This chapter expands the analysis to the global stage, arguing that transnational radicalisation is intrinsically linked to the dynamics of imperialism and the uneven development inherent in global capitalism. It revitalizes Lenin’s theory of imperialism, showing how contemporary mechanisms of financialization and debt dependency function as a new form of colonial exploitation, locking the Global South into a subordinate position and creating profound anti-Western resentment. The chapter examines how the new international division of labor exploits a global reserve army of migrant workers, producing the deep-seated alienation upon which radical ideologies feed. The destabilizing role of the International Monetary Fund and World Bank is scrutinized, with their structural adjustment programs shown to have dismantled social safety nets and fueled conflict. A key focus is the role of digital technology, analyzing how social media platforms and encrypted apps have revolutionized extremist propaganda and organization, creating a digital infrastructure for transnational hate. The concept of “glocalization” is employed to explain how global extremist ideologies are adapted to local grievances, with case studies on ISIS in Syria and the far-right in Europe illustrating this dynamic fusion.
