 Narrow definitions are revisionary, but (unlike those discussed in the next section) not implausibly so. They focus on the traits of terrorism that cause most of us to view the practice with deep moral repugnance: (i) violence (ii) against non-combatants (or, alternatively, against innocent people) for the sake of (iii) intimidation (and, on some definitions, (iv) coercion). In highlighting (ii), they relate the issue of terrorism to the ethics of war and one of the fundamental principles of just war theory, that of non-combatant immunity. They help distinguish terrorism from acts of war proper and political assassination, which do not target non-combatants or common citizens. It does not matter very much whether the victims of terrorism are described as “non-combatants” or “innocent people”, as each term is used in a technical sense, and both refer to those who have not lost their immunity against lethal or other extreme violence by being directly involved in, or highly responsible for, (what terrorists consider) insufferable injustice or oppression. In war, these are innocent civilians; in a violent conflict that falls short of war, these are common citizens.
