When Terrorism Goes to Sea: Terrorist Organizations and the Move to Maritime Targets

Terrorist groups are often relatively conservative in their choice of strategy, tactics, and targets, and it is worth asking what characteristics are associated with unconventional behavior. In this article we explore the question of why terrorist organizations move to one type of unconventional attack that has been a focus of concern of policymakers in recent years, namely attacks on maritime targets. Through an investigation of the organizational capacity and ideology of terrorist groups that committed maritime attacks between 1998 and 2005, we argue that this kind of violent behavior is driven by capability. Certain organizational characteristics of terrorist groups—territorial control, involvement in the drug trade, organizational size, and connections with other groups—provide groups with the capabilities that make maritime attacks both realistic and desirable. Terrorist groups' ideology—what they believe, and what their goals are—does not have the same impact, with the possible exception of groups affiliated with al-Qaeda. Our findings have implications for future research.
