'In the 21st century, border security across most of the world is not about deterring military invaders but rather transnational law evaders, ranging from drug smugglers to arms traffickers to terrorists. Arie Kacowicz and his colleagues have written an ambitious and sweeping cross-regional account of recent border transformations, with case studies covering all corners of the globe. Far from receding in a globalizing world, border anxieties are actually intensifying. This timely book will be of great interest to both scholars and practitioners trying to make sense of today's border security landscape.'
