A translation of Girish Kuber's Yuddha Jivanche, this book explores the history of biological and chemical warfare and weapons development. It takes the reader on a rollercoaster journey from historical times to the present.The Invisible Enemy opens our eyes to how multinational companies and developed nations are working to create some of the most dangerous viruses and biological weapons which can destroy humanity. Chemical and pharma companies have also been the producers of weapons of mass destruction and benefitted from it-be it BASF which produced chemical weapons in World War I, or ICI, the British chemical company which produced a chemical causing blindness. Sandoz, another company, produced LSD, which was part of a chemical warfare project. The British used opium to create drug addicts in the Afghan war.
