The Nuclear Arms Race: From First Lightning to Limited Test Ban Treaty

Post-WWII, the US and USSR emerged as superpowers, initiating a nuclear arms race. The Soviet Union's first atomic bomb test in 1949, aided by espionage, shocked the world and led to increased US military spending and the development of the hydrogen bomb.
