This book analyses the attacks carried out by Al Qaeda and the Islamic State in Western Europe, and especially in the countries that have been hardest hit by jihadist terrorism and where the State Security Forces and Corps have carried out the most operations against this type of terrorism. It also details the ideological sources of the leaders of the global jihadist movement, of their struggle for leadership in the world and within the jihadist movement, their financing, and the dissemination of their message through the media and social networks. The book explores the radicalisation of those individuals who, attracted by their cause, approach these organisations offline and online, as well as the radicalisation of European fighters who have gone to Syria and Iraq to wage jihad and help consolidate the caliphate. It will appeal to historians, journalists, jurists and the general public.
