alt Hacker News> look like what happened in Libya: A failed state that falls in anarchy.
This comment just shows that you have no idea what Iran is, and how it differs from Libya.
Libya is a loose conglomerate of tribes. Iran majorly Persian that see themselves as one nation. Completely different dynamics.
It doesn't matter - when a strong and stable political structures suddenly collapse, the state fails and disintegrates due to the political infighting. While I agree with you that the chances of Iran becoming a completely failed state is unlikely, I do see an imminent civil war in Iran's future if a regime collapse happens, and the Americans and Israelis install their Shahi (royal) puppet there. A regime collapse will of course mean Iran will lose its sovereignty (probably for a decade or more), till a truly independent stable polity emerges form the ashes.
