A destabilized Iran, no. But the Iranian personality is more balanced than the Arab. They’ve been civilized for millenia before the coming of Islam and then the Mongols, and they don’t stay destabilized for long. Somewhat like the Chinese. As such, they might just turn out alright when the dust settles.
This is seeming way too much like manipulated regime change which benefits Saudi Arabia and Israel, because they do control their internal environment and increase power if countries surrounding them fail. I do hope this President isn't buying into regime change. One issue that got him elected was that he was opposed to meddling in foreign governments.
