This is the oath that George took:
"I do solemnly swear (or affirm) that I will faithfully execute the office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States."
It's not a difficult oath to remember. New members of our armed forces take one very similar every day.
The core of the oath every person wearing a Marine Corps, Air Force, Army or Naval uniform, on Iraqi soil and off, right this second, swore when they enlisted, is to "support and defend the Constitution of the United States against all enemies foreign and domestic;" and to "bear true faith and allegiance to the same. "
There's not much more than that -- obedience to the lawful orders of superiors (including the Commander-in-Chief) in adherence to the Uniform Code of Military Justice. The usual.
But the Constitution.
The Constitution is the core of this oath, the basis for our system of government, and without it we cease to be Americans. It's not even the basis, it is our system of government. It is the definition of the United States of America. It is the compact the Founding Fathers made with one another and with posterity. We make that compact anew every time someone takes that oath. That is why we must preserve the Constitution, must protect it, must defend it if we want to continue to call ourselves Americans.
Well and so. Points for effort, Mr. President, but with regards to the preservation, protection and defense of the Constitution, I'm afraid I have to give you an 'F'. You can't protect a thing by destroying it. You owe us, all of us, in service and civilian, much more than that.
The Constitution of the United States of America
