NATO and the Warsaw Pact

NATO is an organization that includes some countries in Europe and North America.
The Warsaw Pact was formed as communist military alliance to maintain power over Eastern Europe. The major reason for the formation of NATO was that the countries involved wanted a defense alliance so that if one of the countries were to be attacked all of the other countries in NATO would come and help. The Warsaw Pact was made by Russia and many other republics in Europe. The countries within the Warsaw Pact promised to defend each other if any other country within the alliance was attacked.
