On the domestic front, however, this tragic accident could have much deeper repercussions.https://www.bbc.co.uk/news/world-middle-east-51081826
Just days before the flight crashed, Iran displayed an unprecedented level of unity and popular support when millions of people poured on to the streets all over the country to mourn the death of Soleimani.
This seemed to indicate that, when faced with the external threat of military confrontation, Iranians from different political and economic backgrounds could come together and put aside their divisions.
But the shooting down of flight PS752 and the subsequent denials from the authorities could lead these divisions to re-emerge and become even sharper.
While the admission of guilt could assuage some of the popular criticism towards the grave mishandling of the situation, the establishment might still be perceived as having tried to hide evidence and avoid responsibility before international pressure mounted on Iran to come clean.
This is likely to revive the divisions and unrest that erupted in November when the Iranian government approved a sharp spike in fuel prices. This move triggered large demonstrations across the country and resulted in widespread repression and the killing of at least 300 people.
While acknowledging the truth is an important first step, the Iranian people will likely demand accountability and the prosecution of those responsible, as well as the adoption of all the steps needed to ensure this does not happen again.
They will also pay attention to how the victims of the air crash are treated by the Iranian elite. An important test here is whether their funerals will result in national mourning, similar to that of Soleimani, or instead be largely ignored.
All of these demands will be added to previous grievances over the state of the economy and the limitations on some social freedoms.
Parliamentary elections are due to take place in just over a month and internal discord over this crash could lead to further unrest. Plus, tension with the West has abated but is far from over.
The way in which the government and the rest of the establishment handle the broader repercussions of this plane crash could be a watershed moment for Iran. The choices it makes are likely to reverberate throughout Iranian politics and society for months, or even years, to come.
I've heard reports that that show of unity was not necessarily voluntary. Here's an excerpt from the left-wing rag the Washington Post
"Without doubt, Soleimani had support among hard-liners and regime loyalists. The regime is not taking any chances, though. In the city of Ahvaz, where large numbers of people turned out to mourn Soleimani, the government has forced students and officials to attend. It provided free transport and ordered shops to shut down. According to videos sent to me by people inside the country, the authorities are making little kids write essays praising the fallen commander. First-graders who didn’t know how to write were encouraged to cry for Soleimani."
