In what year was the National Security Council established?

The National Security Council was established in 1947 as part of the National Security Act, which was a significant piece of legislation aimed at reorganizing the United States' military and intelligence agencies after World War II. This act created the Council to advise the President on domestic, foreign, and military policy and to coordinate efforts among various agencies. The formation of the National Security Council underscored the importance of a centralized body for dealing with national security matters, reflecting the geopolitical realities of the post-war era, including the onset of the Cold War.

Other years listed correspond to various significant events or legislation, but they do not relate to the establishment of the National Security Council. For example, 1950 is notable for the onset of the Korean War, while 1965 marks the beginning of significant U.S. military involvement in Vietnam. The year 1972 is often associated with the strategic arms limitation talks (SALT) between the U.S. and the Soviet Union. However, none of these years signify the foundational establishment of the National Security Council like 1947 does.
