This book examines the role of terrorist innovation and learning in theory and practice, within the context of three specific EU case-studies.

The starting point for this book was twofold; first, to examine the issue of innovation and learning more generically both in theory, within specific themes, and within the context of al-Qaeda’s influence on this process; second, this book examines the evolution of specific al-Qaeda-related plots in three specific northern EU states – the United Kingdom, Denmark and Germany – where there has been a significant volume of planned, failed and executed terrorist plots. In particular, these case studies explore signs of innovation and learning.
