Abstract
This chapter considers how the adoption of autonomous weapons systems (AWS) may affect jus ad bellum principles of warfare. In particular, it focuses on the use of AWS in non-international armed conflicts (NIAC). Given the proliferation of NIAC, the development and use of AWS will most likely be attuned to this specific theater of war. As warfare waged by modernized liberal democracies (those most likely to develop and employ AWS at present) increasingly moves toward a model of individualized warfare, how, if at all, will the principles by which we measure the justness of the commencement of such hostilities be affected by the introduction of AWS, and how will such hostilities stack up to current legal agreements surrounding their more traditional engagement? This chapter claims that such considerations give us reason to question the moral and legal necessity of ad bellum proper authority.
