Terrorism, jus post bellum and the Prospect of Peace

Just war scholars are increasingly focusing on the importance of jus post bellum – justice after war – for the legitimacy of military campaigns. Should something akin to jus post bellum standards apply to terrorist campaigns? Assuming that at least some terrorist actors pursue legitimate goals or just causes, do such actors have greater difficulty satisfying the prospect-of-success criterion of Just War Theory than military actors? Further, may the use of the terrorist method as such – state or non-state – jeopardize lasting peace in a way that other violent, for instance military, strategies do not? I will argue that there appears to be little reason to believe that terrorist campaigns are in principle less able to secure or at least contribute to a lasting peace than military campaigns; quite to the contrary. Or, put differently, if terrorism is an unlikely method for securing peace, then war is an even more unlikely one.
