Biological warfare is not a new concept in arena of international politics as it has been used as a tool to sabotage enemy in previous centuries. Biological weapons are a sub-category of Weapons of Mass destruction (WMDs) in which there is a deliberate use of micro-organisms like pathogens and toxins to cause disease or death in humans, livestock and yields.Form its usage in 14th century by Mongols to its usage by imperial Japan during 1930s-40s against Chinese, it has always been a threat to global security. The evolution of bio-weapons can be broadly categorized into four phases; first phase includes the post WWII developments with the evident use of chlorine and phosgene in Ypres.The second phase was marked by the use of nerve agents like tabun, cholinesterase inhibitor and anthrax and plague bombs. The initiation of third phase was marked by the use of biological weapons in Vietnam war during 1970s where deadly agents like Agent orange were used. 4th and last phase include the time of biological and technological revolution where genetic engineering techniques were at their peak. Traditionally they have been used in wartime in order to defeat enemy but with the emergence of violent non-state actors, bioterrorism is another potential threat to the security of states. There are certain goals that are associated with the use of biological weapons. Firstly, it is purposed to hit to economy of the targeted country, breaking down government authority and have a psychological effect on masses of the targeted population. It is also a kind of psychological warfare as it may hit a smaller number of people but leaves impact on wider audience through intimidation and spreading fear. It also creates natural circumstances under which a population is induced with disease without revealing the actual perpetrator.
With the advancement in genetic engineering techniques more lethal biological weapons are being produced everyday around the world. Countries which are economically deprived are more likely to pursue such goals as it is difficult for them to go for heavy military sophistication keeping into consideration their poor economic conditions. Biological weapons serve as inexpensive tool for developing countries to address their issues in prevailing international security environment. During the initial decades of cold war, united states of America (USA) and Soviet Union went for acquiring tons of biological weapons alongside nuclear proliferation.
The quest for these weapons reduced during 1970s with the formation of Biological and Toxin Weapons Convention (BWC). This convention was presented in 1972 before countries and finally came into force in 1975 with 150 countries who signed this convention and 140 countries who fully joined this treaty. This convention prohibits any biological weaponization in order to promote peace and stability around the world. But this convention has obvious defects as it is unable to address many issues like it doesn’t prevents itself the use of biological weapons but just reinforces 1925 Geneva Protocol which forbids the use of bio-weapons. Convention allows ‘defensive research’ to which there are many objections that what is incorporated into this defensive research. It is non-binding to the signatory states and in case if countries are proliferating it lacks the effective oversight techniques to look after them either they are pursuing these biological weapons capabilities or not. Since the inception of this convention till now it has clearly failed in stopping the countries from acquisition as well as usage of these weapons. This is evident as there were many cases after 1975 where these weapons were used as in 1980s when Iraq used mustard gas, sarin and tabun against Iran and many other ethnic groups inside Iran. Another incident which was highlighted was Sarine nerve gas attack in Tokyo subway system leaving thousands injured and many got killed. In post-cold war era, however, the number of these attacks reduced as much attention was shifted to terrorism after 9/11 attacks with the change in global security architecture.
“Anthrax letters” in post 9/11 attacks revealed yet another dimension of bio-weapons which was the threat of bioterrorism from non-state actors. US became a victim of bio-terrorism when in 2001 a powder was transported through letters containing bacterium called anthrax infecting many people. One purpose which terrorists have is to make general masses feel as if they are unsafe in the hands of their government which can be best achieved through the use of these weapons. The fact that biological weapons are cheaper and more devastating than conventional weapons make it more likely for biological weapons to be used by terrorists. Also, the fact that they are easy to hide and transport and a smaller quantity can leave long-lasting impacts on larger population makes these weapons more appealing. Now that we are facing a global pandemic in the form of COVID-19 which according to some conspiracy theories is a biological weapon pose even more serious challenge to the international security in coming decades. There is no such scientific research which proves Corona Virus as a biological weapon but the realization here is that whether or not it is a biological weapon but world was least prepared for it. Not only the developing countries but also developed states suffered more despite having enormous medical infrastructure. The fact that there has been decline in the incidents related to bioterrorism should never let us think that there is no possibility of such attacks. The fact that world failed to handle Covid-19 puts a question mark on the credibility of measures if we are faced with bio-terrorism. The medical community as well as general population needs to develop an understanding of how to respond if there is such attack. At the international level there is a dire need to develop some strong norms which discourage the development and use of such weapons in any capacity.
