Oh, here's a bit of real trivia for you!
Guess what former US president was buried by a foreign government with full presidential honors, and a foreign flag draped over his coffin? Give up? OK
John Tyler! Former President Tyler, a Virginian, was a supporter of that state's secession 1n 1861. He was even elected to the Confederate Congress, but died before he could serve his term.
He was buried with full honors by the government of the Confederate States of America. Now some might argue whether the CSA was a foreign government, but THEY considered themselves as such, and at any rate the US government certainly wasn't going to extend any honors to a secessionist, especially one in enemy territory.
Somethin', huh?
