SOCIETAL POLARIZATION: AN EVOLVING THREAT TO U.S. HOMELAND SECURITY

Abstract

This thesis explores the context of escalating societal polarization and political violence in the United States, shedding light on their implications for homeland security. It poses the following research question: How does the social identity analytical method explain the rise of polarization and its attendant threats to homeland security in the United States? This study scrutinizes the role of social identities in shaping divisive perspectives and underscores the danger posed by polarization. The findings emphasize that polarization is not exclusively confined to differences in political beliefs but is intertwined with individuals’ sense of identity, where deeply held affiliations and self-perceptions become significant drivers of division. This phenomenon poses a significant challenge to national unity and security. In response to these challenges, the thesis concludes by advocating comprehensive reforms in education, media accountability, and evidence-based research. Further, it highlights the importance of exploring global polarization trends and addressing the intersectionality of identities. This research identifies the multifaceted challenges arising from polarization and linked violence, emphasizing the urgent need for collaborative efforts to preserve national security and cohesion in the United States.
