With last Tuesday's horrific assault,"terrorism" has become the new American watchword and scourge. Yet as George Bush declares a war on terrorism," neither he nor anyone else has defined what terrorism is or where it comes from. Doing so may help us to face a frightening reality: the catastrophe of September 11 represents terrorism of a new, more challenging kind.Not all political violence, it should be specified, amounts to terrorism. Committed by stateless organizations against established powers, terrorism doesn't attack military centers to seize power, like guerrilla warfare. It specifically targets random, unsuspecting victims to publicize a grievance and sow panic among the strong.The word comes from the French Revolution's"Reign of Terror" (1793-94), when Robespierre's Jacobins executed 12,000 people deemed enemies of the Revolution, often for flimsy reasons. Since the Jacobins ran the state, we wouldn't call them terrorists today. Still, their vision of a violent purge in the name of Utopia provided a model for later insurgents.
