ABSTRACT
Does the just-war tradition (JWT) apply to cyberwarfare (CW)? I attempt to answer that question in several ways: in the first section below by rejecting the peculiar logic that says the JWT doesn't apply because CW is not really war; then by offering a positive case for the JWT's relevance to CW; and third, by showing that scenarios dubbed "hard cases" involving responses to conventional and cyber attacks conform nicely to long-established JW principles. In the fourth and final section below I suggest ways in which CW might pose special challenges to JW analysis. I conclude that CW's moral and logical ambiguities, though somewhat new, present differences of degree rather than kind; analogously ambiguous cases have long existed in warfare without undercutting the JWT's broad relevance.
