Ok, I will tell you my opinion about ongoing process and possible consequences... After dismantled Axis and last events, we can conclude that zionists inflicted major, maybe fatal blow to IR... Islamic Republic can hardly find excuse to rising Iranian nationalism, when in the end Iran was left to clash with Israelis toe-to-toe alone...
I am not fully agree that IR was historical failure for Iranian nation, but it would be wise for Iran to completely get out of those Arabian areas, that are accusing Iran for their own limitations...
Probably some preparation for unavoidable reforms in Iran are going on behind the scenes, but any forcefully changes of Khamenei will be disastrous for Iran...redefining of doctrine should be done naturally, and after closing any possibility of aggression by zionists ..
