The words do not fit any one head of state.
Yes the cover does depict the French Revolution. But, Viva la Vida, Long Live Life, is Spanish. And, Louis xvi never ruled the world. Seas or naval fleets did not rise upon his word.
Louis xvi inherited a France heavily in debt from the Seven Years War, a non existant army, and a decimated Navy. Nearly all French Colonial territories ceded to Great Britain and Spain before Louis xvi was coronated.
Louis xvi had the unenviable task of rebuilding a war battered empire, and although well liked, intellegent, and well educated, he lacked the means and confidence to do so.
He, and the queen became easy targets of rumors and "libelles". "Never an honest word" fit the period of Louis xvi, but the deceit was not from the throne, but against it.
In the context of the French Revolution, the song more closely resembles Maximilien Robespierre, who rose to power from the revolution. In one rear of terror 40, 000 French men and women were executed under Robespierre.
Although he commanded no Navy, seas of spies rose up upon Robespierre's word. But, there were no crowds singing "Long Live the King" under Maximilien Robespierre. That transgression would get them executed.
Maximilien Robespierre and the Revolution paved a road to hell with good intentions. Ultimately Robespierre himself was guillotined.
Louis xvi may have felt "For some reason I cannot explain, I know Saint Peter won't call my name". But, that would more likely be due to his clinical depression than to any mortal sins.
On the other hand, Robespierre did not comprehend his guilt for complicity in the genocide of 40, 000. For him, the end of the monarchy was a rationalization for his brutality and terrorism. He would not have been able to explain why Saint Peter would not call his name.
