Coincidence?
Prescott Bush, banker to the Nazis and grandfather of George W. Bush, sponsored the rise of an obscure California right-wing politician who socialized extensively with Nazi sympathizers: Richard M. Nixon.
Richard Nixon hired a "gofer" to assist him with his campaigning and other matters: Mob-connected Jack Ruby who later moved to Dallas.
Just days after the Kennedy assassination, FBI Director J. Edgar Hoover pointedly mentioned "Mr. George Bush of the Central Intelligence Agency" in a memo discussing the reaction of right-wing Cubans to the assassination. Two of the boats used in the infamous Bay of Pigs invasion were coincidentally named "Barbara" (the name of Bush's wife) and "Zapata" the name of his oil company.
Richard Nixon and George Bush are distinguished as being among the only people in America who later claimed they could not remember where they were the day Kennedy was assassinated. (Fast forward to the 45 minute mark.)
And that's just the tip of the iceberg...
