Combating „maritime terrorism“ off the coast of Somalia

This paper evaluates the effectiveness of the international naval mission in the Gulf of Aden from 2008-2010, both in terms of its counter-piracy and its counter-terrorism objectives. We draw on arguments developed in the literature of law and economics, detailed statistical analyses and a large number of in depth interviews. Counter-piracy operations are a qualified success: their main effects are the stabilisation of attacks at a high level and the substitution between the relatively well protected transit corridor in the Gulf of Aden and the open sea. However, the counter-piracy measures appear to deter pirates from forming alliances with Islamist movements and may therefore make a major contribution to international security. -- Piracy ; Somalia ; counter-terrorism ; law and economics ; deterrence ; naval intervention
