Iran - how vulnerable is the regime?

The issues that drove Iranians to the streets, a great personal cost, remain intact. They are structural. They're very difficult for the regime to do away with. These are economic grievances that have been made worse by the US administration's maximum pressure campaign, and by that I mean US-led international sanctions against Iran, which has made it very difficult to address the core day-to-day requirements of average Iranians, and that's not going away anytime soon."
