ABSTRACT
Nuclear and other weapons of mass destruction (WMD) will be a part of our world for the foreseeable future. This chapter will concern itself with questions that arise from the possession and potential use of WMD. I will first examine the possibility of a WMD use that is both proportionate and indiscriminate, then look at three likely scenarios in which the use of WMD may be justifiable: to destroy WMD arsenals, particularly biological and chemical weapons, to destroy deeply buried targets which are impervious to conventional attack, and to deny ultimate victory to an adversary. I will also consider the need to have all WMD use conform to the jus post bellum and the continuing debate about just nuclear deterrence.
