Re the king of england(may he forever be damned to hell) this vid claims: "that treaty specifically identifies the king of england as the prince of the united states"
That claim aint there:

In the beginning of the treaty there's some ass-kiss'n where there should a been more ass-whipp'n, and tea-bag'n, but other than that, there's no statement declaring a prince of the united states.
