A string of high-profile attacks in Paris, Istanbul, Jakarta and Brussels in the past five months has left little doubt that the Islamic State in Iraq and Syria (ISIS) poses real danger to people everywhere.

Singaporeans are no exception.

In those attacks, the terrorist group has shown a high degree of sophistication and planning. Bombs were set off in a coordinated manner to inflict maximum casualties and sow widespread panic. ISIS today poses a far graver threat than its predecessor Al-Qaeda ever did, Home Affairs Minister K. Shanmugam said in Parliament earlier this month.

As devastating as suicide bombings and shootings are, they represent the conclusion of a journey that begins with radicalisation.

… Already, more than 30 militant groups from South-east Asia, mostly from Indonesia, have pledged allegiance or expressed their support for ISIS, said regional terrorism expert Rohan Gunaratna.

… Singapore is well known for its uncompromising stance against terrorism, its participation in the global coalition against ISIS, and its efforts to combat terrorism in South-east Asia. That it has been spared attacks is not for lack of trying by the terrorists, said analyst Jasminder Singh of the International Centre for Political Violence and Terrorism Research.
