It occurs to me, the underlined words are what the entire American Revolution was about, full stop ...
CREATING AN ENGLISH KING
Here are the words of the proclamation announcing that Prince Charles had become King Charles the III on September 10, 2022 (quoted from a CBS News report):
The proclamation, as read out to the world by the Garter King of Arms, saw the assembled Privy Counsellors and other members of the Accession Council formally declare that they "do now hereby with one voice and Consent of Tongue and Heart, publish and proclaim that the Prince Charles Philip Arthur George is now, by the death of our late Sovereign of happy memory, become our only lawful and rightful liege lord, Charles the III, by the Grace of God, of the United Kingdom of Great Britain and Northern Ireland and of all His other Realms and Territories, King, Head of the Commonwealth, Defender of the Faith, to whom we do acknowledge all Faith and Obedience with humble Affection, beseeching God by whom Kings and Queens do reign, to bless his majesty with long and happy Years to reign over us."
CREATING A U.S. PRESIDENT
Here is the oath that Joe Biden swore on January 20, 2021:
"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."
246 years later, really nothing has changed.
One becomes "Liege Lord" of a nation (or really nations) upon the death of the prior sovereign and that nation's subjects then pledge "all faith and obedience" to that individual as long as they shall reign.
The other goes before the people, asks for support in an election and upon receiving a sufficient amount of that support, pledges to "preserve, protect and defend" principles and practices regarding the conduct of their government and the rules by which decisions shall be made, subject to review every four years.
