IntroductionA United States citizen turning against his or her government and espousing an ideology to kill another citizen or commit an act of violence is a growing phenomenon commonly known as homegrown terrorism. This process of transition or radicalization that transforms an individual into an adversary has intensified since the September 11, 2001 attacks on the World Trade Center and the Pentagon. The problem continues to persist in other parts of the world such as Canada, the United Kingdom, and even Saudi Arabia, a non-Western country. This form of extremism has shown its propensity in the United States since the turn of the century, when Muslim extremism had its first beginnings as a venue for supporting a black separatist movement. Today, the threat emerges more pervasively with the accessibility and excess of information technology; as well as the political and socio-economic environment that influences many spectrums of perception and intent. Brian Jenkins, a senior consultant at the Rand Corporation, a political research think tank organization, defines radicalization as the "process of adopting oneself or inculcating in others a commitment not just to a belief system, but to their imposition on the rest of society” (Gartenstein-Ross and Grossman, 2009, p. 7) describe radicalization as “changes in beliefs, feelings, and behaviors in directions that increasingly justify intergroup violence.” and require sacrifice in defense of the in-group” (p.416). In the context of radicalization, an individual discovers a new revelation about how he or she perceives the world. Radicalization does not happen suddenly but is a complicated process influenced by experiences personal, from the environment, from the character of the personality... half of the document... The action associated with peace and tranquility has a long history of violence. Mark Juergensmeyer in his book Terror in the Mind of God, stated that religion provides the ideological resources for an alternative vision of public order (Juergensmeyer, 2003). This supports the previous definition stated earlier by Brian Jenkins who emphasized that radicalization means imposing one's beliefs on society (Gartenstein-Ross and Grossman, 2009). Juergensmeyer further stated that all religions are inherently revolutionary and have elements of public violence to support their justification in the name of God and a higher being (Jergenmeyer, 2003). Understanding the motivations, reasoning and influences of the radicalization process will help mitigate religious violence and identify a proactive approach to preventing conversion to terrorism at home..
