This book examines Kazakhstan’s political, economic, social, ideological, and security response to Russia’s 2022 invasion of Ukraine, exploring its impact on international relations and Kazakhstan’s resulting precarious position. Economically, strategically, and culturally linked to the Russian Federation, Kazakhstan, in the aftermath of the invasion, has sought to balance containing Russia’s threats and potential invasion, strengthening regional stability, and defending its national interests. This book expands readers’ knowledge of Kazakhstan’s internal and foreign politics, exploring how the country navigates its reintegration and strategic partnership with Russia while maintaining its obligations to international law and fostering goodwill with European and American partners. Kazakhstan as a Middle Power in Wartime is essential reading for scholars and students of international relations, political science, and contemporary conflict, particularly those with an interest in Russia, Eastern Europe, and Central Asia.
