The MI6 played a leading role along with the CIA in removing the democratically elected Mossadegh in Iran in 1953 and replacing him with the Shah.
They've also done f***ed up s*** in Kenya and other former colonies. Same goes for France and its intelligence agencies as well.
That + replacing the shah with the ayatollah was their doing too
Intelligence agencies are devils, it's so funny that Democrats now suck their d*** cuz they hate Trump so much.
