The first reference to provide a comprehensive overview of how al-Qaeda and other terrorist groups have impacted the way nations protect their borders, this book examines border security organizations and discusses the goods and people that cross national perimeters. Each chapter provides a review of each nation's border security, a discussion of the impact of changes in security, the steps taken to protect the country, and an assessment of whether or not the al-Qaeda threat has contributed to those changes. Countries covered in the text include the US, Canada, UK, France, Germany, Italy, Australia, Austria, and Iran.
