Terrorism is a difficult to identify enemy of all societies. A world which does not fit into their ideology, encourages people to change the world. This can be achieved through political means, or move to a more suitable environment your ideology, or cause others to take your ideology on a gentle or malignant way. The latter we call terrorism, pressing your ideology on an anarchic way by using violence and disrupting society. Terrorists are often so convinced, that they see only one truth and are therefore difficult to influence by other ideologies. Terrorism is timeless. The attention of terrorism has grown the last years caused by international media and the worldwide penetration of internet. Disrupt society by spreading fear, by infiltrating communities by applying damage to the foundations of a state. This terrorism requires a different approach.
