When I was a cub scout in England we made the Scout promise:
"I promise that I will do my best, to do my duty to God and to the Queen, to help other people
and to keep the Cub Scout Law."
When I joined the Royal Air Force in 1990 I swore another oath:
"I, [name], Swear by Almighty God that I will be Faithful and bear True Allegiance to Her Majesty Queen Elizabeth II, her Heirs and Successors, and that I will, as in Duty bound, Honestly and Faithfully Defend Her Majesty, her Heirs and Successors, in Person, Crown and Dignity against all Enemies and will Observe and Obey all Orders of Her Majesty, her Heirs and Successors, and of the Air Officers and other Officers set over me."
When I became a US citizen in 2006 I swore a final oath...this one is different from the other two because it does not involve allegiance to a person or government, but a promise to defend the Constitution; essentially the written condensation of the ideals on which this nation was founded:
"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."
As with the first two, when I made that last oath, I made it in good faith. Consequently, I have read and understood the Declaration of Independence, the Constitution, the Bill of Rights and I have explored American History in as much detail as I can. I consider myself essentially American and I will defend the Constitution of these United States.......as I trust will all those who have made the same commitment.
