My case for pacifism, to recap, comes down to three simple premises. The first two are empirical:
Premise #1: The short-run costs of war are clearly awful. [Empirical claim about immediate effects of war].
Premise #2: The long-run benefits of war are highly uncertain. [Empirical claim about people’s ability to accurately forecast the long-run effects of war].
These empirical claims imply pacifism when combined with a bland moral premise:
Premise #3: For a war to be morally justified, the expected long-run benefits have to substantially exceed its short-run costs. [Moral claim, inspired by Judith Jarvis Thomson’s forced organ donation hypothetical].
