South-East Asia came into prominence in the global war against terrorism following the seminal terrorist attacks in the USA on 11 September 2001. The presence of other radical groups and networks other than the Jemaah Islamiyah (JI) indicates that the problem of radical Islamist terrorism is much wider and broader than the JI. With the assistance of Australian police and forensics, the Indonesian security services quickly tracked down and arrested a number of suspected JI operatives. The JI has carried out a series of terrorist attacks in Indonesia, beginning with the deadly Bali bombing in October 2002. A hiatus in terrorist attacks followed, as Indonesian counter-terrorism police scored a number of successes, eliminating a significant number of JI operatives throughout the country, thus enabling Indonesia to enjoy a four-year respite from major terrorist attacks. Despite the successes of counter-terrorism operations in Indonesia, there is increasing realization that the radical problem is much broader than the JI.
