In yesteryears, my preceding and precursory work on intelligence analysis, operations and international cooperation received different pieces of information, cannonball and notices, which inculcated me to paint a different picture of security and law enforcement mechanisms in Europe. This book highlights different types of political and social transformations in the EU. No doubt, I received precarious threats in case of written letters and telephone calls, but I never relinquished my academic and intellectual struggle against the sarcastic forces. Over the past 20 years, EU intelligence infrastructures lived through numerous management crises and ordeals. France has entered a political, social and economic transformation phase. In France, the focus of Jihadist groups has been radicalization of the young generation since 2001, but it is unclear how many foreign fighters have ultimately claimed asylum in France, and under what objectives. Before the rise of ISIS, African and South Asian jihadist groups were operating in France to expand their terrorist networks. With the presence of Jihadist Groups and the ISIS members in France, the use of chemical, biological and nuclear weapons cannot be ruled out, the fact is, that the ISIS found these weapons in Iraq. Material of Dirty Bomb, biological and nuclear weapons material can be purchased from black market of India and Pakistan. There are possibilities that terrorists can acquire nuclear material or a complete warhead to use it against their targets. The risk of a complete nuclear device falling into the hands of terrorists will cause consternation in the EU. The abrupt outburst in towns and cities of France was a great lesson for all European states that managing a better law and order can be laborious without introducing security sector reforms. As we have seen in yesteryears, terrorist and extremist groups made access to nuclear sites and recruited a good number of European citizens in order to use them for jihad in Europe. From the Yellow Vest movement to the recent terrorism (riots) incidents, extremist forces had designed to take control of government installations, cities and towns in order to further strengthen their networks. In all these and other events, French intelligence exhibited its professional approach and proved that a strong and reformed secret agency can better manage national security crises.
