| Outline of Final Research Achievements |
This study has examined and clarified the conditions of the right of self-defence, especially the necessity and proportionality requirements in the use of force against terrirists or non-state actors. As international humanitarian law has developed through the interchange of benefits of states as well as the interest of humanity, non-state actors do not seem to have the incentives for complying with international humanitarian law. Based on this difficult legal situation from the perspective of the method of warfare in Jus in bello, this study tried to challenge the traditional sharp distinction between the jus in bello and the jus ad bellum with the close examination of related judgments of ICJ and other state practices. It follows that jus ad bellum thorough the necessity and proportionality principles is likely to be applicable and functions in the impediment to enforcement of international humanitarian law against non-state actors in order to regulate the use of force effectively.
