David Danelo spent three months traveling the 1,952 miles that separate the United States and Mexico--a journey that took him across four states and two countries through a world of rivers and canals, mountains and deserts, highways and dirt roads, fences and border towns. Here the border isn't just an abstraction thrown around in political debates in Washington; it's a physical reality, infinitely more complex than most politicians believe. Danelo’s investigative report about a complex, longstanding debate that became a central issue of the 2016 presidential race examines the border in human terms through a cast of colorful characters. As topical today as it was when Danelo made his trek, this revised and updated edition asks and answers the core questions: Should we close the border? Is a fence or wall the answer? Is the U.S. government capable of fully securing the border?

In recent years, the south-western border of the United States has come under increasing pressure from the activities of Mexican narco-insurgents. These insurgents have developed rapidly from beginnings as nebulous gangs into networked cartels that have exposed the porosity of the border. These cartels declare no allegiance to any nation and are engaging in asymmetrical warfare against sovereign states throughout Mexico and in Central America. Within such states, de facto political control is shifting to the cartels in the ‘areas of impunity’ that have emerged. This book addresses these concerns and focuses on the criminal insurgencies being waged by the gangs and cartels. It is divided into sections on theory, Mexico, and the Americas and contains a number of introductory essays pertaining to this premier security threat to the United States and her allies in the region. Topics covered include criminal and spiritual insurgency, cartel weapons, corruption, feral cities, Los Zetas, politicized gangs, and threat analysis in Central America. This book will be a valuable resource to scholars in the fields of regional security, criminal justice and American Studies. It will be of great benefit to military and civil policymakers and practitioners in the areas of law enforcement and counternarcotics. This book was published as a special issue of Small Wars and Insurgencies.

"Peter Schrag is the model for all political writers. He is committed, passionate, and eloquent, but always stays harnessed to the facts and rooted in the realities of politics and human nature. He reports out everything, and he writes like a dream. We can be grateful that in Not Fit for Our Society he has turned his gifts to the seemingly intractable problem of immigration. We will have to settle this issue again, as we always manage to do despite enormous commotion and anxiety. Schrag will force everyone to think more clearly and to approach immigration with both compassion and good sense."_EJ Dionne, Jr., author of Souled Out "Just who is fit to be part of the society that became a nation in 1776 and who decides, and on what basis? In Not Fit for Our Society, Peter Schrag offers an invigorating, well-informed, carefully reasoned investigation into today's immigration debates."_David Hollinger, President of the Organization of American Historians, 2010-2011 "Peter Schrag has a unique view of the immigration debate and policies that have shaped our country since it's founding. His very timely writing of Not Fit for our Society helps us to better understand how the immigration debate and politics have gotten us to where we are today. His insights and intellect on the subject give all of us much to think about as we move forward on this very important issue."_Doris O. Matsui, Member of Congress "Peter Schrag has done it again. A sweeping review that puts the ferocity of our current immigration debate in historical context, Not Fit for Our Society is a must-read for those hoping to get past talk-show rhetoric and cherry-picked facts. Uncovering the dark impulses that have long undergirded nativist thought, he argues that we have seen this before_and that America will be better if we see through it again."_Manuel Pastor, University of Southern California "Peter Schrag offers a lively and thoughtful reinterpretation of America's ambivalence about immigration and immigrants' place in the nation's life. Drawing on his reading of primary sources and the latest scholarship, he tells a story rich in irony, detail, and nuance, tracing the history of nativism from the earliest days of the Republic to the current debates over immigration reform. The book is particularly striking for the way that it connects the arguments and organizations of the current anti-immigration movement to their roots in the eugenics movement and pseudo-scientific racism of the early 20th century."_Mark Paul, New America Foundation "[Schrag] delivers a story rich in irony, detail, and nuance, often told with passion and frequently challenging orthodoxies of both the political right and left. It is the right book at the right time."-Mark Paul, New America Foundation "History's lessons come through loud and clear as Peter Schrag vividly recounts the characters and the ideas behind that side of America that rejects immigration. Illuminating both in its sweep and its detail this 300-year narrative makes an important contribution to our understanding of today's policy debates."_Roberto Suro, author of Strangers Among US: Latino Lives in a Changing America "In an intemperate time, Peter Schrag's voice is lucid and truly American."_Richard Rodriguez
