His many worries are detailed in an op-ed he has in the Washington Post today entitled, "What Worries Me Most After Five Years as Leader of the NSA."

Surprisingly, for some unknown reason, Nakasone expressed no worry whatsoever about the "invasion" of illegal immigrants on our southern border. Wouldn't you think that a career military man and the head of the NSA would be worried about an ongoing "invasion" of our nation? Sounds like a grave case of military malpractice to me.

Nakasone's role as a military general helps to remind us of the gigantic military-intelligence establishment that controls our country. It's easy to view the Pentagon, the CIA, and the NSA as three separate and distinct entities. In actuality, they are three parts of an overall entity known as the national-security establishment. It is one gigantic military-intelligence entity that is simply divided into three parts — the Pentagon, the CIA, and the NSA.

Longtime readers of my work know that I have long recommended a book entitled National Security and Double Government by Michael J. Glennon, who is a professor of law at Tufts University and former legal counsel to the Senate Foreign Relations Committee. Glennon's thesis, to which I subscribe, is an ominous one: The national-security establishment — not the president, Congress, or Supreme Court — runs the federal government, especially when it comes to foreign affairs.

The federal government was not always a national-security state. For more than 150 years, Americans lived under a type of governmental structure known as a limited-government republic.

The difference between a limited-government republic and a national-security state is day and night. The powers of a limited-government republic are limited to those enumerated in the Constitution and are also restricted by the Bill of Rights. The powers of a national-security state are omnipotent and unrestricted by anything, including the powers of torture, assassination, and indefinite detention, not to mention coups, invasions, occupations, and wars of aggression.
