Changes

The success of Sputnik had a major impact on the Cold War and the United States. Fear that they had fallen behind led U.S. policymakers to accelerate space and weapons programs. In the late 1950s, Soviet Premier Nikita Khrushchev boasted about Soviet technological superiority and growing stockpiles of ICBMs, so the United States worked simultaneously to develop its own ICBMs to counter what it assumed was a growing stockpile of Soviet missiles directed against the United States. With both countries researching new technology, talk of creating a treaty banning nuclear testing faded away for several years. In this way, the launch of Sputnik fueled both the space race and the arms race, in addition to increasing Cold War tensions, as each country worked to prepare new methods of attacking the other.

Eventually, lawmakers and political campaigners in the United States successfully exploited the fear of a “missile gap” developing between U.S. and Soviet nuclear arsenals in the 1960 presidential election, which brought John F. Kennedy to power over Eisenhower’s vice president, Richard Nixon. The Cuban Missile Crisis of 1962 served to remind both sides of the dangers of the weapons they were developing.
