This thesis examines characteristics of Islamic extremism in Nigeria. Specifically, the thesis examines the strategic indicators for an Islamic extremist safe haven and the presence of those indicators in Nigeria. The thesis includes four chapters beginning with a brief introduction, followed by a review of literature pertaining to global Islamic extremism ideology and Islam in Nigeria. The analysis chapter first establishes criteria from which to analyze the characteristics of a safe haven and then looks at how these indicators manifest themselves in Nigeria. The premise is that if these characteristics exist in any country or region, global Islamic extremist insurgents will use the country or region to promote its extremist ideology and promulgate activities conducive to the organization's goals. The fourth chapter makes recommendations to US planners on how to better characterize an Islamic extremist safe haven.
