TERRORISM AND ITS IMPLICATION ON GLOBAL SECURITY IN THE 21ST CENTURY (2010-2015)

This study investigates the evolution of terrorism and its implications on global security in the 21st century, with particular emphasis on the role of technology and social media in facilitating terrorist operations between 2010 and 2015. Anchored on the Frustration-Aggression Theory and Network Theory of Terrorism, the study explores the underlying causes, consequences, and international responses to terrorism within this period. Data were collected through ten semi-structured interviews and seven focus group discussions involving security experts, humanitarian workers, military personnel, and academics.Findings reveal that political instability, religious extremism, economic deprivation, porous borders, and technological advancements significantly contributed to the surge in global terrorism. Notably, terrorist groups such as ISIS and Boko Haram utilized digital platforms for radicalization, propaganda, recruitment, and coordination of attacks, amplifying their reach and impact. The consequences include mass displacement, destruction of infrastructure, loss of lives, economic disruptions, and weakened state institutions.The study recommends stronger international intelligence collaboration, proactive digital surveillance, humanitarian support for victims and displaced persons, and grassroots counter-radicalization programs. These measures, if adequately implemented, will contribute to reducing the influence and spread of terrorism globally.
