This chapter explores the existing literature pertaining to Malaysia’s approach and its effect on terrorism. The chapter examines empirical evidences on the different terror-related incidents before and after programme implementation. The Malaysian government’s deradicalisation programme for terrorists can be considered successful. Multi-disciplinary threat assessment deradicalisation programmes should be implemented to identify individuals who may be exhibiting signs of radicalisation towards violent extremism. The ongoing terrorism threats and events around the globe have indicated that traditional hard, offensive security measures alone cannot stop and prevent acts of terror. With the outsized numbers of detainees imprisoned for security violations and terrorism, positive changes in their ideologies could alleviate future threats. In today’s security environment, extremism and radical ideology are issues that states cannot ignore and have resulted in more interest in developing deradicalisation programmes. The Malaysian government is enhancing its programme, continuously seeking creative ways to improve it.
