Bentley explains precisely why bioweapons are perceived as repulsive and how this sentiment is consequently expressed in the form of political behaviours, including the refusal to engage in biological aggression. Drawing on extensive archival evidence, this volume looks back on United States' foreign policy decision-making (particularly in relation to the Geneva Protocol and the Biological Weapons Convention) to demonstrate how and why the taboo has comprised a decisive factor in shaping both biowarfare strategy and political rhetoric - and why the taboo needs to be recognised as a necessary consideration in the study of bioweapons.

In analysing a taboo, the volume also takes the debate on international norms forward by questioning and challenging the wider analytic comprehension of 'taboo' itself. Rejecting current definitions of the concept as inadequate, Bentley proposes a new and original model of understanding based on the normative characteristics of disgust, stigmatization, and fetishization.
