== Leading to the RDS-37 == left|thumb|Sketch by Sakharov in 1954 of the Soviet hydrogen bomb concept: The RDS-37 was a reaction to the efforts of the United States. Previously, the Soviet Union allegedly used many of their spies in the U.S. to help them generate methods and ideas for the nuclear bomb. The creation of the hydrogen bomb required less usage of this method, although they still received help from some spies, most importantly, Klaus Fuchs.
