This chapter examines how globalization has contributed to the growth of terrorism as a global phenomenon. It considers whether global terrorism is the price states pay for entry into and continued access to a globalized system, why violent Islamic extremism continues to be the primary motivator for global terrorist violence, and whether freedoms should be restricted to ensure greater security against the threat of global terrorism. The chapter first looks at the definitions of terrorism before tracing the transformation of terrorism from a transnational to a global phenomenon. It then explores the role of technology in terrorism and ways of combating terrorism. Two case studies are presented, one dealing with three generations of violent Islamic extremists and the other with the 2016 Lahore terrorist attack. There is also an Opposing Opinions box that asks whether states targeted by terrorism should aggressively address the threat beyond their national borders.
