By 1963, roughly 20 years after the Brenton Woods Agreement, the US was almost (not until 1971) under full fiat monetary credit expansion. During Kennedy's presidency, he created executive order 11110, which was a continuation of silver money created by the United States Treasury. Can anyone today imagine what that means? In other words, the US Treasury, originally and still does to this day, had/has the power to coin and mint money interest FREE, the public had NO obligation to pay interest on money like we do today from the Federal Reserve, which is a private company owned by stockholders.
Anyway, Kennedy was killed because he didn't act fast enough to eliminate real money, we was supposed to get rid of ALL gold/silver money and strictly use fiat currency created by the Federal Reserve. Quickly after he was killed, all silver was gon by 1964 and later other executive orders were used to remove all the wording Kennedy used in his executive order.
Who knows who killed him, doesn't matter, fact is, when you screw with bankers, you die financially or for real, just ask President Lincoln.
