Small sample, but talking about this with my Iranian friends, the sentiment among them and their wider network is that they do acknowledge that Iran has problems, that they need a change in leadership, but that they do NOT want a regime change at the hands of the US/Israel. For them that is a recipe for disaster and more carnage.

In their view, the topology of Iranians and their political views would be: 10% - pro-US regime change intervention; 20% - ardent regime supporters; 70% - pro-regime change but without US involvement.
