The normative approach to defining an ethic of a field, which focuses on one disciplinary field, requires modification in the consideration of a biodefense ethic to include not one discipline, but many. The consideration of an ethic in biodefense must capture issues in a multidisciplinary scope, including the ethical studies in the disciplines of medicine, sciences, technology, law, international relations, public health, environment, and war, each having their unique framework of ethical constructs.An ethic of bioterrorism and biodefense raises issues which (...) can be examined utilizing multidisciplinary ethical considerations. The disciplines of medicine, sciences, technology, law, international relations, public health, environment, and war each have a framework of ethical principles which are essential in the scope of ethics which are incident to bioterrorism and biodefense; the absence of any one of which would create a void in our understanding of the complexity of this subject.
