Fifteen years previously it had been the site of the government-owned Bonneville Nucleonic Weapons Research Laboratory. Here, American scientists, working in collaboration with the United States of Europe Federal Research Institute at Geneva, had developed the theory of meson dynamics that led to the nucleonic bomb. The theory predicted a "clean" reaction with a yield an order of magnitude greater than that produced by thermonuclear fusion. The holes they had blown in the Sahara had proved it.
