Michael Glennon points that there are many agencies and departments - military, intelligence, law enforcement, diplomats and others - that constitute the national security. This means that the U.S government that is elected - president and congressman - are not the ones that take care of national security directly: “America’s efficient institution makes most of the key decisions concerning national security, removed from public view and from the constitutional restrictions that check America’s dignified institutions”
Glennon bases this argument by the National Security Act of 1947 that created the foundation of the modern system. This act also gave agencies and departments self-regulating and self-reinforcing policies and gave more autonomy to them.
