A recent tv show highlighted the nuclear race between the US and Russia. The USA tested a bomb xxxx times stronger than the one used on Japan; because the scientists were ignorant that the material used to make the bomb would lead to an even greater explosion than known, much radioactivity destroyed the beautiful Bikini Islands and spread further than expected. To outdo them, Sakharov helped Russia build the Tsar bomb, even bigger (100x bigger than one used in WWII); and of course, this caused so much damage, Sakharov went on to become a peace activist. If you remember, Russia threatened the USA it would use the bomb everyday. Finally a test ban treaty was signed. However, using the bomb as a threat, using the bomb??? and ignorance of the nature of nuclear material still exist.
