Abstract
Defining "terrorism" as the intentional targeting of non-combatant civilians, the paper argues that, other things being equal, it is not possible to effectively distinguish morally between "terrorism" and use of military power against combatant targets which might reasonably be expected to produce some guesstimable quantity of "collateral" or non-combatant civilian casualties; that it is upon the expected likely consequences of actions rather than upon the intentions underlying them, that actors should be morally judged. Furthermore I argue that other attempts to rationalize the use of conventional military force, as retaliatory for prior "terrorist" actions, or as preemptive, also often largely fail either on historical grounds or pragmatic grounds.
