ABSTRACT
Russia’s full-scale war in Ukraine has reshaped the strategic environment in Europe and compelled NATO to reassess its defence posture, internal cohesion, and long-term credibility. This paper provides a comprehensive evaluation of the Alliance’s evolving power dynamics, focusing on the distribution of military capabilities among its principal actors, the potential consequences of U.S. strategic retrenchment, and the implications of Russia’s wartime adaptation. While NATO retains substantial aggregate superiority, persistent disparities in defence spending, divergent national threat perceptions, and Europe’s structural dependence on U.S. leadership continue to challenge the Alliance’s resilience. At the same time, Russia’s simultaneous military degradation and accelerated defence-industrial mobilisation create a paradoxical trajectory in which significant battlefield losses coexist with rapid technological innovation, deeper partnerships with China, Iran, and North Korea, and the growing integration of unmanned and long-range strike systems. The study further analyses how the widespread use of drones and low-cost precision technologies has altered the cost-exchange ratios in modern conflict, exposing critical vulnerabilities in NATO’s air and missile defence architectures. Incidents such as Russia’s 2025 drone incursion into Polish airspace illustrate the increasing mismatch between inexpensive offensive systems and the costly defensive measures required to counter them. Drawing on comparative data, doctrinal analysis, and scenario-based reasoning, the paper argues that NATO’s future effectiveness will depend not only on aggregate strength but on its capacity to adapt doctrinally, industrially, and technologically. The findings underscore the need for accelerated European defence-industrial revitalisation, more equitable burden-sharing, and the incorporation of unmanned and autonomous systems into NATO’s integrated deterrence and defence planning.
