Abstract
This is a short introduction by the two authors Rada Iveković and Ranabir Samaddar to the issue of the French journal "Rue Descartes" (N. 62), titled "Terrors and terrorisms" or, in French "Terreurs et terrorismes". They start from the idea that what is called "terrorism" isn't in itself an independent phenomenon, but is rather historically produced and then fought by the state as well as by the international system of states, in a vicious circle that radicalises positions and violence. But "terrorism" (or "terror") is nothing in itself, its definition is extremely vague, and it turns around the state and its power.
