What was the purpose of NATO and seato?

NATO (North Atlantic Treaty Organization) was established in 1949 to provide collective defense against potential aggression from the Soviet Union and to promote stability in the North Atlantic region. SEATO (Southeast Asia Treaty Organization), formed in 1954, aimed to prevent the spread of communism in Southeast Asia by providing a mutual defense framework among member countries. Both organizations sought to enhance security through military alliances and cooperation among member states during the Cold War.
