Iran is right now distributing photos of what they say is their attack that are from 2016/17 Syria, 2018 Gaza, the US attack on Hussein's palace in 2003, and a 2016 explosion of an Iran gas pipeline.
This is just PR.
I read elsewhere that 56 people were trampled to death in a stampede at their chief terrorist's funeral.
I hope, perhaps, that this was a limited attack on well-defended bases where casualties were unlikely specifically because they want a propaganda victory to mollify their population. The same population they just got done machine-gunning for protesting the government, BTW. But if the populace is so ravenous for revenge against the West that they'll trample each other over it, the Iranian government may have no choice. They may actually be afraid their own people will kill them and install someone even more extreme.
