Let's get something clear from the start. In 1976, in his 20s, John Brennan was a card carrying communist who supported the then Soviet Union, at the height some might say of the Cold War, so much so he voted and assisted Gus Hall, the communist candidate for President against a devout Christian, Jimmy Carter who ultimately won the Presidency.
Yet under four years later, just after the then Soviet Union invaded, just weeks before, Afghanistan and months after the tumultuous Iranian revolution of 1979, which at the time many thought the Soviet Union had a hand in, Brennan was accepted into the CIA as a junior analyst.
At that time, John Brennan should have never got into the CIA, or any Western Intelligence agency given his communist background.
Think on that carefully as you continue to read this.
Also reflect on the fact that Brennan, later in his CIA career, was surprisingly elevated from junior analyst to the prestigious position of Station Chief in Saudi Arabia where he spent a few years.
