 * Expanding Power**

**Military Competition** North Korea and South Korea were enemies. North Korea was communist along with the Soviet Union and South Korea was democratic along with the United States. The United States tried to keep communist low through out the world and the Soviet Union wanted it to spread. Becoming communist, North Korea's economy fell, but with the help of the United States the economy of South Korea became better.

**Arms and Space Race** The nuclear arms race was a competition in nuclear warfare between the United States, and the Soviet Union, and their respective allies during the Cold War. During the Cold War, in addition to the American and Soviet nuclear stockpiles, other countries also developed nuclear weapons, though none engaged in warhead production on nearly the same scale as the two superpowers.

The Space Race was an informal competition between the Unites States and the Soviet Union, as they tried to match or beat the others accomplishments in exploring outer space. It involved the efforts to explore outer space with satellites to send man into space, and to land him on the Moon.

The Space Race effectively began after the Soviet launch of Sputnik 1 on October 4, 1957. The Space Race became an important part of the cultural, technological, and ideological rivalry between the United States and the Soviet Union during the Cold War. Space Technology became a particularly important arena in this conflict, because of both its potential military applications and the morale-boosting social benefits.
