NATO and the Warsaw Pact

The North Atlantic Treaty Organization (NATO) includes countries in Europe and North America. It was created to help defend each other. In case one of the countries gets into a war, all of the other countries that are in NATO will join the fight too. The agreement also helps European nations with economic aide. The Warsaw pact was created in response to NATO. It consisted mostly of the Soviet Union and its satellite countries.
The Soviet Union had control over the alliance. At the end of the 1980s the political scene damaged the organization badly. The USSR started to remove the troops that they had stationed in the other countries that were in the Warsaw Pact.
