While much attention has been focused on the Islamic State threat to Europe, the increasingly fertile ground for jihadi expansion in Southeast Asia means the Islamic State may pose as big a future threat to the East as the West. Islamic State operatives inside Syria and Iraq have leveraged existing local networks in Southeast Asian countries to remotely enable terrorist plots in their home countries, and there is concern that foreign fighters, and not simply Southeast Asian returnees, will export terrorism to the region as the Islamic State suffers setbacks in Syria and Iraq. These threat trends may accelerate if the Islamic State declares a wilaya in parts of Southeast Asia where extremist groups already enjoy safe havens, creating a potential magnet for foreign fighters.
