What Is the National Security Act of 1947?

The National Security Act was an influential reformation made to the United States' foreign and military groups that served as major basis for military and foreign policies. It was also responsible for the formation of the Central Intelligence Agency, commonly known as the CIA.

The National Security Act was enacted as a defensive strategy due to threats the United States faced during the Cold War. President Harry Truman was responsible for signing it into action. The act led to the creation of several groups that served to organize and more efficiently manage foreign and military issues.

The National Security Council was created to manage security issues the nation was facing, and included important officials such as the President, Secretary of Defense, and the Secretary of State. The National Security Act resulted in the merging of the military's Naval Department and War Department into the Department of Defense, which was responsible for the management of the expanding military. The Secretary of Defense then created the Air Force. The Central Intelligence Agency was formed from the Office of Strategic Services, and its functions include covert operations and the gathering of information on foreign countries. Under these new agencies, military, foreign and intelligence affairs were more easily managed and could operate with much more efficiency.
