Yes; a big question: How will the non-zealot Iranians react to a war their own government started against a fellow moslem country? Those people are already restless when it comes to their government.
After a generation of the ayatollas, I suspect that most of the young Iranians are not all that concerned with the Muslim issues between the Muslim countries. They seem interested in getting back into this century. Unfortunately the Saudis have done their best to promote 17th century Islam in a number of Muslim countries. The war between Sunni and Shia being fought these days is rather like the wars between Catholics and Protestants 4 or 5 centuries ago—the Hundred Years War, the Thirty Years War, the Spanish Inquisition, etc. The latest news on the Iran/Pakistan dust up is they have kissed and made up, which from what I know of the situation of the trans border Baluchi people does not surprise me.
I had been keeping track of the unrest following the clerical murder of the woman with the wrong scarf habits, but that seems to have subsided. Neverthless I think it is quite clear that some day the old guard is going to die and Iran could become quite different, and hopefully better from our perspective, if these religious wars don’t get the rational people killed in the meantime. I think I will pull up the Iran Search pages and look at some of the back articles.
