In addition to pass secrets to the communist Soviet Union about the design of the [[atomic bomb]] and, after the war, initial attempts to design a [[hydrogen bomb]], Fuchs also gave production information that allowed the Soviet Union to estimate how many atomic bombs the United States had. As a result the Soviet Union realized that the United States was not as formidable as one might expect, because it did not hold enough atomic bombs to thwart massive communist aggression in the late 1940s and early 1950s. | In addition to pass secrets to the communist Soviet Union about the design of the [[atomic bomb]] and, after the war, initial attempts to design a [[hydrogen bomb]], Fuchs also gave production information that allowed the Soviet Union to estimate how many atomic bombs the United States had.
