The United States (U.S.) national strategy countering violent extremism (CVE) has yet to be updated and currently does not provide the necessary national framework to best combat self-radicalization and violent extremism (VE) in the United States. If people subscribe that the need for an updated strategy is evident, then the question is "What are the necessary and effective components of the national U.S. CVE strategy that best prevent self-radicalization and VE in the United States?" This research examined the concepts and strategies surrounding extremism and self-radicalization in the U.S., the United Kingdom (UK) and Australia. Through this analysis, multiple findings and recommendations were made. One such finding was the identification of overarching elements that, if implemented, would increase the effectiveness and applicability of the U.S. CVE strategy. These elements include: 1) identifying the federal agency in charge of administering the U.S. CVE strategy, 2) developing a more robust and actionable national CVE framework, 3) refocusing the federal government on support and not local engagement of CVE, 4) requiring all CVE related terms be defined in every document, and 5) requiring regular evaluations and updates of the U.S. CVE strategy. The details of these and other findings are contained in this book.
