In this changing world, a massive, mutative, asymmetrical and Islamized terrorism has gradually been implanted: the radical Islamist threat, illustrated notably by the Al-Qaeda nebula, figurehead of Jihadism and today rivaled by African groups recently created such as Boko Haram (Pérouse de Montclos, 2012 ; Guibaud 2014 ; Kongou, 2014 ; Saibou, 2014 ; Pommerolle, 2015).This transnational phenomenon henceforth at the heart of socio-political life of Cameroon is challenging in many ways. Our analysis focuses on this new belligerent dynamics which is linked to the sovereignty of states and to the international political games. This will help us understand the variations of a flap of assaults perpetrated by this Islamic sect. Through an analysis of the actors and their instruments, this paper highlights the paradigm of international policy making.
