Indonesia, the world’s biggest Muslim-majority country, has a constitution that recognizes other major religions, and practices a syncretic form of Islam that draws on not just the faith’s tenets but local spiritual and cultural traditions. As a result, the nation has long been a voice of, and for, moderation in the Islamic world.
Yet Indonesia is not without its radical elements. Though most are on the fringe, they can add up to a significant number given Indonesia’s 260-million population. In the early 2000s, the country was terrorized by Jemaah Islamiyah (JI), a homegrown extremist organization allied with al-Qaeda. JI’s deadliest attack was the 2002 Bali bombing that killed 202 people. While JI has been neutralized, ISIS has claimed responsibility for recent, smaller terrorist incidents in the country and has inspired some Indonesians to fight in Syria — Indonesians who could pose a threat when they return home. The country has also seen the rise of hate groups that preach intolerance and violence against local religious and ethnic minorities, which include Shia and Ahmadiya Muslims.
