What did the military alliance Nato want to keep Soviets from doing?

NATO was established in 1949 primarily to deter Soviet expansion and influence in Europe during the Cold War. The alliance aimed to provide collective security for its member states, ensuring that an attack on one would be considered an attack on all. By presenting a unified front, NATO sought to prevent the Soviets from spreading communism and undermining democratic governments in Western Europe. Ultimately, NATO's goal was to maintain stability and balance of power in the region.
