategic discourse, proportionality has become the default reference point whenever the issue of responses to threats and aggressions is raised. Whether the subject is terrorism, cyberattacks, or hostile actions by rival powers, the formula is almost ritual: a proportionate response, calibrated, commensurate to the damage suffered.
This approach, seemingly balanced and consistent with international law, hides a structural weakness: Europe has lost the ability to speak the true language of deterrence. Deterrence is not, and has never been, a mechanism of symmetry.
Key questions this report answers
- Why has proportionality become Europe's default reference point in responding to terrorism, cyberattacks and hostile actions by rival powers?
- What structural weakness does the ritual of a 'proportionate, calibrated' response conceal in European strategic discourse?
- Why has Europe lost the ability to speak the true language of deterrence, and why is deterrence not a mechanism of symmetry?
- What are the strategic implications of recovering the forgotten language of deterrence for European security?
Who it's for
