Book excerpt: In the country’s changing threat environment, homegrown violent extremism (HVE) represents the next challenge in counterterrorism. Security and public policy expert Erroll Southers examines post-9/11 HVE – what it is, the conditions enabling its existence, and the community-based approaches that can reduce the risk of homegrown terrorism. Drawing on scholarly insight and more than three decades on the front lines of America’s security efforts, Southers challenges the misplaced counterterrorism focus on foreign individuals and communities. As Southers shows, there is no true profile of a terrorist. The book challenges how Americans think about terrorism, recruitment, and the homegrown threat. It contains essential information for communities, security practitioners, and policymakers on how violent extremists exploit vulnerabilities in their communities and offers approaches to put security theory into practice.
