There is an apocryphal story about a nuclear scientist at the Los Alamos proving grounds in the late 1940s. When informed that the Soviet Union had sent spies to infiltrate the complex and steal the secrets of the atomic bomb, he replied that the U.S. should give the Soviet Union all the data on those first atomic bomb tests. His reasoning was, of course, that the Soviets would take years to get through the data regardless what their spies told them and thus not actually build a bomb for many more years.
