This paper considers the increasingly common suggestion that a new form of warfare has emerged. It clarifies the notion of new wars and responds to an argument for the claim that in order to achieve military parity non-state actors must violate just war principles. I reject the claim that violation of just war principles is necessary and argue that we can make reasonable normative judgments about new wars in terms of just war theory. From there, I consider the possibility that military parity can be achieved in a way that does not violate these principles and argue that it is permissible for relatively weak non-state actors to fight with fewer restrictions than conventional states.
