You are right. Social media is lit up with celebration by Iranians knowing Suleimani is dead. And all we hear from our fake news information channels is that the Iranian People are chanting Death to America.

We have a terrible propaganda problem in the USA. The old news media was nearly bankrupt in 2008-2009 because of competing forms of news outlets like Talk Radio and FR. They ended up being bought out and are now owned by six oligarchs many of whom are foreign based.
But despite the attempt to hide news from the American People, the truth is getting through and I think it’s the same for the Iranian people inside and outside of Iran.
I have many Iranian and Iranian-American friends and none of them are fond of the current regime.
