What we have now is the exact opposite of what the founders had in mind. From Jacob G. Hornberger at fff.org:
The worst mistake that the American people have made in the entire history of the United States was to permit the conversion of the federal government to a national-security state. That conversion has played a major role in the destruction of our liberty, privacy, and economic well-being.
What is a national-security state? It is a totalitarian-like governmental structure that consists of an enormous military-intelligence establishment with extraordinary powers, such as indefinite detention, torture, secret surveillance, and even assassination of both citizens and foreigners.
To put the matter into a larger context, North Korea is a national-security state. So are Egypt, China, Cuba, and Russia. And the United States. All of the regimes in those countries wield totalitarian-like powers.
It wasn’t always that way in the United States. Our nation was founded as a limited-government republic and remained that way for nearly 150 years. No Pentagon, no CIA, and no NSA. There was an army but it was relatively small — big enough to win battles against Indian tribes or a neighboring weak and impoverished country such as Mexico, but nowhere big enough to engage in wars around the world.
