As the war in Ukraine enters its fourth year, this book critically examines the strategies employed by the European Union (EU) and the United States (US) in their support of Ukraine. It examines how sanctions, military aid, and diplomacy have shaped the conflict and considers whether these efforts are falling short. Through political, economic, and strategic analysis, it explores the EU’s internal divisions, the changing role of US leadership under a second Trump administration, and the increasing risk of Ukraine being marginalised in global negotiations. The author questions whether the EU’s reliance on sanctions and fragmented military support has weakened its own position more than that of Russia. Providing a realist perspective on the war’s broader geopolitical consequences and the uncertain future of European security, this book challenges dominant narratives.
