Threats to human, national and international security as a result of biological warfare and pandemics are inadequately discussed in the popular media. Non-state actors are expected to use innovative methods to execute acts of terrorism. It is often contended that a terrorist organisation may well get the best results using conventional high explosives. This trend is clearly discernible in the methods used by terrorists worldwide. Manufacturing terror-grade dirty radiological or biological bombs that can be delivered effectively is far more difficult than using conventional explosives.
