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 law; that I will perform noncombatant service in the Armed Forces of the United States when required by law; that I will perform work of national importance under civilian direction when required by law; and that I take this obligation freely without any mental reservation or purpose of evasion; so help me God.

There's the oath and there's actual policy. Though, I guess a fully honorable person would keep the oath and renounce:

There are always varying levels.

Ideally they'll resonate.

Why would one choose dishonor?

Easier than being honorable.

Not always a choice -- some countries make it basically impossible to renounce citizenship.

Care to elaborate?

Now you know the price of your honor. This is an opportunity few men survive. Who are men.
