Just 47 years ago, on November 22, 1963, President John F. Kennedy was assassinated in Dallas, Texas. This marked the turning of the American National Security State apparatus against its own leadership. After having overthrown, assassinated leaders, and orchestrated coups around the world, the moment its growing power was threatened by the civilian leadership in America, the apparatus of empire came home to roost.
The National Security State
The apparatus of the National Security State, largely established in the National Security Act of 1947, laid the foundations for the extension of American hegemony around the globe. In short, the Act laid the foundations for the apparatus of the American Empire. The National Security Act created the National Security Council (NSC) and position of National Security Adviser, as well as the Joint Chiefs of Staff (JSC) as the Pentagon high command of military leaders, and of course, the CIA.
