Late Shah’s speech on OPEC in 1973 that led to his downfall.

It was not a revolution in 1979. It was a hostile take over by the british and Islamic arab terrorists bent on destroying Iran and taking control of the oil fields. In 1973 the Shah intended to free Iran from unfair oil contracts that was supposed to end in 1979. That did not happen. Except, the brits and Jimmy Carter gave Iran a terrorist mullah called Khomeini & his ideology who not only killed Iranians but indirectly was responsible in murdering many Westerners.
The Islamofascist snakes they have supported since 1979 will eventually bite them real good.
