The Iranians you met in college, like the ones I had to train with at that time (75-78), are either in charge now in Iran as religious despots and extremists.
Or long imprisoned and dead as enemies of the the religious despots and extremists now ruling Iran.
Yes pretty sure you are right about what happened to them. Several years ago I saw on the news some conference with Iranian officials, I am pretty sure I recognized one.
I was shocked at the level of their hatred for us, I had no idea until I experienced it. They made no secret how they felt about women either. Told me right to my face women should not be in college, and not working. I worked in the security office so at times they had to deal with me.
