North Atlantic Treaty Organization, an intergovernmental military alliance between 29 countries. NATO. NATO is a military alliance formed in 1949 to provide collective security against the Soviet Union and its allies during the Cold War.
During the Cold War, from 1945 to 1960, NATO was formed to unite Western countries against the spread of communism led by the Soviet Union. It was important because it provided a collective defense system, meaning if one member was attacked, others would come to its aid, strengthening security and deterring potential attacks. This responded to the fear of Soviet expansion and aggression after World War II. Today, NATO still matters because it protects member countries and maintains global peace and security, as seen in its support for Ukraine in response to Russian aggression. This affects people today by providing stability, ensuring safer international travel, and allowing countries to focus resources on other important issues, such as education and health care, instead of solely on military defense.
