How did the 1953 coup eventually lead up to the 1979 islamic revolution?

Jimmy Carter wanted the Shah to be a stronger force in the Persian gulf and he refused so the c.i.a. caused a revolution in order to have reason to put a military presence in the gulf .That's where Saddam Hussein came from we made him up .The Shah died like 5 months later just so there was no chance he would be made ruler again .The government won't tell you that .That's what the c.i.a does though.
