Deter and defend

About Deter and Defend

NATO’s enduring aim is to safeguard the security of our one billion citizens, and to defend our shared values: democracy, freedom, and the international rules that promote peace and prevent war.

Today our defensive Alliance is facing complex challenges – assertive authoritarian regimes, terrorism, cyber and missile threats, climate change and disruptive technologies. In response, we are undertaking our largest adaptation since the Cold War, including the implementation of ‘The Concept for Deterrence and Defence of the Euro-Atlantic Area’, or more simply, ‘Deter and Defend.’
