Focuses on a small but important group of movements that constitute a distinct 'fifth wave' of modern terrorism, called the "New Tribalism". This book critiques David Rapoport's Four Waves theory, arguing that the theory does not account for movements which radicalize and turn inward, losing touch with, or interest in, their foreign compatriots.
