Since September 11 2001, the US government has focused its energy and defensive capabilities on countering the spread of Islamic radical extremists and their brand of terrorism. Over the last 15 years of continued engagement in this effort, policymakers have learned many lessons. Most importantly, the Global War on Terrorism requires a multifaceted approach to undermine the ideology of radical extremists rather than merely applying kinetic action against physical targets. This radicalization -- the demand for the overthrow of state governments --derives from an ideology used in recruiting, motivating and validating terrorist activities.
