"Polarized Nations" explores the growing divide within modern societies, examining how political polarization manifests in different political systems around the world. From long-standing democracies to emerging authoritarian regimes, Jeremy Riley delves into the causes, consequences, and responses to political polarization across various systems of governance. Through a comparative lens, this book analyzes how social, economic, and technological forces—such as economic inequality, globalism, and the rise of social media—intensify divisions and shape the political landscape. Riley examines the historical roots of polarization in democratic systems like the United States and the United Kingdom, where deep ideological divides have become the norm, especially in the wake of economic crises and cultural shifts. The book also looks at how authoritarian regimes, such as those in Hungary and Russia, exploit polarization to consolidate power and suppress opposition. Additionally, the book draws from case studies in both established democracies and developing nations, shedding light on how polarization affects public policy, governance, and social cohesion. By tracing the evolution of political polarization across various contexts, "Polarized Nations" offers insight into the complex dynamics of political conflict and provides critical analysis of the ways in which polarized societies can either find paths toward resolution or descend into further fragmentation. Through this detailed analysis, Riley argues that understanding the intersection of political polarization, national identity, and global pressures is key to addressing the challenges facing modern political systems.
