Carter & Brzezinski were not the main designers of the So called Iranian Revolution, but it was the British MI6 and Soviet KGB whom were the main Planners since they knew the Iranian Psychology the best. In US Politics you hear the term Good Guys And Bad Guys, since this was a Secretive Intelligence Operation, Americans played the Bad Guys part while the main planners ie British and Russians remained the Good Guys up to now in Iran.
Russians have the head of the Cat and the British have the south of our beloved fatherland as of today.
