What is the history of chemical and nuclear warfare?

The first official chemical warfare started in WWI when the military threw bombs containing ammonia to the other side. The ammonia was mass produced through a new method called the Heiber process. The inventor got a Nobel Prize but his wife killed herself at the thought that his process killed so many people.


The nuclear warfare began with US dropping the atomic bomb on Hiroshima and Nagasaki in 1945. Since then, the nuclear war developed to a horrible extent. The Czar bomb, which is said to be the strongest weapon of mass destruction ever tested, sent shock waves around the globe three times before it died down.
