Swear a mighty oath

A friend is about to turn in their green card, take the oath and become a citizen. I knew there was an oath involved, but I really had no idea what it entailed. I have provided a link above, but here is the text of the Oath of Allegiance for Naturalized Citizens:

"I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by the law; that I will perform noncombatant service in the Armed Forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely without any mental reservation or purpose of evasion; so help me God."

Wow. Maybe this whole illegal immigration phenomenon is grounded in this oath. You have got to have some stones to stand up and take this one (assuming you are honorable enough to mean what you say). The pledge of allegiance is down right wimpy and sad compared to the oath above. Just for comparison, this is an oath I am more familiar with, the Armed Forces Oath of Enlistment:

"I, __________, 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.''

Still pretty scary stuff (it doesn't seem all that bad when you read it, but when you are repeating after the officer giving you the oath, with your right hand in the air, the whole weight of it just comes crashing down on your shoulders).

But going back to that oath of allegiance, a question for my fellow native born citizens: Would you be willing to take that oath of allegiance if you had to? If the answer is no, do you sleep easy at night?
