I'm talking about this letter that was supposedly sent by a freemason called Albert Pike in 1871 accurately describing three world wars. I'm not doubting he wasn't a freemason, that is pretty much certain. If the letter is valid it would be extremely interesting and would probably change how I view the world as a whole. I just heard this theory from my grandpa, but then again he believes pretty much every conspiracy out there. I'm looking for proof that the letter actually exists, because this theory says it's a hoax. I realize there's probably no definitive proof to the existence and validity of the letter but if you're familiar with this theory I would accept some form of proof.
