NATO and the Warsaw Pact

NATO, otherwise known as the North Atlantic Treaty Organization, is an alliance organization that was created on April 4, 1949 by the United States, Canada, and Western Europe (a total of 12 nations). According to the North Atlantic Treaty, they will protect each other from the spread of Communism as long as the countries cooperate each other. After the fall of Communism, NATO turned from a military organization to a political organization.

The Warsaw Pact is a Soviet version of NATO. Like NATO, it promised the Communist countries from Western attacks if they cooperated each other. The Soviets saw NATO as a threat, so 6 years later (on May 14, 1955), they created the Warsaw pact. However, it wasn't as powerful as NATO. After democratic revolutions erupted within the Warsaw Pact, it was labeled as "nonexistent" in 1991.
