Was NATO formed to stop fascist aggression?

NATO was formed in 1949 primarily to counter the threat posed by the Soviet Union and its communist expansion during the Cold War, rather than specifically to stop fascist aggression. The alliance aimed to provide collective defense for its member states, ensuring that an attack on one would be considered an attack on all. While the context of its formation was influenced by the aftermath of World War II and the defeat of fascist regimes, NATO's focus shifted to addressing broader security challenges in Europe and North America.
