1963: On June 4th President John F. Kennedy (the 35th President of the United States 1961 – 1963) signs Executive Order 11110 which returned to the U.S. government the power to issue currency, without going through the Rosthchilds owned Federal Reserve.
Less than 6 months later on November 22nd , president Kennedy is assassinated by the Rothschilds for the same reason as they assassinated President Abraham Lincoln in 1865, he wanted to print American money for the American people, as oppose to for the benefit of a money grabbing war mongering foreign elite.
This Executive Order 11110, is rescinded by President Lyndon Baines Johnson (the 36th President of the United States 1963 to 1969) on Air Force One from Dallas to Washington, the same day as President Kennedy was assassinated.
Another, and probably the primary, reason for Kennedy's assassination is however, the fact that he made it quite clear to Israeli Prime Minister, David Ben-Gurion, that under no circumstances would he agree to Israel becoming a nuclear state. The Israeli newspaper Ha'aretz on February 5, 1999, in a review of, Avner Cohen's book, "Israel and the Bomb," states the following,
"The murder of American President John F. Kennedy brought to an abrupt end the massive pressure being applied by the U.S. administration on the government of Israel to discontinue the nuclear program...The book implied that, had Kennedy remained alive, it is doubtful whether Israel would today have a nuclear option."
