Che Guevara and Lyndon Johnson ( DALLAS, DUH!) got together. LBJ hated JFK. He had all the backroom politics down pat, connections etc. so he was very jealous and angry taking a back seat to the young Kennedys.
He calls Che, who hates LBJ a bit less than he hates the Kennedys.
Che calls longtime friend Fats Domino who played in Jack Ruby's club often. Ruby had a friend named Oswald who married his own sister and was molested as a child by a heroin addicted Methodist . Ruby sent Oswald, the rest is history.
Oh. Fats blackmails Ruby about Oswald, so he shoots Oswald in exchange for his family being "taken care of" like the old Jewish Empire.
His family now resides in Cienfuegos Cuba.

NOOOOOO? Prove it!
