An apologist historic misrepresentation.  The Shah was in firm control of Iranian politics when Carter intervened, convincing the Shah to abdicate to avoid a violent revolution.  There was a political movement underway in Iran to confront the Shah control, but it was more like two opposing political parties in rhetoric.  The political differences could have been non-violently resolved.  The political vacuum created by the Shah's abdication created the violent take over that followed.  Carter's intervention resulted in a violent usurpation of authority that, together with the Carter support of the Iraqi administration, led to the eight year war between Iraq and Iran.  What has followed has been a violence-oriented adjustment of authority throughout the Middle East that is still underway with America still in the middle.  Thank you Jimmy Carter.
