This book examines the political, diplomatic, and financial responses to the Russo-Ukraine War through the lens of Realist international relations theory. Analyzing the origins and ongoing dynamics of the conflict, the book sheds light on how the West - especially the EU and NATO - has reacted to the war and discusses the implications of its strategy. It critically explores the influence of national populism and internal disunity within the West, particularly against the background of rising Trumpism.The book offers a fresh perspective on the geopolitical shifts reshaping power dynamics and traditional international relations. From Ukraine's military struggles to NATO’s challenges, it analyzes how the conflict has disrupted existing political norms. The book makes a case for rethinking the global political framework as the war continues to evolve and will appeal to students, scholars, and researchers of international relations and geopolitics.  “This book offers a timely analysis of the Russo-Ukraine War and its transformative impact on global geopolitics. Examining the conflict's origins, strategies, and broader implications provides essential insights into shifting international dynamics and challenges to traditional geopolitical paradigms, making it an invaluable resource for understanding the current crisis and evolving frameworks of global relations.”Lisheng Dong, Emeritus Professor at the University of Tartu and former Visiting Professor at the University of Zurich “The West’s Response to the Ukraine War is a bravura performance.
