Here's this anon's view of Iran.
There is a large segment of the Iranian population who are good people and not involved with Islamic Jihad, such as the original Persians, many of whom are Zoroastrian or not religiously affiliated. Unfortunately, Iran is ruled by Jihadist leaders, who also control the IRGC (Islamic Revolutionary Guard Corps).
It would seem that pushing out the leaders would solve the problem, but here's the issue:
The IRGC is populated by those involved in Islamic Jihad (i.e. militant Jihadists). So, to overthrow Iran's leaders would also require overthrowing a large portion of their military.
When Iran is finally backed into a corner, they will most likely take the kamikaze/martyr route, but on a national military scale. Their "Islamic messiah" cannot come until Israel is destroyed, so guess where they're headed.
I also envision that at that time, they will be joined by other Islamic nations, and maybe also even non-Islamic nations (China?).
It will be Armageddon, but the good news is that God will save Israel (the holy remnant), and all of these evil forces will be destroyed by God in such as way as to definitively reveal God's presence in the world to all, as it was in the exodus from Egypt.
For God's sake.
