Many people that protested against the government in January are now marching in support of the Islamic Republic and demand that the imperialists are punished. Most of them have protested for economic reasons, they don't want to see their country destroyed and their children murdered by bombs.
Iran is more united than ever because of the imperialist war. That is what you get when you turn state leaders into martyrs.
That sounds made up. Marches largely stopped after bombings, no one marches for IRGC - not even supporters.
And there is no way for anyone to know what Iranians actually think now. No one does the polls there now.
