President Harry S. Truman signs the National Security Bill, which establishes the Department of Defense. As the Cold War heated up, the Department of Defense became the cornerstone of America’s military effort to add the expansion of communism.
In 1947, the National Security Act established the Cabinet-level position of secretary of defense, which oversaw a fairly unwieldy umbrella military-defense agency referred to as the National Military Establishment. The secretary of defense, however, was an individual of a level of military-related cabinet positions just, like the pre-current secretaries for the Army, Navy, and Air Force. The growing complexity of the Cold War, a war where the mishandled application of military force may lead to a globe war of cataclysmic proportions, convinced U.S. officials that the 1947 act essential to be revised.
In 1949, the National Security Bill streamlined the defense agencies of the U.S. government. The 1949 bill replaced the National Military Establishment with the Department of Defense. The bill also removed the cabinet-level status of the secretaries of the Army, Navy, and Air Force, who henceforth be subordinate to the Secretary of Defense. The 1st person to carry this position was Louis Johnson. Finally, the bill supplied for the workplace of chairman of the Joint Chiefs of Staff in order to bring to complete to the inter-service bickering that had characterized the Joint Chiefs recently. World War II hero General Omar Bradley was appointed the 1st Chairman of the Joint Chiefs of Staff.
The National Security Bill of 1949 was the consequence of the realization that a lot more coordination and efficiency have been necessary for America’s military-defense bureaucracy, which had skilled tremendous development throughout and immediately after World War II. The Cold War was a fresh and unsafe sort of war for America, and the 1949 reorganization was recognition of the necessity for a various technique to U.S. defense.
