NATO and The Warsaw Pact

NATO is an organization that the countries in Europe and North America formed to try to stop communist nations. One major reason that NATO was formed because  countries involved wanted a mutual defense alliance so that if one of them were attacked all of the other countries in NATO would come to their aide, just like as if World War I.

 The Warsaw Pact consisted mostly of the Soviet Union and other Communist countries.  It was supposed to be another mutual defense alliance like the one that NATO had, and was created in response to it.  The Soviet Union was the biggest and most powerful country in the alliance.  The Soviet Union kept part of their military in the other countries in the alliance to make them socialist nations.  

The countries involved in NATO were Belgium, the Netherlands, Luxembourg, France and the United Kingdom, later followed by the United States, Canada, Portugal, Italy, Norway, Denmark and Iceland.

The Warsaw Pact included Albania, Bulgaria, Czechoslovak, Hungary, Poland, Romania, West Germany, and the USSR.
