"Talibanisation: Extremism and Regional Instability in South and Central Asia" is an in-depth study that explores the impact of Taliban-inspired extremism on the stability of both South and Central Asia. The work examines how the rise of the Taliban in Afghanistan has influenced political, social, and security dynamics across the region, with a focus on the spread of radical ideologies and the emergence of extremist groups. It also assesses the broader implications for regional cooperation, security, and the challenges faced by governments in addressing the dual threats of insurgency and ideological extremism, while considering the role of external actors in shaping the region's stability.
