Can Terrorism Ever Be Morally Justified?

This paper provides a framework to make moral sense of terrorism. The framework consists in a test, referred to as the MODAL test, which is an acronym standing for five tests or principles for determining the moral defensibility or indefensibility of terrorism. The five principles concern the motives for terrorism, its objectives, destructiveness, availability of alternatives, and likelihood of success. This approach makes it conceivable but highly unlikely in practice that a terrorist act is morally justified. The MODAL test does not claim to be an exhaustive framework for analysing the moral legitimacy or illegitimacy of terrorism but rather a practical analytical tool aimed at securing a reliable grasp of the tricky question of the relation between morality and terrorism.
