Experts warn that the Surabaya suicide attacks may be just a preview of what is to come, with extremist elements in Indonesia likely to regroup, support for Islamic State likely to continue and new alliances set to emerge. “The greatest impact [of the Surabaya attacks] on counterterrorism strategy was to force the hand of lawmakers to finally pass the updated legislation, which has provided greater powers of arrest, prosecution, and longer sentences,” says Mr Cameron Sumpter, an associate research fellow at the Centre of Excellence for National Security at the NTU in Singapore.
