I kmow there is a wide discontent in Iran. But I am quite sure that had the people known what this would be used as a pretext for, they would use more judgement.
They just forgot for a moment that regardless of what ayatollahs tell about internal affairs, what they tell about the west is quite true.
The bazaars / markets were completely closed in January because Iran’s inflation made importing goods impossibly affordable.
While the riots align with US interests, they also align with the interests of lots of Iranian people.
