I am going to add one more thing:
No one alive today is to credit for the great form of government we were lucky enough to inherit any more than Russians are to blame for the oppressive government history they inherited. But I do think ours is better than theirs.
"I (many millions of names go here) do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God."
