NATO ensures US military protection for the Europeans in case of aggression, but above all it gives the USA supremacy over the Western Bloc. Western European countries agreed to place their armed forces within a defence system under US command, and thus recognize the preponderance of the USA. NATO was founded in 1949 in Washington, but became less prominent after the end of the Cold War. In 2002, it had 19 members : Belgium, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, the UK, the USA, to which were added Greece and Turkey in 1952, the Federal Republic of Germany in 1955 (replaced by Unified Germany in 1990), Spain in 1982, Hungary, Poland and the Czech Republic in 1999.
