Book excerpt: This original and timely book is the first to analyze the interconnectedness of migration, regional integration and the new security studies. Exploring the conflict between the actions of transnational migrants and state government policy in a series of theoretical chapters and regional case-studies, the book includes theoretical chapters which look at three key facets of the nation-state: population, territory and government, discussing the ways in which migration, regional integration and new security thinking challenge the accepted role and responsibilities of the state. Regional case-studies are also included which explore the specific challenges faced in regions including Central America, Asia and the Pacific and Central and Eastern Europe. As a book that asks crucial questions about the formulation of migration policies and the consequences of that success of failure, it will be essential reading for students and scholars of migration in sociology, politics and international relations and also for those with professional interests in the area.
