Interestingly enough.. it was mostly Cherokee who were "forcibly" removed. After violating the Treaty of Atocha. Likely most who died on that "Tail of Tears"... were the black slaves who carried the Cherokee baggage.
Slaves who just a few years ago the "Cherokee" Nation..lol, kicked out the decedents of from the tribe. In violation of the Treaty of 1866 entered into after the civil war in which the majority of the Cherokee nation violated all previous treaties by fighting with the Confederacy.
Anywho.... I figure the portrait of one of Americas Great leaders, was a direct shot at Liawatha(warren) as she claims Cherokee blood. Nice dig...brilliant actually.
I doubt the Navajo Codetalkers were bothered by it. Had nothing to do with them.
