"In August 2011, the Obama Administration announced its counter-radicalization strategy. It is devised to address the forces that influence some people living in the United States to acquire and hold radical or extremist beliefs that may eventually compel them to commit terrorism. This is the first such strategy for the federal government, which calls this effort 'combating violent extremism' (CVE). Since the Al Qaeda attacks of September 11, 2001, the U.S. government has prosecuted hundreds of individuals on terrorism charges. Unlike the necessarily 'secretive' law enforcement and intelligence efforts driving these investigations, the CVE strategy includes sizeable government activity within the 'open marketplace of ideas,' where private citizens are free to weigh competing ideologies and engage in constitutionally protected speech and expression. Some of the key challenges in the implementation of the CVE strategy likely spring from the interplay between the marketplace of ideas and the secretive realm encompassing law enforcement investigations and terrorist plotting. The strategy addresses the radicalization of all types of potential terrorists in the United States but focuses on those inspired by Al Qaeda. To further elaborate this strategy, in December 2011 the Administration released its 'Strategic Implementation Plan for Empowering Local Partners to Prevent Violent Extremism in the United States' (SIP). The SIP is a large-scale planning document with three major objectives and numerous future activities and efforts. The SIP's three objectives involve (1) enhancing federal community engagement efforts related to CVE, (2) developing greater government and law enforcement expertise for preventing violent extremism, and (3) countering violent extremist propaganda."
