Both all of your statements and those of James_Miller can be true without contradicting each other. Regardless of how modern Iran came to be or who is to blame, you seem to agree that the Iranian public is quite hostile to the U.S. I don't worry about this too much, because I assume that the CIA/DOD/whoever have determined that we can live with a nuke powered Iran, even if they hate us.

This is a bit of a suspicious summary to me, because it sounds exactly like the summary from the angle of a highly educated, perhaps pol sci grad left-leaning highly critical American. Is it really likely that average guy in Iran really has the same perspective? Or their leaders? You simply don't seem to be making any effort to simulate their minds. To give you one example of the lack of simulation here: too long memory. Mossadegh, really? 1953? That is what some guy born in 1970 or 80 will riot about? You have to be half a historian and full of a high-brown person to care what happened in 1953. For comparison, for most people who shot Kennedy and why is ancient history and that was 10 years later, in a country with far better collective memory than Iran (more books published, more media made etc.) If it turns out today the Russkies did it somehow, how many Americans will get angry? My prediction: not many.
