National Security Act of 1947

The National Security Act of 1947 is a U.S. law that reorganized the country's military and intelligence agencies after World War II. It established the National Security Council (NSC) to advise the President on security issues, created the Central Intelligence Agency (CIA) to gather and analyze information on foreign threats, and reorganized the Department of Defense to unify the Army, Navy, and Air Force. This act aimed to enhance national security by improving coordination and response to potential threats during the Cold War era. It significantly shaped U.S. foreign policy and defense strategies in subsequent decades.
