The problem is that there are radically different interpretations in the words of the Constitution and reputable historians today recognize that this was true at the time of the Founding Father's ratification of the document.

Most of these readings are politically agenda-driven. (Very much like interpretations of the bible or the koran).

Torture was eschewed by George Washington who wouldn't have approved of waterboarding. Jefferson and Madison would not have liked the "new" reading of the Separation of Church and State by the Christian Wrong. David Barton has a very narrow view of the Constitutional constraints as was illustrated well by Beeman on Jon Stewart's program.

The "War Powers Act" was inherent in the Constitution and has been violated by Obama. Bush did seek and receive Congressional authority to invade Iraq.

Congress has done many egregious things in recent times such as the fraudulent censuring of ACORN and Move On. But these didn't violate the Constitution.
Obama did.

And now Libya. Congress was bypassed again.

The Separation of Church and State has been reinterpreted by Wrong-wing scholars who claim authority driven by their politics and religious prejudices.
They deny that it was part of the First Amendment which is a narrow and incoherent reading of that. Congress, in fact, has been pushing religion through prayer breakfasts and litmus tests for office. How many non-religious people are in government today?

"The second is freedom of every person to worship God in his own way--everywhere in the world."

Or not worship any god at all. That is also implied in the First Amendment, along with not using belief as a litmus test for office.

Kendall, Howard Zinn, at one time a bombardier in WWII, would have agreed with you. I'm with Zinn.

The problem with the UN today is that it is strong-armed by the US but not as badly as NATO.

The Constitution has been and remains a living breathing document that is interpreted by so many differently. The Founding Fathers couldn't agree on it so how can anyone today do so aside from their political bias?
