Descriptions are for the weak.
The real reason for the official secrecy, in most instances, is not to keep the opposition (the CIA’s euphemistic term for the enemy) from knowing what is going on; the enemy usually does know. The basic reason for governmental secrecy is to keep you, the American public, from knowing - for you, too, are considered the opposition, or enemy – so that you cannot interfere. When the public does not know what the government or the CIA is doing, it cannot voice its approval or disapproval of their actions. In fact, they can even lie to your about what they are doing or have done, and you will not know it. As for the second advantage, despite frequent suggestion that the CIA is a rogue elephant, the truth is that the agency functions at the direction of and in response to the office of the president. All of its major clandestine operations are carried out with the direct approval of or on direct orders from the White House. The CIA is a secret tool of the president – every president. And every president since Truman has lied to the American people in order to protect the agency. When lies have failed, it has been the duty of the CIA to take the blame for the president, thus protecting him. This is known in the business as “plausible denial.” The CIA, functioning as a secret instrument of the U.S. government and the presidency, has long misused and abused history and continues to do so.
