Effect and influence of the Iranian revolution on global geopolitics
Iran's Islamic revolution came about mostly in response to US influence in the country. That is not to say that America was the greater evil in the league of successive modern super powers.
But this was the power running the show in this country according to comments by an embittered US diplomat.
The comments were made days after Ayatollah Ruhollah Khomeini returned to Iran in February 1979 when demonstrators briefly attacked the US Embassy in Tehran.
As he prepared to leave Iran the US diplomat said: "We used to run this country. Now we do not even run our own embassy".
The trends continued to a point where the Iranian revolution could be called a movement against the American world order.
This is evident in the regional and global geopolitical change that has come about since the revolution, which was conceived as a dialogue determined to change Iranian society, politics and economy.
With the British withdrawal from the Persian Gulf in 1971 Iran had become the cornerstone of America's security architecture for protecting Western interests in the region.
As both the pivot in the price hike and the sole regional leader willing to break the Arab oil embargo, the Shah had made himself equally consequential for energy markets and the global economy, according to the Brookings Institute.
To both the British and Americans Persia, or Iran, was literally a geopolitical gold mine; rich in oil, it lay between Russia (the USSR) and the warm waters of the South leading to India.
And from an East West perspective, Iran still remains the nexus between Asia and Europe.
