I think people are reading too far into this. They are protests. Protests happen all the time everywhere. The Iranian government is probably safe for now. This is something I would keep an eye on though because it could escalate. Hopefully not, because anyone who thinks the Iranian government will fall and then there will be a modern, democratic, peaceful Iran is mistaken. The Iranian government remains with a lot of public support. Rouhani was just re-elected by a very strong landslide. There is also Syria, Hezbollah, the Iraqi PMU who have benefited from years of Iranian support and may want to return the favour.
Rouhani is a moderate reformist. His opponents he beat in a landslide were the hardliners.
I think thumb's point is that the election had a decent turnout giving the regime a bit of 'legitimacy'.
