NATO Approaches to Forward Defence and Contemporary Deterrence and Defence Adaptation

Russia’s large-scale war against Ukraine was a wake-up call for the entire international community and, in particular, for NATO Alliance. It became obvious that Europe is no longer at peace, and that serious steps should be taken by the Transatlantic collective defence Alliance. NATO intensified the adaptation of its deterrence and defence posture. The 2022 NATO Madrid Summit marked a major shift in NATO’s deterrence and defence posture, and it was agreed to transition from defence by reinforcement to forward defence. The article discusses the concept of forward defence, its historical evolution and its practical implementation by NATO. It evaluates forward defence in relation to defence and deterrence strategies that existed during the Cold War and how they have changed over the time. It examines how forward defence contributes to the doctrinal conventional deterrence and defence principles and indicates major changes in collective defence. It debates whether and how NATO is experiencing a real paradigm shift in its doctrinal deterrence and defence perception and how forward defence can help ensure that every inch of the Allied territory is defended.
