Biological Attacks and the Non-State Actor: A Threat Assessment

In a climate of political concern about the deliberate dissemination of pathogenic micro-organisms, this article assesses the nature and scope of the threat to national security posed by actors other than states. Key factors include the motivations and disincentives for carrying out a biological attack and the technical challenges likely to be encountered by a non-state organization that decides to use disease as its weapon of choice. The assessment concludes that non-state organizations do not at present pose a great threat, that biological attacks should generally not be regarded as a ‘WMD’ issue, but also that the conduct of individual scientists engaged in pathogen research warrants careful monitoring.
