Which is NOT one of the roles in which nuclear weapons technology played in the development of the Cold War era?
1.The existence of atom bombs raised the stakes of post-war foreign policy
2.The Soviets after World War II did not develop atomic weapons
3.Between the two superpowers the US and the USSR from the 1940s, there was an active arms race
4.Evidence in the US that the Soviets had stolen the 'secret' of the atomic bomb; this leak in information led the US to consider the Soviets were a competant foe, not to be taken lightly
