Fallout proves that the atomic bomb was not needed, and was made as a result of a series of flawed decisions. The Americans did not tell the UK that the atomic research was compromised by Soviet spies; the British did not tell the Americans that in 1943 they knew for sure that Germany did not have a nuclear bomb program. Neither country admitted to the scientists developing the bomb that it would never be used to counter the (non-existent) German nuclear threat. Had the scientists known, many of them would have refused to complete work on the bomb.

 

This story shows how politicians fatally failed to understand the nature of atomic science and, in so doing, exposed the world needlessly to great danger, a danger that is still very much with us.
