Atomic physicist Lawrence H. Johnston, one of the last survivors of the Manhattan Project that created the atomic bomb, died Sunday at his Moscow home of lung cancer. Johnston, 93, designed the detonator for the bombs that were detonated at White Sands, N.M., and Nagasaki, Japan, and is believed to be the only eyewitness to all three of the 1945 atomic explosions that also included Hiroshima, Japan. His later assignment was to measure the impacts of the bombs. He was a professor of physics at the University of Idaho from 1967 to 1988/Lewiston Tribune. More here.

Question: Was the Manhattan Project a good thing/bad thing for this country?
