In sum, this anthology represents some of the best and brightest scholars of today who are writing on the evolving security environment in Mexico and the implications this may hold for the United States. They have greatly enhanced our understanding of crime wars and criminal insurgencies-21st century war and conflict waged by non-state entities- and the impact this new form of warfare is having on states. For this, we embrace them and have established the new SWJ El Centro forum to further promote their professionalism and scholarship.Dave DileggeSWJ Editor-in-Chief
