What can terror mean from a conceptual point of view? What does it mean for people? Do populations feel it? Is terror the same as fear? Has Europe always been under a cloak of terror? Is there a feeling of terror even during periods of “peace”? Causes, characteristics, permanencies, changes, consequences, overcoming trauma, post-war coexistence, resilience, solidarity, legal implications in terms of human rights, mass mobilization for a culture of peace are the main issues focused on this topic. When the questions are more than the answers, we believe we are going on the right path.
