The president/head of the civilian government in Iran was ousted, probably by the IRGC. The IRGC took control of the mullahs a week after the war started. They already had power over them, but the fact us that without the war, the supreme guide election would have been a difficult power struggle with political concessions. It wasn't thanks to Trump, reinforcing the IRGC control of Iran's religious life.

The Iranian regime will be more repressive and more extreme.

The only good point about that is that it makes the regime weaker to domestic insurrections.
