What I come back to when I think of Iran is that I knew a lot of young Iranians when I was going to school. Young idealistic people who were at the time very anti-Shah.

At the time I was entirely unaware of the U.S. history of subverting and ending a nascent Democracy in Iran, the Mossadegh regime. I'll bet each of my fellow Iranian students (actually they were mostly grad students while I was undergrad) was well aware of that sordid past and could have given me chapter and verse of their unhappy history. It took a book many years later called "All The Shah's Men" to bring me up to date.

However Ayatollah Khomeini was an ugly evil minded SOB who came back to his country with murder on his mind and in his heart and his truth was a TRUTH that led directly to the deaths of his enemies and additional deaths of people who were too secular or of the wrong religion (sudh as Ba'Hai). The regime that took the Shah's place has been far worse, far more backwards and far more bloody than the Shah.

They are financiers and exporters of terror. They institutionalize hate in their government controlled religious observances.

I think Obama took a measured attitude when he hammered out the nuclear agreement with the Iran regime. It was: "these are bad people, let's at least limit the amount of bad they can do."
I was in favor of the agreement, and I thought Trump's campaign argument that it was a horrible deal was a terrible approach, but that and other things got him elected.

Whether or not that puts nukes back in the mix is not known, but if it's nukes for Iran, why won't the Saudis go there. They can afford the same amount of centrifuges the Iranians can.

It reminds me of a book title: "Only the Paranoid Survive". That is the world Obama was trying to avoid, and that is the world that Trump and his enablers have potentially put us back in. The first is a case of leadership and the second is a case of mental instability feeding on itself.

I apologize for this being off-topic. I think the Yemenis were going to get beat up in any case. They don't have any oil.
