(Lessons Learned from the War in Ukraine)

Introduction

The Global and National Security Institute (GNSI) and JSS are pleased to present a special issue to our communities of practice on lessons learned from the war in Ukraine. This special issue brings together diverse perspectives on the lessons emerging from the Russia–Ukraine war, examining its military, political, economic, and societal dimensions. The articles explore NATO’s evolving deterrence posture, authoritarian alignments between Russia and its partners, Ukraine’s proxy strategies, and the future of warfare through kill-chain supremacy and artificial intelligence. The authors assess the performance of Russian electronic warfare, naval sea denial, and the staggering costs of unexploded ordnance, while also analyzing energy weaponization, EU energy transitions, and sanction evasion mechanisms. Beyond the battlefield, contributors investigate cognitive warfare, religious securitization, counterintelligence frameworks, and terrorism studies, offering a comprehensive view of how this conflict reshapes European security, global alignments, and the future of war itself.
