When foreigners apply to become naturalized as American citizens, they are required to take the following oath:

"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."

We have a domestic enemy from whom to defend the constitution. Anyone who refuses that fight, instead renouncing their citizenship and fleeing, proves for all time they are unworthy to take this oath, and thus unworthy of citizenship.

Those who leave shall not be permitted to return.
