Persians were a much more natural ally, did not the Ayatollah fix that for us back when?
Iran / Persia was either a direct ally or at least supportive of the west for the longest time. The original mid-east oil boom went through Iran. By the 1950's the Iranians waned more sovereign control and economic benefit over the various US & UK oil businesses there. The democratically elected government of Prime Minister Mohammad Mosaddegh was doing just that.
So in 1953 the USA went and engineered a coup and put into power the Shah (Mohammad Reza Pahlavi ). https://en.wikipedia.org/...n_coup_d%27%C3%A9tat
As you can imagine, having a foreign power install a puppet dictator over you wasn't very popular with the Persians. Over the next 20 years the Shah lived a flamboyantly excessive lifestyle while his people grew poorer. He felt safe doing this because he was protected by the US. His secret police killed / tortured dissenters, but overlooked the religious school. That was his mistake. So the people turned to the last organized group that they thought could free them from the Shah's tyranny - the Islamist. In retrospect they traded one tyranny for another. But the moral of this story is that the US got too greedy and created the Ayatollah monster. Now the power of the ayatollahs is waning. The youth is quietly pushing for more liberal, secular freedom. Its a question of time until the theocracy crumbles from within. Starting a war with Iran will strengthen the theocracy. That will be bad for the Iranian people. It will also be bad for the USA, and the rest of the world. The only one's that will benefit from this are: Trump (he will get to be a "war president" just in time for the next election), the House of Saud (by harming the one nation that can challenge their leadership role throughout the Islamic world) and Bibi Netanyahu - who needs a good bogeyman to rally the ultra-nationalists around.
