The threat of chemical and biological terrorism emanating from non-state actors, including the Islamic Jihadi organisations, which control large swathes of territories and resources, remains a major concern for nation states today. Over the years, the capability and intentions of Islamic jihadist groups have changed. They evidently prefer for more destructive and spectacular methods. This can be very well argued that if these weapons systems, materials or technologies were made available to them, they probably would use it against their enemy to maximize the impact and fear factor. Even though no terrorist group, including the Al Qaeda, so far has achieved success in employing these destructive and disruptive weapons systems or materials, in reality, various terrorist groups have been seeking to acquire WMD (Weapons of Mass Destruction/Disruption) materials and its know-how.
