The National Security Act of 1947 was an essential piece of legislation that significantly impacted how Presidents formulated and implemented foreign policy. This act created many vital institutions for any president looking to use them over time, including the NSC with its 17 member council responsible for coordinating security matters between the military and the State Department officials dealing abroad. It also set up a framework on what information they should have access to when formulating policies towards certain regions within world affairs. The preparation of the meeting process begins at least four weeks before convening so that members can get acquainted through presentations by those who work in the relevant departments.
The National Security Act led to the National Security Council’s creation, a group of top-level advisors to the president who meet at times to discuss long-term problems and more immediate national security issues. The council includes cabinet members and anyone else the president appoints from outside sources. There’s always someone who can speak for the president’s particular point of view on things like foreign policy with other countries.
The National Security Act was one of the most important legislation passed in US history. The act created several organizations, including the Central Intelligence Agency (CIA), which grew out of the Office for Wartime Intelligence Services and small post-war groups. The CIA served as the primary civilian agency responsible for gathering information about defense against the communist threat.
In 1949, President Truman amended the act to give more power over individual services and their secretaries. The War Department and the Navy department were merged into a single Department of Defence that came under the purview of the Secretary of Defense, who also headed the newly created Air Force Department. However, each branch maintained its secretary.
