According to the 2025 Singapore Terrorism Threat Assessment, international extremist organizations and foreign conflicts continue to pose a serious threat. Singapore is a popular target because of its cosmopolitan identity and international connections. Recent cases conducted under the Internal Security Act (ISA) demonstrate the rise in self-radicalization, which is frequently fueled by online content. Young people are more vulnerable because of emotional tales and internet exposure. Because it makes it possible to create propaganda and facilitates attack planning, artificial intelligence has turned into a tool for terrorist activities. In order to reduce damage, the study emphasizes that combating terrorism is a shared responsibility and exhorts people to report suspicious activity right away.
