Abstract

The Russia-Ukraine War has reshaped Europe’s security landscape, leading to NATO’s most significant transformation since the Cold War. This study explores how the conflict has prompted NATO to realign its deterrence and defence strategies in response to Russia’s violations of international norms and changing battlefield dynamics. Employing a qualitative analysis of academic literature, official documents and credible reports, this study argues that NATO has shifted from assurance to a more assertive deterrence approach, enhancing its forward presence, increasing defence spending, and adopting effective new technologies. Key findings reveal important lessons about modern warfare, particularly the roles of artillery, unmanned systems, and air defence. The study also addresses the economic and energy repercussions of the conflict, noting how sanctions have reshaped global energy markets and accelerated European energy diversification. Ultimately, it concludes that NATO’s strategic shift represents a lasting change in European security, regardless of the conflict’s outcome.
